Everything you need to know about painting, decorating, and restoring heritage properties in Hampstead and North London conservation areas.
A conservation area is a designated zone with special architectural or historic interest, where the character and appearance of the area is protected by planning law. Camden alone has over 40 conservation areas, many of which cover the streets and neighbourhoods we serve every day.
If your property sits within a conservation area, certain types of exterior work — including painting, rendering, and altering windows — may require advance consultation with the local council or formal planning consent. Interior work is generally unrestricted unless the building is individually listed.
As specialist heritage property decorators with over 20 years of experience in Hampstead, Belsize Park, and Highgate, we handle conservation area projects regularly. This guide is designed to answer the most common questions homeowners and leaseholders ask before starting work.
A practical overview of which painting and decorating works typically require consent in conservation areas and on listed buildings.
Repainting the exterior in the same colour and finish type (e.g. white masonry in white masonry) does not usually require conservation area consent or listed building consent.
A significant colour change — for example, white to dark grey — may be considered material alteration of the property's appearance. In a conservation area or on a listed building, this typically requires planning consultation or formal consent.
Internal painting and wallpapering in a conservation area property that is not individually listed does not require consent.
Any work that affects the character or fabric of a listed building may require listed building consent — even interior work. Removing historic paint layers, altering original mouldings, or stripping plaster could all need approval.
uPVC replacement of original timber sash windows is almost always refused in conservation areas and is prohibited on listed buildings. Restoration and draught-proofing of existing sashes is the appropriate solution.
Removing or significantly altering external render, stucco, or decorative façade elements on a listed building or in a conservation area requires consent from the local planning authority.
Not sure? We can advise during our free site survey whether your planned work requires any council consultation. We also assist clients with listed building consent applications and conservation officer communications where needed.
We work across the major conservation areas in North London, with deep knowledge of each area's architectural character and regulatory expectations.
One of Camden's largest conservation areas, covering Hampstead Village, Flask Walk, Church Row, Well Walk, East Heath Road, Spaniards Road, and surrounding streets. Predominantly Georgian, Regency, and Victorian properties with many individually listed buildings.
Church Row, Flask Walk, Well Walk, East Heath Road, Spaniards Road, South Hill Park, Keats Grove, Parliament Hill
Fenton House (Grade I), Burgh House (Grade I), numerous Grade II dwellings
Known for its distinctive red-brick mansion blocks, tree-lined streets, and large Victorian and Edwardian villas. External painting should respect the established character of the area.
Belsize Park Gardens, Belsize Avenue, Belsize Crescent, Howitt Road, Lancaster Grove

Conservation-appropriate coatings that protect your building while satisfying planning requirements.
Pre-1919 properties with lime plaster or render
A traditional, fully breathable coating made from calcium hydroxide. It carbonates over time to form a durable layer that allows moisture vapour to pass freely through the wall. Essential for buildings with solid lime-plastered walls where modern acrylic paints would trap moisture and cause damp or blown plaster.

Developed in Bavaria in 1878, Keim works through a process called silicification — the potassium silicate binder reacts chemically with the masonry substrate to form a permanent mineral bond. The result is a vapour-permeable, UV-resistant finish that does not peel, chip, or fade, and can last 20–30 years. Widely accepted by conservation officers.
View service detailsInternal walls in listed properties
A protein-based paint with excellent breathability that produces a characteristically soft, velvety finish. Historically the dominant internal coating for quality interiors prior to modern emulsions. Especially suitable for lime-plastered walls, heritage ceilings, and mouldings.
View service detailsExterior timber, sash windows, doors
A modern coating that allows timber to breathe while still providing robust weather protection. Unlike conventional gloss, microporous paint flexes with timber movement and does not crack or blister, significantly extending redecoration cycles on windows, doors, and fascias.

We advise on conservation area requirements during our free site survey and assist with listed building consent applications and conservation officer communications.
Rather than uPVC replacement, we restore original timber sash windows with new cords, spliced timber, draught-proofing, and microporous paint — at 20–40% of replacement cost.
