The Part IV: The Inside – Colour Carcassing, Glass Inserts & the Interior Architecture of the Modern Kitchen

This article, largely informed by recent interactions with potential clients, is Part IV and the last Part of a four-part series designed not only to inform you of the material options available on the market today, but to serve as a lasting reference—a repository of information you can return to whenever you need to make informed, confident decisions on all matters of kitchen design and installation.

In Part I, we explored the boards that form the body of your kitchen. In Part II, we examined the finishes that give those boards their face. In Part III, we surveyed the countertops that bear the daily work of cooking and living. Now we turn to the space that most kitchen guides ignore entirely: the inside.

Open a standard kitchen cupboard. What do you see? If the answer is a plain white interior—bright, functional, and entirely unremarkable—then you are looking at a missed opportunity. The inside of your cabinets is not merely a storage void. It is the surprise your kitchen reveals every time you reach for a plate, a glass, or a spice. In the finest kitchens being designed today, the interior is as considered as the exterior. And that quiet attention to detail is what separates a good kitchen from an unforgettable one.

I learned this lesson gradually, over years of installing kitchens. A client would open a glass-fronted display cabinet to show a guest her dinnerware, and the stark white interior would clash with the warm cream of the doors. Another would stand in front of an open pantry and the raw melamine carcass would feel, for just a moment, like an unfinished thought. The kitchen was beautiful with the doors closed. But a kitchen is not always viewed with its doors closed. It is opened, explored, and lived in. And those moments matter.

1. What Is Colour Carcassing?

Colour carcassing is the practice of finishing the inside of a cabinet—the carcass—in a colour that complements or matches the exterior doors and panels. Instead of a standard white melamine interior, the shelves, side panels, and back panel are manufactured in a coordinated solid colour or textured finish.

The effect is subtle but transformative. A deep charcoal interior behind glass doors creates a dramatic, gallery-like backdrop for white crockery. A warm beige interior inside a solid pantry door greets you with an unexpected softness every time you open it. The kitchen gains a layered, architectural quality—designed not just for how it looks when it is pristine and closed, but for how it feels when it is in use.

PG Bison has embraced this trend with a dedicated Colour Carcass Range. It includes four solid colours—Cappuccino, Congo, Folkstone Grey, and Storm Grey—and two textile-inspired prints, Luca Polenta and Luca Urban. These are available as 3mm SupaWood backers in a 9x6 board size, designed for better yield and less waste. The solid colours come in both PEEN finish (to match high-gloss SupaGloss frontals) and STRATA finish (to pair with ultra-matte SupaMatt doors). Matching backs mean that every visible surface inside the cabinet carries the same finish as the front.

2. Why Colour Carcassing Matters

The argument for colour carcassing is not merely aesthetic. It is practical, emotional, and increasingly, a marker of quality.

• Aesthetic Continuity. When a cabinet is opened, the eye should not be jarred by a sudden change in colour or texture. A coordinated interior extends the design language of the kitchen into the hidden spaces, creating a sense of completeness.

• Perceived Value. A kitchen with colour-carcassed interiors feels more expensive. It signals to anyone who opens a drawer or a pantry door that no detail was overlooked. This is the kind of quiet luxury that impresses without shouting.

• Light Management. Darker carcass colours absorb light, which can be advantageous behind glass doors where you want the illuminated contents—white porcelain, crystal glassware—to stand out. Lighter carcass colours reflect light, making a pantry feel brighter and more spacious.

• Personalisation. The six colours in PG Bison's range, combined with the choice of PEEN or STRATA texture, allow for a degree of customisation that makes the kitchen feel uniquely yours.

3. Where Colour Carcassing Has the Most Impact

Not every cabinet requires a colour carcass. The investment should be targeted where it will be seen and appreciated.

• Glass-Fronted Display Units: This is the most obvious application. The back panel of a glass display cabinet is visible at all times. A matching or contrasting carcass colour sets the stage for whatever is displayed inside.

• Open Shelving: Open shelves, whether in the main kitchen or a scullery, reveal their backing wall. A coordinated finish ties them to the rest of the kitchen.

• Walk-In Pantries: The pantry is a room within a room. When every shelf and panel inside is colour-matched, the pantry feels like a deliberate, designed space rather than a storage afterthought.

