Painting Open Plan Spaces in London: Colour Zoning and Unified Schemes

Open Plan Living in London Homes

The open plan arrangement — kitchen, dining and living areas combined into a single flowing space — has become the dominant layout in London flat renovations and house extensions over the past two decades. Removing a wall between kitchen and reception room is the most common single improvement made by London homeowners, creating spaces that feel larger, more social and better suited to contemporary family life.

But the open plan format creates a distinct decorating challenge. A single large space with different functional zones, potentially multiple light sources and often varying ceiling heights raises questions that a conventional room layout does not: Do you use one colour throughout? How do you define the kitchen area without physical walls? How do you handle the transition between zones? How does the colour read from the far end of the room?

The Case for a Unified Palette

The strongest single piece of advice for decorating an open plan space is to resist the temptation to treat each zone as a separate room and use too many different colours. In a large connected space, multiple distinct colour areas create a fragmented, busy feeling that reduces rather than enhances the sense of openness.

A unified palette — using one or two colours consistently throughout the space — works with the open plan layout rather than against it. The eye can travel across the full length of the room without visual interruption, reinforcing the sense of scale and coherence.

This does not mean the space has to be monotone. A single wall colour used throughout with white or near-white ceiling and consistent woodwork colour across all zones creates a unified backdrop that reads as one room. Variation in materials — timber floor, kitchen units, upholstery, blinds — provides the interest and differentiation between zones without requiring multiple paint colours.

In Kensington, Notting Hill and Chelsea, where ground floor kitchen-living extensions are common in period terraces, this unified approach is the standard professional recommendation. The most successfully decorated examples treat the entire back-of-house as a single room despite the change in function.

Using Colour to Define Zones

Where differentiation between zones is wanted, there are several approaches that achieve it without the fragmentation of entirely different wall colours.

Accent wall within a zone. A single wall behind a kitchen island or within the seating area can carry a stronger or contrasting colour without the overall palette feeling disjointed. This works best when the accent colour is related to the main colour — a deeper shade of the same hue, or a clearly considered complement.

Ceiling height changes. In many London ground floor extensions, the original house section has a higher ceiling than the extension. This natural break in the ceiling plane can mark the transition between zones. Using a slightly different treatment above the extension — a bold ceiling colour, exposed timber, or simply a different tone — respects the architectural transition without requiring different wall colours throughout.

Joinery and cabinetry as zoning tools. Kitchen units, shelving and fitted furniture are more effective zone-definers than wall colour. A dark painted island unit or a run of cabinetry in a contrasting colour defines the kitchen area clearly without the wall colour changing. This is architecturally more sophisticated than using paint alone.

Managing Light Across a Long Space

Open plan spaces in London's terraced houses often have light entering from both ends — a front bay window and a rear garden extension — with a darker central zone between them. This light pattern has significant implications for colour choice.

A colour that looks warm and inviting at the well-lit rear of the space may look flat and dingy in the darker central section. Testing colour samples in multiple positions within the space, at different times of day, is more important in an open plan room than in any other room type.

As a general principle, warm mid-tones handle variable light conditions better than cool colours. Warm greys, soft putties, earthy clay tones and warm off-whites read well across a range of light conditions. Cool blues and greens can look attractive in the bright rear section and lifeless in the darker central zone.

If the space is predominantly north-facing — common in garden extensions on south-facing terraced houses, which by definition have their extension on the north side — lean towards warmer colours and avoid anything with strongly blue or grey undertones.

Kitchen Finishes Within the Open Plan

The kitchen section of an open plan space has particular practical requirements. Wall surfaces behind cooking areas and above worktops need to be cleanable — standard emulsion is not appropriate here. Options include:

• Specialist kitchen paint — formulated to be more resistant to grease and moisture, available from Dulux, Farrow & Ball and others
• Tiles or splashback panels — which can either match or deliberately contrast with the wall colour
• Eggshell or satinwood paint on the kitchen section walls, with standard matt emulsion continuing throughout the living and dining areas

The transition between paint finishes, if used, should fall at a natural break — a door reveal, a beam, the edge of a run of cabinetry — rather than at an arbitrary point on a continuous wall surface.

Woodwork Colour in Open Plan Spaces

In a conventional room, off-white or white woodwork is standard. In an open plan space, this convention holds but with one important consideration: consistency. With skirting boards, architraves, window frames and potentially structural steel visible across a large area, any variation in the woodwork colour is very apparent.

Use a single woodwork colour throughout the entire open plan space. In London conversions where original period joinery meets new-build extension elements, matching the paint colour precisely ensures visual continuity. A near-white — Farrow & Ball All White or Little Greene Linen — often bridges old and new elements more gracefully than a stark brilliant white.

The Long View

The most important factor in decorating an open plan space is considering how it reads from its furthest viewpoints. Stand at the entrance to the space and look to the far end. Stand in the kitchen and look back into the living area. The colour, finish and overall palette should look intentional and coherent from every angle.

This is where open plan spaces reward professional advice. An experienced decorator who regularly works in London homes will often see immediately what a homeowner making colour choices in isolation misses: that a colour selected in the kitchen context will look entirely different from the opposite end of the living room. Getting that judgement right makes the difference between a space that feels considered and one that simply feels large.
