In-Frame Kitchens

German Kitchen Door Styles

In-Frame Kitchens.
Furniture quality. Built-in character.

An in-frame kitchen places a solid front frame on every cabinet. Doors and drawers sit inside that frame with small, even gaps all around the opening. From the front you see a border around each door and drawer, which gives the cabinet the quality and presence of a piece of furniture rather than a run of flat panels.

This is the defining distinction between in-frame and every other kitchen construction method. In a frameless German kitchen, doors hang off the cabinet side panels and cover the front edge. In an in-frame kitchen, the front frame is a structural element that is part of the cabinet. The door sits within it. The result is deeper shadows, more visible craftsmanship, and a quality that reads differently from across a room.

Most German and European kitchen systems use frameless construction for the storage and ergonomic advantages it delivers. In-frame appears more often in British, Irish, and bespoke joinery workshops, and in the upper tier of German kitchen brands that serve the UK heritage and period property market. It is not the default. It is a deliberate choice that comes with specific advantages and specific trade-offs.

This guide covers in-frame construction in full, plus a dedicated section on mock in-frame, which delivers the visual character of the style without the access or cost penalties of true construction. Separate guides cover Shaker doors, Skinny Shaker, and handled kitchens.

Section One

What is an in-frame kitchen?

The face frame is the defining structural element of an in-frame kitchen. Vertical stiles and horizontal rails form a rigid frame on the front of each cabinet. Doors and drawer fronts sit within the openings of this frame, inset rather than overlaying it. The gaps between the door and the frame on all four sides are called reveals. Consistent reveals are the mark of quality in-frame construction. Uneven reveals signal either poor fitting or unstable materials that have moved after installation.

In North American kitchen terminology this construction is called inset or face-frame. In the UK market, in-frame is the standard term. The principle is identical in both cases.

The shadow line created by the reveal at each cabinet opening is what gives in-frame its distinctive character. The depth of the shadow changes with light direction across the day, giving the kitchen a visual quality that flat overlay doors do not produce. From across a room, the frame lines give the kitchen the reading of a piece of furniture rather than a row of panels.

Timber doors expand and contract slightly with seasonal humidity changes. Good in-frame systems account for this movement in the reveal dimensions. Inset hinges allow fine adjustment so reveals stay even as the kitchen settles. A kitchen installed in summer with the right reveals should still look right in winter. If it does not, either the reveals were too tight at installation or the materials are not stable enough for the application.

Section Two

How in-frame cabinets
are built.

True in-frame cabinetry relies on a rigid front frame, stable carcasses, quality hinges, and paint systems that hold up across frame joints. The aim is a piece of fitted furniture that performs and looks right for many years without significant maintenance beyond occasional touch-in work on the painted surfaces.

Frames and carcasses. Face frames are typically made from hardwood such as ash, oak, or tulipwood. These timbers are stable, paint well, and hold hinge fixings securely under daily use. Carcasses are built from high-density MFC (melamine-faced chipboard), plywood, or veneered board depending on the maker and price tier. The joints between frame and carcass are a critical detail. A rigid connection produces consistent reveals. A loose or poorly glued joint leads to movement over time.

Hinges and runners. Inset doors use either traditional surface hinges, visible on the face of the frame and door, or concealed inset hinges that sit within mortised pockets in the frame and door. Concealed inset hinges allow three-way adjustment and soft-close action. Drawer runners on in-frame cabinets are full-extension soft-close as standard on quality systems, the same hardware used in frameless German kitchen carcasses.

Painting and finishing. Most quality in-frame makers spray frames and doors with two-part paints or hard lacquers. Two-part paints cure to a hard, durable film that resists marks and cleaning chemicals better than water-based single-component paints. Good primer selection is critical at frame joints where two pieces of timber meet under paint. A micro-crack at a joint reads as a visible line through the colour and is the most common failure point in a painted in-frame kitchen over time.

Face frame, inset hinge, and reveal detail. The quality of the frame joint and hinge setting determines how the reveals look after the kitchen has been in use for several years.

Ask before you order. Confirm whether frames sit on full carcasses or on ladder bases with separate ends. Full carcasses with framed fronts provide more robust structure and a more straightforward installation. Ask whether the face frame is hardwood or engineered timber, and which hinge system is used. The answers tell you a great deal about the quality level of the offer.

