Painting a Period Conversion Flat in London

London's housing stock is heavily defined by conversion flats. Grand Georgian townhouses in Belgravia, Victorian terraces in Pimlico, Edwardian mansion blocks in Kensington, and even some early twentieth-century properties across Chelsea and South Kensington have been subdivided into two, three, or sometimes more separate flats. Each of these conversions presents unique painting challenges that differ significantly from decorating a purpose-built apartment or an intact period house.

This guide addresses the specific considerations that arise when painting a period conversion flat, from navigating shared spaces and divided architectural features to handling the practical and aesthetic complexities that these unusual properties present.

Understanding the Conversion

How Period Houses Are Divided

The way a house was converted determines many of the painting challenges you will face. Common configurations include:

• Horizontal division: The most common arrangement, where each floor or pair of floors becomes a separate flat. The ground and lower ground form one flat, the first floor another, and the upper floors a third. This often means the original entrance hall and staircase become a shared communal area.
• Vertical division: Less common but found in wider properties, where the house is divided front-to-back or side-to-side. This can result in odd room proportions and divided features.
• Mixed arrangements: Some larger houses have been converted in complex ways, with maisonettes spanning two floors alongside single-floor flats, shared corridors at various levels, and multiple staircases.

Each configuration presents different issues. A top-floor flat may have the original servant's staircase as its only access but enjoy the best ceiling heights and cornicing on the principal floors. A ground-floor flat might have the grandest rooms but suffer from damp and reduced light.

Original Features: Divided and Shared

One of the defining challenges of a period conversion flat is that the building's original decorative features were designed for a single house, not multiple dwellings. This creates situations where:

• Cornices run across party walls: When rooms were divided, plaster cornices may have been cut, often roughly, leaving truncated profiles that meet a flat partition wall.
• Ceiling roses are off-centre: Rooms that were subdivided may have the original ceiling rose positioned awkwardly, perhaps partially hidden by a new wall.
• Fireplaces face partition walls: Chimney breasts that were once central features may now sit against or adjacent to a dividing wall, creating cramped or asymmetric arrangements.
• Door casings are split: Original panelled doors and their surrounding architraves may have been removed, replaced with fire doors, or cut to accommodate new room layouts.

When painting these features, the aim is usually to make the best of the existing situation rather than trying to recreate what was there originally. Honest, well-executed paintwork that acknowledges the conversion is always better than poorly attempted restoration.

Communal Areas: Rights, Responsibilities, and Standards

The Lease and the Freeholder

In most period conversions, the communal areas, typically the entrance hall, staircase, and landings, are the responsibility of the freeholder or the management company. Before painting anything in a communal area, check your lease carefully. Key questions include:

• Who is responsible for decorating the communal areas?
• Is there a service charge provision for communal redecoration?
• Are leaseholders required to agree on colours and specifications?
• Can individual leaseholders carry out work, or must it be coordinated?

In buildings managed by estates such as the Grosvenor Estate in Belgravia or the Cadogan Estate in Chelsea, there may be specific requirements regarding colours, finishes, and approved contractors for communal areas.

Coordinating with Neighbours

Even where the lease permits individual action, it is advisable to coordinate communal area decoration with other residents. A freshly painted landing that meets a tired, peeling hallway below creates an awkward contrast. Ideally, communal area decoration should be a building-wide project, carried out by a single contractor to ensure consistency of colour, finish, and quality.

Our commercial painting team regularly handles communal area projects in multi-flat period buildings, coordinating access, maintaining security, and ensuring minimal disruption to all residents.

Communal Area Colour Choices

Communal areas in period conversions benefit from neutral, light schemes that create a sense of space and welcome. Popular choices include:

• Walls: Warm whites and pale stone tones. Farrow & Ball Pointing, Slipper Satin, or Wimborne White work well. Little Greene Slaked Lime and Flint are also popular in Knightsbridge and Belgravia conversion buildings.
• Woodwork: A durable eggshell or satin finish in a complementary off-white. The woodwork in communal areas takes considerable wear from foot traffic and furniture being moved, so durability is more important than a precise colour match.
• Ceilings: A flat matt white. In hallways with good original cornicing and ceiling roses, picking out the cornice in the wall colour, with the ceiling above in white, creates an elegant distinction.

