Interior Painting Tips for Small London Flats
Most London flats are compact. That's not a complaint — it's a fact of the market — and with the right approach to decoration, a small flat can feel significantly more spacious, coherent, and polished than its square footage would suggest. Paint is the single most powerful tool you have for transforming a small space, and it costs a fraction of what structural changes or new furniture would run to. Here's what we've learnt from decorating hundreds of London flats.
The Single Biggest Mistake: Defaulting to White Everywhere
The instinct to paint everything brilliant white in a small flat is understandable — white reflects light, feels clean, and seems safe. But in practice, a flat painted in stark brilliant white often reads as clinical and actually emphasises the boundaries of a small room by making every wall, corner, and angle hyper-visible.
A better approach is to choose a considered warm or cool off-white — something like Farrow & Ball's All White, Little Greene's Loft White, or Dulux Heritage's Chalk White — which reflects just as much light but with a warmth that makes the space feel lived-in rather than institutional. The difference on the day is subtle; the difference over a week of living in the space is significant.
Colour Continuity: The Most Effective Space Trick
In a small flat, using the same colour throughout — or a tightly related family of colours — creates a visual continuity that makes the space read as larger and more unified. When you walk from a hallway in one colour into a living room in a different colour and a kitchen in another, the eye registers each change as a boundary and the space feels chopped up.
Running a single colour through the hallway and all the main rooms, or using the same colour with very slight variations in tone across different spaces, removes those visual interruptions. Even if the total square footage hasn't changed, the flat feels more generous.
This works particularly well with the woodwork. If you paint skirting boards, door frames, and doors in a tone closely related to the walls — a classic colour drench — rather than contrasting white, you eliminate another set of visual boundaries and the eye reads the space as a continuous whole rather than a series of separate boxes.
Ceilings: Go Lighter, Go Reflective
In a standard small flat with eight-foot or nine-foot ceilings, the ceiling is a significant visible surface. Painting it in the same colour as the walls makes the room feel like a box. Painting it significantly lighter — either white or the palest possible tint of the wall colour — draws the eye upward and increases the sense of height.
For rooms where you want to maximise this effect, consider a ceiling paint with a very slight sheen. A flat white ceiling absorbs light; a ceiling with even a hint of eggshell finish bounces it back into the room. We're not talking a high gloss here — just enough sheen to add some luminosity. In a north-facing flat that doesn't get much direct sun, this can make a real difference.
Alcoves and Storage: Colour as Architecture
Small London flats often have alcoves alongside chimney breasts — in Victorian and Edwardian conversions particularly. These alcoves are frequently used for bookshelves or fitted storage, and how you paint them is an opportunity to add visual depth and interest.
Painting the back wall of an alcove in a deeper tone than the main walls creates a pocket of depth that reads as a visual feature rather than a space constraint. If you have open shelving in the alcove, a contrasting back wall turns the books and objects into a display rather than just storage. It's a small detail that makes a flat feel more considered.
If you have fitted wardrobes or built-in storage, painting the door faces in the same colour as the surrounding wall — rather than a contrasting white or wood finish — makes them recede visually and reduces the sense that the room is dominated by storage.
Sheen Levels in Small Flats
Sheen level choices in a small flat matter more than in a larger house. In a small living room, using a full flat or dead-flat emulsion on walls gives the most sophisticated result — dead-flat paints absorb light and make surfaces feel soft and three-dimensional, which counteracts the boxy feel of a small room. Farrow & Ball's Estate Emulsion or Little Greene's Intelligent Matt are good examples.
In kitchens and bathrooms — which in a London flat are often very compact indeed — use a higher sheen: an eggshell or kitchen-specific emulsion that wipes down easily. The practical need for cleanability in these rooms outweighs the aesthetic argument for dead flat.
Hallways in small flats take a lot of traffic and abrasion; use an eggshell or soft sheen here too, but keep the colour consistent with the rooms it leads to.
Painting to Disguise What You Can't Change
Every small flat has something awkward — a boiler cupboard in an odd position, a load-bearing column, a low beam, an asymmetrical wall junction. Paint can minimise many of these. Painting a structural column the same colour as the surrounding walls makes it recede. Painting a low beam to match the ceiling rather than the walls removes it from the foreground of the room. Painting the inside of a cupboard the same colour as the room interior softens the visual interruption when the door is open.
None of these tricks require anything other than a tin of paint and a careful brush — but collectively they make a significant difference to how a small flat reads and feels.