Frames and carcasses
Face frames typically use hardwood. Ash, oak, and tulipwood are common choices for stability and paint adhesion. Carcasses use high-density MFC, plywood, or veneered board. The joint between frame and carcass determines reveal stability over time.
  • Hardwood frames hold hinge fixings more securely than softwood alternatives
  • Full carcasses with framed fronts are more robust than ladder-base constructions
  • Frame-to-carcass joint quality determines long-term reveal consistency
Inset hinges
Inset doors use either surface-mounted traditional hinges, visible on the face of the frame, or concealed inset hinges in mortised pockets. Concealed inset hinges allow three-dimensional adjustment and integrate soft-close action without visible hardware on the door face.
  • Three-way adjustment available on concealed inset hinges
  • Traditional surface hinges are part of the design character in period-style kitchens
  • Hinge adjustment keeps reveals even as the kitchen settles over its first year
Painting and finishing
Two-part sprayed paints or hard lacquers are standard on quality in-frame work. Primer selection at frame joints is the critical point. A poor primer allows micro-cracks to open at the joint line under the topcoat. Hand finishing and touch-in work completes corners and detailed edges after installation.
  • Two-part paints cure harder than water-based single-component products
  • Joint priming prevents the most common long-term failure point
  • Colour-matched touch-in paint should be supplied at installation
Plinths and decorative detail
Furniture-style skirting, framed end panels, and cornices reinforce the joinery character and complete the cabinet from every viewing angle. Islands and peninsulas need framed panels on all visible sides. These features introduce additional surfaces that require cleaning and occasional touch-in work over time.
  • Furniture skirting replaces standard kitchen plinths for a freestanding look
  • Framed end panels finish open sides of runs and islands
  • Cornices and light pelmets are proportioned to the frame weight
Section Three

Door styles and materials
for in-frame kitchens.

In-frame describes the cabinet construction. The door style within the frame is a separate design decision. Most in-frame kitchens use Shaker doors because the square, recessed panel of a Shaker front suits the framed opening naturally. Other options include raised and fielded panels, plain slab inset doors, and beaded fronts for more decorative schemes.

Door material influences the look, the maintenance commitment, and how the kitchen ages over time. Real wood is the most authentic choice for in-frame construction and the most refinishable. Painted MDF is the most consistent and the most colour-accurate. Wrapped MDF is the most price-accessible but the least suited to the heat and humidity exposure common in in-frame kitchens near cookers and sinks.

Shaker inset doors
The natural partner for in-frame construction. Square rails and stiles with a flat recessed centre panel. The Shaker profile within the in-frame opening produces the classic English furniture look. The combination of frame shadow and door panel creates deep, layered shadow lines that cannot be replicated in any other construction method.
Raised and fielded panels
A more ornate door profile with a raised centre section. Adds further shadow depth and detailing beyond the standard Shaker. More common in traditional and period-style kitchens where the level of decoration suits elaborate cornice and pilaster work. Requires skilled painting to maintain the crisp profile edges over time.
Slab inset doors
A flat panel door within the in-frame opening. Reduces detailing and suits transitional schemes that sit between traditional and contemporary. The face frame provides structure and character. The door is deliberately minimal. Works particularly well with a strong single colour on both frame and door.
Real wood vs painted MDF
Real wood frames with timber or veneer panels are the most authentic and refinishable option. Painted MDF delivers more consistent colour and sharper edges. Wrapped MDF is price-accessible but vulnerable at edges near heat and steam sources. For in-frame kitchens with long service expectations, real wood or painted MDF are the more appropriate choices.

When reviewing door samples, confirm which elements are solid timber, which are MDF, and whether any wrapped fronts appear in high-heat or high-moisture zones. Material at the frame joint under the paint influences durability more than the door panel specification on its own.

Section Four

Colour and finish.
Where in-frame character is completed.

Painted timber is the defining finish of in-frame kitchens. The colour applied to the frames and doors determines more of the kitchen's final character than almost any other single decision. In-frame holds colour differently to a flat slab or a Shaker door on a frameless carcass, because the shadow lines of the reveals and the depth of the panel rebate change how a colour reads across a room.

Deep colours work particularly well on in-frame kitchens. The shadow depth of the frame makes a rich colour look more resolved and intentional than the same shade applied to a flat slab door. Greens, navies, blacks, and deep greys all carry exceptionally well on an in-frame face. The frame detail gives the colour structure that a flat panel cannot provide on its own.

Most quality in-frame suppliers offer a wide paint programme. Standard colour ranges cover the most common UK choices. Better suppliers extend this to RAL Classic colours for precise colour matching. Some offer colour matching against Farrow and Ball and SIKKENS, which allows the kitchen colour to match joinery, walls, or furniture elsewhere in the property. This matters particularly in period homes where the kitchen is one part of a larger decorative scheme.

