Decorating a London Penthouse: The Complete Decorator's Guide

Why Penthouse Projects Demand a Different Approach

A London penthouse is not simply a large flat painted in the same way as any other. The combination of floor-to-ceiling glazing, double-height or unusually tall ceilings, exposed structural elements, and the expectation of a finish that reads as genuinely luxurious places this category of work in a different bracket entirely. Decorators who approach it like a standard residential repaint produce results that disappoint at that level of the market.

This guide covers the specific technical and logistical considerations that define a high-quality penthouse decoration project.

Working Around Floor-to-Ceiling Glazing

Large glazed panels are the defining feature of most London penthouses, and they create two serious practical problems.

First, natural light is intense and raking. Any imperfection in a plastered wall or a painted surface — a trowel mark, a missed run, a roller stipple left in the finish — will be picked out mercilessly by bright light entering at a low angle, particularly in the morning and evening. This means preparation standards must be significantly higher than on a typical interior project. Walls often need a full skim skim to fill trowel marks before any paint is applied, and the finishing coat must be applied in controlled conditions with the decorator checking across the surface with a torch at multiple angles before signing off.

Second, large expanses of glass mean the colour you select on a small chip will shift dramatically once it is on the wall. A warm greige that reads beautifully in a chip can turn distinctly cold against a grey London sky, or blow out entirely in direct summer sun. Sample boards — painted sections at least 500mm square — should be assessed at different times of day before any final commitment.

High Ceilings: Access, Product Choice, and Visual Proportion

Double-height ceilings introduce access challenges, but they also affect how paint reads. At four or five metres, a standard emulsion finish can look flat and characterless. Many of the best penthouse projects use a specialist finish on ceilings — either a high-build limewash for a soft, luminous quality, or a fine mineral plaster paint such as Keim Ecosil or Farrow & Ball's Estate Emulsion in a carefully chosen tone — to add depth and warmth.

For access, scissor lifts are often the right tool on open-plan floors where there is space to manoeuvre. Towers work on more constrained layouts. On projects where the interior designer has specified polished concrete or high-end stone flooring already in place, all equipment must be fully padded and floor protection laid before any work begins.

Bespoke Colour and Finish Work

Penthouses frequently involve decorative finishes beyond flat paint. Common specifications include:

Venetian plaster panels on feature walls or bedroom headboard walls, applied in Tierrafino or Stucco Antico systems. These require a dedicated application technique and typically two or three layers, each burnished when partially dry.

Colour-washing and layered finishes to create depth on large, flat wall expanses that would otherwise feel institutional.

Lacquered or hand-painted joinery in bespoke colours, often matched to the interior designer's specification using Little Greene, Papers & Paints, or a custom Farrow & Ball match.

Coordinating with Interior Designers

Most penthouse projects in London involve an interior designer, and the decorator's role shifts accordingly. The decorator is not specifying finishes — they are executing someone else's vision, and the relationship requires clear communication about what is technically achievable, what scheduling looks like around other trades, and where the decorator needs sign-off before proceeding.

Practical points: always get the specification in writing before ordering materials. If the designer has specified a finish you have not worked with before, be transparent about that and allow time for a test panel before full application begins. Never substitute a product without written approval — on luxury projects, the designer will notice.

Product Specification at This Level

At penthouse level, the product specification typically steps up. Fired Earth, Little Greene, Farrow & Ball, and Edward Bulmer Natural Paint all feature regularly. For joinery, Mylands Gloss or Little Greene Intelligent Gloss in eggshell delivers a factory-quality finish with far less brush marking than standard trade paints. For feature plaster walls, a limewash from Limebase or Kalk & Krita provides a quality of light that no emulsion can replicate.

Do not use trade emulsions — even good ones — on a project where the client is paying penthouse prices. The difference in finish is visible.

Before You Quote

Visit the property before submitting a price. Photograph existing surfaces, note any staining or previous decorative treatments, and establish access logistics. Penthouse projects often have building management rules around delivery times, goods lift usage, and working hours. Factor all of this into the programme before you agree a start date.
