Careful construction for Chelsea properties
Prohaus undertakes renovations, extensions, loft work, kitchens, bathrooms and bespoke joinery in Chelsea. Period fabric, shared buildings, valuable finishes, limited access and strict planning controls make preparation especially important, so we define the scope and interfaces before construction starts.
Homes and projects in Chelsea
Chelsea contains some of London’s most distinctive residential buildings. The right approach is rarely the loudest one: it is the one that respects the existing property, solves the technical constraints and delivers calm, durable rooms.
Prohaus serves Chelsea, Brompton, World’s End, Royal Hospital, Lots Road and the King’s Road area.
Selected Prohaus work across South West London
We currently have no verified Chelsea case study to publish, so we do not label another area’s project as Chelsea work. These genuine Prohaus projects show relevant renovation, extension and joinery standards nearby.
Genuine work, accurately labelled
For Chelsea enquiries, we assess access, working-hour or building-management rules, protection of common areas, neighbour interfaces and the level of finish before the programme is agreed. A detailed pre-start scope is especially valuable where the property is occupied or forms part of a managed building.
What we build in Chelsea
One coordinated plan connects the structure, services, carpentry, glazing, plastering, tiling and finishes. This makes responsibilities clearer and helps the work proceed in the right order.
House extensions
Rear, side-return and wraparound extensions designed around the existing structure, daylight, storage and how the new room will connect to the garden.
Loft conversions
Dormer, rooflight and hip-to-gable options considered against head height, stair position, roof form, neighbouring properties and planning constraints.
Home renovations
Structural alterations, services, insulation, plastering, flooring, decorating and fitted elements coordinated as one practical programme.
New builds
Residential construction delivered from approved information, site preparation and structural work through to finishes and handover.
Kitchens and bathrooms
Standalone or wider-project kitchen and bathroom work, with the building, plumbing, electrical, tiling and finishing stages properly sequenced.
Doors, windows and glass
Aluminium doors and windows, architectural glazing and openings formed to bring in light and improve the connection to outside space.
Bespoke joinery
Made-to-measure wardrobes, alcove units, media walls, benches, shelving and storage for difficult or valuable spaces.

Guide prices reviewed October 2026. Starting figures assume a straightforward project and exclude VAT. Survey findings, design, structure, specification, access and the final scope determine the written quotation.
Planning and heritage in Chelsea
Chelsea falls within the Royal Borough of Kensington and Chelsea. Much of the area is covered by conservation designations, including Chelsea, Cheyne, Royal Hospital and neighbouring character areas. Listed status, conservation controls and Article 4 Directions can restrict changes that might be straightforward elsewhere, including windows, roof alterations, façades and external details.
The planning position must be checked against the individual address. Internal work may also require listed building consent where a property is listed. Planning approval, listed building consent, freeholder consent and building regulations are separate processes, and more than one may apply.

Questions about building in Chelsea
Do you work in listed or conservation-area properties in Chelsea?
We take on enquiries where the correct design information and permissions are in place. Listed building consent may be required for internal as well as external changes, so the address and scope should be checked by the appropriate planning professional.
Can you manage renovation work in a Chelsea mansion block?
Yes, subject to the building’s rules and approvals. Access, lifts, common-area protection, working hours, waste removal, fire separation and service connections should be agreed before the programme starts.
Do you provide bespoke joinery for Chelsea homes?
Yes. Prohaus builds wardrobes, shelving, media units, benches and other fitted storage to suit the room, including awkward alcoves and sloping ceilings.
How much does building work cost in Chelsea?
Guide prices start from £60,000 plus VAT for a rear or side extension, £50,000 plus VAT for a loft conversion, £4,500 plus VAT for a kitchen or bathroom, £100,000 plus VAT for a larger renovation or conversion, and £1,200 plus VAT for bespoke joinery. The final quotation depends on the surveyed property, drawings, structure, specification, access and agreed scope.
How long will my project take?
Timing depends on the scope, approvals, structural work, specification, access and whether the property remains occupied. We set out a realistic programme once the design information and scope are clear, rather than promising a generic duration before the project has been assessed.
Who provides gas and electrical certification?
Where gas or notifiable electrical work forms part of the project, it is carried out by appropriately registered subcontractors, who provide the relevant certification for their work.
What contract and guarantee do you provide?
Every project runs under a written, agreed contract. Completed Prohaus work comes with a 1-year guarantee, with the scope and any product-specific warranties recorded in the project documents.