Two-tone in-frame kitchens, with a deeper colour on base units and a paler or contrasting colour on wall units, work very well because the frame lines on both levels give the colour transition a visual anchor. The reveals on the base run and the reveals on the wall unit run read as the same construction language even when the colours are different.

Classic neutrals
Off-whites, stone, warm linen, and soft greys. Work in almost all UK property types. Safe choice for resale. Pair with natural stone or oak worktops and traditional brass or nickel hardware. The frame detail provides interest without the colour needing to work hard.
Deep signature colours
Where in-frame excels. Forest green, navy, black, dark teal, charcoal, and deep burgundy all carry exceptional weight on an in-frame face. The shadow lines of the frame give the colour structure and resolve. Pair with pale stone or marble worktops and burnished or antique brass hardware.
Heritage palette
Farrow and Ball and SIKKENS matching brings the heritage paint palette into the kitchen. Shades such as Mole's Breath, Hague Blue, or Purbeck Stone in a sprayed two-part lacquer on an in-frame cabinet give a quality and depth rarely achievable on a standard kitchen door programme.
Two-tone and island contrast
Deeper base units against a paler wall unit run. A contrasting island with furniture skirting. The face frame on both elements holds the composition together visually. The reveal lines on each cabinet are the unifying detail across different colours.

Always view a full door sample in your room. In-frame cabinets with deep colours look very different in showroom lighting versus natural daylight in a north-facing UK kitchen. Request a painted door sample in your chosen colour and live with it in the space for a week before confirming the order.

Section Five

Mock in-frame.
The visual result without the access penalty.

Mock in-frame uses applied beading or planted frame strips on a standard frameless carcass to create the visual impression of in-frame construction. There is no structural face frame. The door overlays the carcass as normal. Thin timber or MDF profiles are applied around each cabinet opening to suggest the frame reveal. The shadow line is created by the applied profile rather than by the structural depth of a true frame.

The practical advantage is significant. The frameless carcass opening is not reduced. Full-width drawer boxes, wide pull-outs, and corner access all remain exactly as they would be on any frameless German kitchen. Mock in-frame gives the visual character of traditional frame construction with the storage performance of a modern system.

The visual difference between true in-frame and mock in-frame is visible at close range to an experienced eye. The reveal in mock in-frame is shallower. The shadow line is less deep. The applied beading sits on the surface of the carcass rather than forming a structural frame around the opening. From across a room, particularly in a busy open-plan kitchen, the difference is far less apparent.

Mock in-frame typically sits in price between standard frameless and full true in-frame. It is a legitimate and increasingly common choice in the mid-market, particularly where buyers want the period character of the in-frame look on a German frameless carcass system with the full range of storage solutions included.

Side-by-side comparison showing true in-frame construction versus mock in-frame applied beading on a frameless carcass

True in-frame vs mock in-frame. The structural depth of the reveal is different at close range. From across the room, the visual character is closely similar.

The question to ask every supplier. Ask explicitly whether their offer is true in-frame with a structural face frame, mock in-frame with applied beading on a frameless box, or frameless with framed-look styling. The word in-frame appears in marketing material for all three. The construction method determines how the kitchen performs, ages, and is serviced. Confirm it in writing on the specification sheet.

True in-frame suits you when
  • The authentic craftsmanship and structural depth of a real face frame matters to you and you are prepared to accept the reduced opening width and the higher project cost.
  • The property is a significant period home where the joinery quality of the kitchen needs to match the quality of the original building fabric.
  • Long-term refinishing rather than replacement is a priority and you want a kitchen that will be repainted rather than replaced in twenty years.
Mock in-frame suits you when
  • You want the visual character of in-frame on a German frameless carcass with the full range of storage solutions, pull-outs, and wide drawer boxes included without compromise.
  • The budget falls between standard frameless and full true in-frame and mock in-frame delivers the aesthetic difference you are looking for within that constraint.
  • The kitchen is in an open-plan space viewed from a distance where the shadow depth of a true frame versus applied beading is not visible in daily use.
Section Six

Planning layouts
with in-frame cabinets.

Layout rules for in-frame kitchens are broadly the same as any fitted kitchen. The face frame places more emphasis on symmetry, alignment, and the relationship between unit widths than a frameless system does, because the frame lines highlight each opening individually rather than allowing doors to flow across a run without breaks.

Symmetry and run balance. Balanced unit widths help frame lines meet neatly around hobs, sinks, and tall units. An uneven run of widths, which barely registers on a frameless kitchen, reads more clearly when frames highlight each opening. At design stage, review the frontal elevation specifically for run balance and unit width relationships.