Inside Your Flat: Period Features and Modern Reality

Ceiling Heights and Proportions

The floor you occupy in a converted house often determines your ceiling heights and the quality of decorative plasterwork. First-floor flats in Georgian and Victorian properties typically enjoy the grandest proportions, with ceiling heights of three metres or more and elaborate cornicing. Top-floor flats may have lower ceilings and simpler mouldings, reflecting their original use as bedrooms or servants' quarters.

Understanding the proportions of your rooms is essential for colour selection. The generous ceiling heights of a first-floor flat in Belgravia can accommodate darker, richer colours that would feel oppressive in a lower-ceilinged top-floor conversion. Conversely, very high ceilings in rooms with limited natural light can feel cavernous unless warm tones are used to bring the space down to a more intimate scale.

Dealing with Party Walls and Partitions

Partition walls added during conversion are often built to lower standards than the original walls. Common issues include:

• Different surface textures: Original plaster walls have a distinct texture compared to modern plasterboard partitions. When painting a room that contains both, careful preparation is needed to create a uniform finish. The original plaster may need a mist coat to even out porosity, while the plasterboard joints need careful taping and finishing.
• Cracks at junctions: Where new walls meet old, movement cracks are common. These should be filled with a flexible filler rather than rigid filler, as the two structures will continue to move at different rates.
• Sound insulation: Some partition walls are thin and offer poor sound insulation. While painting cannot solve this, adding a thick lining paper before painting can marginally improve things and creates a superior surface finish.

Original Plasterwork

If your flat retains original cornices, ceiling roses, picture rails, or dado rails, these deserve careful treatment. Heritage painting techniques differ from standard decoration:

• Cornices: Clean out any paint build-up that has obscured the moulding detail. In severe cases, a steam cleaner can soften decades of paint for removal. Once the profile is restored, paint with a brush rather than a roller to work paint into the recesses.
• Ceiling roses: These are often the most elaborate decorative features in a conversion flat. Painting ceiling roses properly requires patience and a steady hand. Consider picking out elements in a contrasting colour for a period-appropriate effect.
• Picture rails and dado rails: These horizontal mouldings provide a natural break point for colour changes. Using a different colour above and below a dado rail, or above and below a picture rail, can add depth and period character to a room.

Fireplaces and Chimney Breasts

Original fireplaces are a significant asset in a conversion flat. The chimney breast itself is an architectural feature that can be used as a focal point:

• Feature walls: Painting the chimney breast in a deeper tone than the surrounding walls draws the eye and emphasises the fireplace. This works particularly well in living rooms and bedrooms.
• Fireplace surrounds: Marble surrounds should be left unpainted but can be cleaned and polished. Wooden surrounds can be painted, stripped, or waxed depending on the style you want. Cast iron inserts and grates benefit from specialist heat-resistant paint.

Practical Considerations

Access and Logistics

Period conversion flats often present logistical challenges for painters:

• Narrow staircases: Moving equipment and materials through tight, winding staircases common in conversion buildings requires planning. Scaffold towers may need to be assembled inside the flat rather than carried up.
• Parking and loading: In areas like Belgravia and Chelsea, parking restrictions can make loading and unloading difficult. Discuss access arrangements with your painter in advance.
• Neighbour consideration: When your flat shares walls, floors, and ceilings with neighbours, be considerate with timing. Sanding, which creates noise and vibration, should be confined to reasonable hours.

Ventilation During Painting

Many conversion flats, particularly those on lower floors, have limited ventilation. When using interior paints, ensure windows can be opened for airflow. If ventilation is poor, discuss low-odour and eco-friendly paint options with your painter. Zero-VOC paints from brands like Earthborn, Graphenstone, and Auro are excellent choices for poorly ventilated spaces.

Damp Issues

Ground-floor and lower-ground-floor flats in period conversions are particularly prone to rising damp and penetrating damp. Never paint over damp walls without addressing the cause first. Signs of damp include tide marks, salt deposits, peeling paint, and a musty smell.

If damp is present, a damp specialist should investigate and treat the cause before any decoration work begins. Painting over damp is a waste of money and will fail within months.
