Painting a New Build Apartment in London: The First-Time Owner's Complete Guide

London's new build apartment market serves buyers across the full spectrum of specification and price, from the premium riverside developments of Nine Elms and Battersea Power Station to the more modestly specified schemes of inner zone regeneration areas. Whatever the specification of the apartment itself, the first decoration after handover is the moment when the owner moves the property from what the developer made to what they want it to be — and getting this right requires understanding the specific challenges that new build properties present.

We decorate new build apartments across all of London's major development zones — the South Bank, Battersea, Victoria, Nine Elms, King's Cross, Paddington, and the ongoing developments in east and south-east London that are expanding the premium residential market. This guide distils what we have learned from hundreds of first-decoration projects into practical advice for buyers planning their initial scheme.

The New Plaster Problem

Every new build apartment has newly plastered walls, and new plaster requires specific treatment before it can accept a conventional paint system. This is the single most important technical point for any buyer planning to decorate their new build immediately after handover.

The drying timeline. Modern gypsum plaster — the type used in virtually all new build apartments — takes approximately one month per millimetre of thickness to dry to a level where it can be painted without risk of adhesion failure. A standard skim coat is approximately 2mm thick, requiring at minimum six weeks of drying time, and ideally three months for reliable stability. Developers typically hand over properties before this drying period is complete, often because they are financially motivated to hand over as soon as the regulatory sign-offs are obtained.

What happens if you paint too early. Painting over insufficiently dried gypsum plaster seals moisture into the plaster, which then drives through the paint film as it slowly dries over subsequent weeks and months. The result is a paint surface that blisters, bubbles, and peels — often dramatically, with entire sections of emulsion lifting from the wall in sheets — requiring complete stripping and repainting after the plaster has finally dried.

The mist coat. The appropriate first coat on new plaster — regardless of how well it appears to have dried — is a mist coat: standard emulsion thinned 10-20% with clean water and applied as a single thin coat across the entire surface. The mist coat soaks into the surface, stabilising any remaining loose particles, providing a consistent absorbent base for subsequent coats, and — critically — confirming by its appearance when dry whether the plaster has dried adequately (even colour) or retains moisture (darker patches or patches with different reflectance). If the mist coat reveals moisture-related issues, we advise delaying full decoration until the plaster has dried further.

Working with Developers: Pre-Handover Painting

Many London new build developers offer a "purchaser specification" programme that allows buyers to upgrade the interior decoration specification before handover, typically at a cost that is folded into the purchase price and requires approval before a cut-off date during construction. We work with buyers at this stage to help them specify upgrades that represent genuine value — focusing on surfaces where developer standard finishes are most limiting and where custom specification makes the biggest visual difference.

Joinery specification is where developer standard finishes most frequently disappoint: the flat eggshell or semi-gloss applied to MDF skirting boards and architraves by developer teams is typically adequate in coverage but applied too quickly to develop the smooth, hard surface that premium specification demands. Requesting the developer to leave joinery unfinished — or specifying a full removal and refinishing of all joinery surfaces — and commissioning our spray-finishing service before occupation produces a result that no developer-speed brush finish can match.

Kitchen and bathroom tiling decisions affect what decoration is possible on adjacent surfaces. Where buyers have specified or accepted the developer's tile scheme, the adjacent wall colours and finishes must be chosen in relation to it, and we advise strongly against specifying wall colours before the tiles are in place and viewable in the actual room under its actual light conditions.

Typical Timeline for a New Build Decoration Programme

Our recommended timeline for a London new build apartment decoration programme:

At or before handover: Agree the colour scheme and specification with our team, based on the apartment's orientation, light quality, and design intention. Do not purchase or apply any paint yet.

4-8 weeks after handover: If your developer has used good ventilation practices and the plaster has dried adequately (moisture meter readings below 20%), apply mist coat on all walls and ceilings. Assess results. Apply two finishing coats of emulsion if mist coat results are positive.