Tall units and larders. Face frames on tall housings draw attention to floor and ceiling lines. Good scribing at the top and base scribing at the bottom keeps the kitchen looking contained and intentional. Tall in-frame units also reduce the clear opening at the front slightly on each side. Confirm clear access to pull-out larder baskets and appliance doors before the order is placed.

Islands and peninsulas. In-frame islands read as freestanding furniture pieces, which is one of their strongest design qualities in open-plan spaces. Framed panels on the back and sides, furniture-style skirting, and matching cornice detail complete the island from every angle. The result is a piece of furniture in the room rather than a kitchen unit in the middle of it.

Handle alignment. Agree handle height and spacing at design stage. In-frame kitchens are less forgiving of inconsistent handle placement than frameless, because the frame lines provide a visual reference that immediately highlights anything out of alignment. Request the frontal elevation with handle positions marked before signing the order.

Section Seven

Benefits and limits.

Key benefits
  • A furniture-quality look that suits period, cottage, and character properties where the kitchen is expected to reflect the quality of the building it sits in.
  • Visible craftsmanship through frames, reveals, joints, and detail work. The construction method itself communicates quality in a way that overlay doors do not.
  • Strong perceived quality that supports resale appeal, particularly in the mid-to-upper end of the UK property market where buyers expect joinery-quality kitchens in character homes.
  • Painted and timber fronts allow repair, repainting, and colour change over time. The kitchen is refinished rather than replaced. The joinery investment has a longer useful life than a system kitchen at a similar initial spend.
  • Deep colours and heritage paint programmes carry exceptionally well on in-frame faces. The structural shadow depth makes any colour more resolved and intentional.
Points to weigh up
  • Higher material and labour cost than frameless systems at an equivalent specification. The face frame, inset hinge system, and more complex painting process all add to the project cost.
  • Frames reduce the clear access at the front of each cabinet opening. The effect is most pronounced on wide drawers and tall larder units where the frame projects into the opening on each side.
  • More corners, edges, and joints to clean than a frameless kitchen. The reveal rebate at each opening collects dust. Frame corners near the floor collect more than flat slab fronts do.
  • Painted timber near sinks, bins, and busy drawers needs occasional touch-in work. Having colour-matched paint available from the day of installation makes this straightforward rather than a problem.
  • Timber doors expand and contract with seasonal humidity. Well-made in-frame kitchens with adequate reveal dimensions accommodate this movement. Poorly made ones do not, and sticking doors are the result.
Section Eight

In-frame vs frameless
and mock in-frame.

The comparison below covers the three main construction routes for UK kitchens. The carcass materials and hardware within each route can vary widely. The differences described are structural and visual, not about brand or price tier. Dedicated pages on this site cover Shaker doors and handled kitchens in full detail.

Aspect True in-frame Frameless system Mock in-frame
Cabinet structure Structural face frame with inset doors and drawers. Frame is part of the cabinet construction. No front frame. Doors hang off the carcass side panels and overlay the front edge. Maximum opening width. Frameless carcass with applied beading or planted frame strips. Frame effect is visual, not structural.
Storage access Frame reduces clear opening width on each side. Most noticeable on wide drawers and tall larder units. Maximum opening width and height on every unit. Full-width drawer boxes standard. Same access as frameless. The applied profile does not project into the opening.
Visual character Deep shadow lines and structural reveals. The most furniture-quality visual of the three routes. Clean, contemporary lines with no frame breaks. Suits slab, Shaker, and handleless doors equally. Shadow line and reveal impression from applied profiles. Less depth than true in-frame at close range. Similar from a distance.
Colour programme Full paint programme including RAL, Farrow and Ball, and SIKKENS on quality makers. Refinishable over time. Same colour range on German systems. Wide programme including RAL and specialist palettes. Typically follows the frameless carcass colour programme of the manufacturer.
Price position Mid to premium. Higher material, fitting, and paint cost than frameless at equivalent specification. Wide spread from entry-level to premium German systems. Lowest entry price of the three routes. Typically between standard frameless and full in-frame. A mid-position option.
Best suited to Period properties and statement kitchens where joinery character and long-term refinishing matter more than storage optimisation. Projects focused on storage performance, ergonomics, handleless styling, and value per pound spent on cabinetry. Homes that want in-frame character on a frameless system with full storage flexibility and a mid-position budget.

When collecting quotes, ask each designer to label their offer explicitly as true in-frame, mock in-frame, or frameless. The term in-frame appears in marketing material for all three routes. The construction method determines how the kitchen performs, how access works, and what the long-term maintenance involves. Confirm it in writing on the specification sheet before signing.

