Architects who know Chiswick

Chiswick falls mainly within the London Borough of Hounslow, with parts of Bedford Park in the London Borough of Ealing. Much of the area is covered by conservation areas, and some streets have Article 4 directions that remove permitted development rights. Work that would be straightforward elsewhere, such as replacing windows, adding a dormer or changing a front boundary, can need planning permission here. We work regularly in W4 and know these constraints first-hand.

Conservation areas and local character we work with include Bedford Park, Strand on the Green, Old Chiswick and Chiswick Mall, and Turnham Green. In these streets, the success of an application depends on getting the details right: rooflines, window proportions, materials and the way a rear extension sits against its neighbours. We prepare drawings, heritage statements and design and access statements that planning officers can say yes to.

What we do in Chiswick

How a project works

  1. Free 30-minute call: we discuss your brief, budget and timescale.
  2. Site visit and feasibility: what is possible under permitted development or planning, and any heritage constraints.
  3. Design and planning: options, 3D visuals, then the planning or listed building consent application.
  4. Technical design: building regulations drawings, structural coordination and specifications for tender.
  5. On site: contract administration and site visits so the build matches the design and specification.

Why clients choose us

We are a RIBA Chartered Practice with a background that few residential architects have: heritage projects on listed palazzi in Milan and Florence, and design management for a main contractor in London. That means designs that get approved and are practical to build. Clients regularly mention our clear communication and our site checks on things like insulation specification, which protect the quality of the finished work.

We also work across neighbouring areas, including Hammersmith, Kensington, Ealing, Brentford, Barnes and Twickenham.

Frequently asked questions

Do I need planning permission for an extension in Chiswick?

Often yes. Much of Chiswick sits in conservation areas and some streets have Article 4 directions that remove permitted development rights, so many extensions, dormers and window changes need planning permission. We check your property's status at the first call.

Do you work in Chiswick?

Yes. LP ARKinnovation works regularly in Chiswick and across West London, so we can visit sites quickly and know the local planning context in Hounslow and Ealing.

Do you also do interior design?

Yes. We design interiors, joinery and material palettes alongside the architecture, so the house works as one coherent project.