8-12 weeks after handover: If mist coat results were ambiguous or plaster drying was slow, apply finishing coats of emulsion now. Begin joinery finishing programme.

12-16 weeks after handover: All decoration complete, apartment fully occupied and aired. Final review of any areas requiring touch-up before furniture and art are installed permanently.

Colour in London New Builds: Navigating Limited Natural Light

Many London new build apartments — particularly in the large mixed-use blocks that dominate current development — have less natural light than the Victorian and Georgian period properties they neighbour. South-facing apartments in tall buildings may receive excellent direct light; north-facing units on lower floors may depend almost entirely on artificial lighting. The colour approach for these two scenarios is completely different.

Well-lit south and west-facing apartments support a wide range of colour choices, including cooler tones that can look flat in north-facing rooms and richer, more saturated colours that need light to prevent them from appearing gloomy. In these apartments, the main constraints on colour are personal preference and the palette of any existing furniture and fittings.

North-facing and lower-floor apartments benefit from warm tones that add the apparent warmth that limited natural light fails to provide: the warm whites and off-whites of Farrow & Ball's Pointing, Little Greene's Bone, and Dulux Heritage's Soft Stone; or the warm grey-beige tones that photograph and live beautifully in apartments that receive good quality diffuse light without direct sun. Avoid cool whites, cool greys, and blue-grey tones in north-facing apartments; these colours will read flat and slightly cold in the available light.

Apartment-specific colour assessment. We provide all new build clients with on-site colour assessment — applying large test patches in the actual rooms at the actual time of day when the apartment will primarily be used — before specifying any colours. The combination of the apartment's orientation, floor level, window size, and ceiling height (often lower in new builds than period properties) makes colour assessment in the actual space particularly important.

Premium Specifications for New Build Apartments

The most common upgrade requests we receive for new build apartments are:

Spray-finished joinery. Airless spray application of all skirting boards, architraves, and door surrounds produces a surface quality impossible to achieve with brush or roller — the factory-smooth result that distinguishes premium specification interiors. We prepare, mask, spray, and de-mask in a single efficient sequence that minimises disruption and maximises finish quality.

Feature walls and alcove finishes. Venetian plaster as a feature wall behind a headboard or in a dining room; a metallic or textured finish in a bathroom or study; a richly pigmented colour in a bedroom — these premium finishes transform the character of a new build interior at relatively modest cost and create the points of distinction that make an apartment feel curated rather than standard.

Kitchen cabinet respraying. Developer kitchen cabinets are frequently in acceptable but uninspiring colours. Our kitchen respraying service — using Renner two-pack polyurethane lacquer in any colour the client specifies — changes the kitchen completely at far less cost than replacement, matching any Farrow & Ball, Little Greene, or RAL reference.

Bathroom refresh. Developer bathroom tiles and fixtures are typically chosen for their ability to satisfy the broadest market rather than for design distinction. Where changing tiles is not feasible (the costs and disruption are significant), changing the wall paint colour above the tile line and refinishing the vanity unit can dramatically transform the space. We use specialist moisture-resistant formulations for painted areas in bathrooms, ensuring long-term performance in this demanding environment.

Costs and Value

The cost of a complete first decoration for a London new build apartment — mist coat, two finishing coats on walls and ceilings, full joinery preparation and finishing — typically ranges from £2,500 for a one-bedroom apartment to £8,000 for a three-bedroom premium apartment with complex specifications. Feature wall treatments, spray finishing, and bespoke decorative finishes add to this range.

The value of investing properly in the first decoration is measurable: in the London rental market, a well-finished apartment commands premium rent and attracts longer-tenancy applicants; in the owner-occupier market, the quality of decoration is the primary factor in how much buyers perceive the apartment to be worth. A good first decoration is not a cost to be minimised — it is an investment in the property's presentation and its owner's enjoyment of it.