Section Nine

Typical UK cost bands.

Exact figures depend on room size, specification, region, and building work required. In-frame cabinetry and fitting typically takes a larger share of the total project budget than equivalent frameless systems. When comparing quotes, ask each supplier to split the cost into cabinets, worktops, appliances, fitting, and building work. This makes it possible to identify whether an uplift comes from the in-frame joinery or from another part of the specification.

01
Entry framed ranges
Some suppliers offer framed-look kitchens at accessible price points using simpler door detailing, wrapped MDF fronts, and limited colour palettes. These are typically mock in-frame constructions rather than true in-frame. They suit smaller kitchens or projects where the visual character matters more than deep customisation or the authentic construction method.
02
Mid-market in-frame
Many UK family kitchens with painted hardwood frames, a mix of drawers and larder units, and branded inset hinge hardware sit in the mid-market band. Cabinetry and fitting typically take a larger proportion of the total project budget than equivalent frameless specifications. Worktops, appliances, and flooring are budgeted on top of the cabinet cost.
03
Premium and bespoke
Large kitchens with full-height painted pantries, dresser features, multiple islands, and extensive site-finished joinery work sit at the top end. These projects often involve colour-matched paint programmes, detailed internal fittings, cornice and pilaster detail, and finishing work from specialist joiners on site after the cabinet installation is complete.
Section Ten

Care and maintenance.

Daily cleaning
Use a soft cloth with mild soapy water or a cleaner appropriate for the specific paint system. Wipe frame edges, corners, and handle zones regularly. Avoid harsh chemicals and abrasive pads on painted or stained timber. The reveal rebate at each cabinet opening collects dust and grease. A soft brush along the reveal as part of the weekly clean prevents build-up from becoming a harder task.
Protecting frame surfaces
Frames sit closer to splashes, knocks, and daily contact than slab overlay doors. Treat impacts promptly, particularly on bin drawer fronts and pan drawer edges. A small pot of colour-matched paint supplied at installation makes this a five-minute task rather than a repair job. Keep it in a kitchen drawer and use it at the first sign of any chip before moisture reaches the timber underneath the paint.
Hinge and runner adjustment
Concealed inset hinges offer three-way adjustment. A few small turns keep reveals even if doors settle through seasonal movement or minor joint changes. Check all door reveals once in the first winter after installation. Drawer runners benefit from an annual check to maintain smooth motion and consistent gap alignment. Most adjustments take less than five minutes per door.
Refinishing over time
Many painted in-frame kitchens receive a professional respray or careful hand repaint after ten to fifteen years of heavy use. This refresh retains the full joinery investment and allows a colour update without new cabinets. A kitchen designed for refinishing rather than replacement represents better long-term value than a system kitchen replaced on a ten-year cycle. Ensure the paint system specified at installation is compatible with a future respray.
Section Eleven

Is an in-frame kitchen
right for you?

In-frame suits you when
  • You live in a period or character property and want the kitchen joinery to reflect the quality and craft of the building it sits in.
  • Visible craftsmanship matters to you. Deep frame shadows, visible reveals, and the construction quality of a face-framed cabinet is part of what you are buying.
  • You plan to stay in the property for many years and prefer the idea of refinishing the kitchen in fifteen years rather than replacing it. The joinery investment earns its cost over a longer service life.
  • You want to use deep, considered colours from a heritage paint programme matched to the joinery and decorative scheme elsewhere in the property.
  • Storage access is not the primary concern. The slightly reduced opening width at each cabinet is an acceptable trade-off for the construction quality and visual character you are buying.
Frameless or mock in-frame suits better when
  • You need to maximise every centimetre of internal cabinet width. A compact footprint where full-width drawer boxes and wide pull-outs are a priority favours frameless construction.
  • You prefer a very clean, contemporary, or handleless look with fewer joints, edges, and details to maintain. Frameless systems with slab or handleless doors deliver this more completely.
  • You want the in-frame visual character without the access penalty or the full in-frame project cost. Mock in-frame on a frameless carcass is the practical mid-ground.
  • Value per pound is the primary driver. Frameless German kitchen systems deliver more storage hardware, wider drawers, and more internal fitment options per pound spent on cabinetry than true in-frame at an equivalent price level.

Visit a showroom with both routes on display. Open tall larders, test drawers, and look closely at the reveals on the in-frame display. Then open the same units on a high-quality frameless Shaker display. The practical difference in access and the visual difference in character are both immediately clear in person in a way no guide fully conveys. Also see the Shaker kitchen guide, mock in-frame guide, and handled kitchens guide on this site before booking a design appointment.
