Painting Below-Stairs Spaces in London Homes: Making the Most of Awkward Areas

Why Below-Stairs Spaces Deserve Proper Attention

The space beneath a staircase is one of the most commonly neglected decorating jobs in London's period terraces and townhouses. It is typically finished in whatever paint was left over from a previous project, never quite matches the hallway, and accumulates scuffs and marks faster than any other surface in the house. In larger properties it may conceal a downstairs WC, a utility area, or a small study or coat cupboard — spaces that see daily use but are rarely given the same care as the main rooms.

Done well, a below-stairs space can be a design asset. In the estate agent lexicon of London period homes, a fitted out and attractively decorated below-stairs cupboard is a selling point. In daily life, a well-considered finish makes even a cramped utility space feel purposeful rather than forgotten.

The Practical Challenges

Below-stairs spaces share a set of practical decorating challenges regardless of the property type:

Access and geometry — the angled soffit of the staircase creates an awkward diagonal surface that slopes from a full height at one end to often less than a metre at the other. Painting into corners where the soffit meets the side walls requires small brushes and a degree of physical flexibility. Rollers are often impractical in the tightest sections; a 50–75mm brush may be the only viable tool for much of the work.

Darkness — most below-stairs spaces receive no natural light, or at best a very small amount filtered through a half-glazed door. Working in a dark space is uncomfortable and makes it hard to see preparation deficiencies, holidays in paint coverage, and wet edges. Bring a work light before starting; a clip-on LED bar is sufficient and significantly reduces the chance of missed areas.

Ventilation — in a sealed cupboard with no window, solvent-based paints can build up fumes quickly. Use water-based products throughout, leave the door open during painting and drying, and take regular breaks. For small spaces, personal protective equipment (a well-fitted respirator) is worthwhile even with water-based coatings.

Humidity — below-stairs spaces in London terraces, particularly in ground-floor areas, are often the dampest part of the hallway. A space adjacent to an external wall or above a cellar may experience higher humidity than the rest of the property. Check for damp before painting; if the walls are cool and slightly clammy to the touch, investigate before applying paint.

Surface Preparation

The below-stairs soffit and side walls are typically the same construction as the rest of the hallway — plasterboard or plaster on lath — and should be prepared in the same way. Particular attention should be paid to:

• Scuffs, dents, and damage at low levels (where bags, shoes, and equipment are stored)
• Any water staining or tidemark on the walls at low level, which should be investigated for source before being painted over
• The junction between the soffit and the stair string (the structural timber that runs along the side of the staircase) — this joint often has a gap that needs caulking before painting

Fill all damage with a fine surface filler, sand smooth, and spot-prime bare areas. Caulk all junctions and allow to dry before applying paint.

Product Selection

For below-stairs spaces, a durable, washable finish is more important than in any other part of the hallway. These spaces receive concentrated use — people crouching, reaching, storing shoes and coats — and the surfaces get marked frequently.

A water-based eggshell or a durable mid-sheen emulsion is the right choice for walls and soffit. Flat matt emulsion shows every mark and is very difficult to clean; avoid it in these spaces. A satin or semi-gloss water-based paint is an even more robust option where durability is the priority.

For any exposed timber elements — the stair string, any shelving, the door frame and door — a water-based eggshell in a colour that works with the hallway woodwork is standard. Keep the timber and wall colours coordinated with the hallway rather than making the below-stairs space a separate scheme; visual continuity through the door makes the hallway feel larger.

Colour Strategy

The temptation in a dark, enclosed space is to go pale in order to maximise apparent brightness. This is logical but not always the most effective approach. A very pale colour in a space with no natural light can read as cold and institutional; the artificial lighting casts it in a yellow or blue tone depending on the bulb, and the result rarely looks as bright as anticipated.

An alternative approach that works well in London period hallways is to treat the below-stairs space as a continuation of the hallway rather than a problem to be solved separately:

• Match the walls to the hallway wall colour, or to a deeper tone within the same palette
• Use the same woodwork colour throughout
• Add focused lighting — a simple LED strip inside the cupboard, or a small pendant or wall-light if the height allows — rather than relying on reflected colour to create the impression of brightness

A dark, intentional finish — deep navy, bottle green, charcoal — can also work well if the space is clearly a defined cupboard rather than part of the circulation. Painting the inside of a fitted cupboard in a strong accent colour is a practical way to add character without committing to it in the hallway proper.

When to Do It

Below-stairs painting is a natural addition to a hallway and staircase project but can also be done as a standalone job. Because access is contained and the surface area is relatively small, it is a quick, high-impact piece of work. In a London terrace that is being prepared for sale or tenancy, the below-stairs cupboard is one of the spaces that buyers and tenants look at closely — a fresh, well-finished space signals care and attention throughout the property.