• Drawer Interiors: While less visible than a display cabinet, the inside of a cutlery drawer or pot drawer is seen multiple times a day. A matching base and sides create a subtle but satisfying experience every time the drawer is opened.

• Wine Racks & Specialised Units: These feature units are often partially open by design. A coordinated interior finish ensures they look intentional.

4. Glass Inserts & Shelving: The Visible Interior

Colour carcassing finds its most powerful expression in combination with glass. In Part I, we touched briefly on glass display units. Here, we give them their full due.

Glass-fronted cabinets serve a dual purpose: they protect their contents from dust while putting them on display. The glass itself can be clear or frosted. Clear glass is ideal for showcasing beautiful dinnerware, glassware, or curated collections. Frosted glass, typically 3mm in thickness, softens the view and conceals clutter while still allowing light to pass through—a practical choice for busier storage areas.

Inside these cabinets, glass shelves—usually 4mm thick—replace standard melamine shelves. They are stronger than they look, and their transparency allows light to flow vertically through the cabinet. When LED strip lighting is integrated into the cabinet frame, the glass shelves seem almost to float, each one carrying its load of carefully arranged objects in a column of warm light.

The interaction between the glass, the light, and the colour carcass behind it is what elevates a display cabinet from functional storage to interior architecture.

5. Practical Considerations

Colour carcassing is not automatically included in standard quotations. It is typically an upgrade, and it carries a cost premium over standard white melamine interiors. The additional investment varies depending on the number of units specified, the chosen colour, and the board thickness required.

However, because PG Bison's colour carcass backers are manufactured in a larger 9x6 board size, there is less waste during cutting, which helps contain the cost. For most kitchens, specifying colour carcasses for glass-fronted units, open shelving, and the pantry represents a modest percentage of the total project cost while delivering a disproportionate impact on the finished feel of the kitchen.

6. Where the Future Is Heading – Interiors

The trend toward considered interiors is accelerating. Several developments are worth watching:

• Textured Interiors: Beyond solid colours, textured and patterned interior surfaces—such as the Luca textile prints from PG Bison—are growing in popularity. They add a tactile dimension to the inside of a cabinet, making the simple act of reaching for a plate a sensory experience.

• Integrated Interior Lighting: LED strips are increasingly being embedded directly into shelf edges and cabinet frames at the manufacturing stage, creating a seamless, built-in lighting solution that requires no surface-mounted fixtures.

• Smart Interiors: Cabinets with internal sensors that activate lighting when the door opens, or that track inventory and send shopping reminders, are beginning to appear in concept kitchens. While still a novelty, they point toward a future where the interior of the cabinet is as intelligent as it is beautiful.

• Antimicrobial Interior Surfaces: The same silver-ion and copper-based antimicrobial technologies being developed for external boards are likely to find their way into interior panels, particularly for pantries and food storage areas where hygiene is paramount.

Closing the Series: The Kitchen as a Complete Work

We began this series with a simple observation: that I once chose natural oak melamine for my very first kitchen because it looked like wood to me, and I had no idea of the universe of choices that existed. Four parts later, we have journeyed through the boards that form the body of the kitchen, the finishes that give it a face, the countertops that bear its daily work, and now the interiors that complete its character.

A kitchen is never just one decision. It is a thousand small decisions, each one shaping how the space looks, how it functions, and how it makes you feel. The board you choose for your carcasses. The finish on your doors. The stone beneath your hands. The colour that greets you when you open a cupboard to reach for a coffee cup in the quiet of the early morning. Every one of these decisions matters.

And every one of them is a decision you do not have to make alone. If you have read this far, you are now equipped with a deeper understanding of kitchen materials than most homeowners ever acquire. You know what questions to ask. You know what trade-offs exist. You know that veneer is not always cheaper than spray-painting, that granite can take a hot pot directly from the stove, and that the inside of your pantry deserves as much thought as the front of your island.

My job, when I sit down with a client, is not simply to install a kitchen. It is to help you navigate this universe of choices with confidence, to bring clarity where there is confusion, and to ensure that the finished space feels like it could never have been any other way.

I have come a long way from natural oak. And if I have done my job with this series, you have too.
