House Extensions in Holland Park

Updated 8 September 2026

For a Holland Park extension, compare the proposed footprint and openings with the actual boundaries and retained rooms. Address-specific heritage controls and access for building work need resolving before the kitchen or living-space design is committed.

Start with the property address, the existing layout and the work you want to include. Access, service routes and any relevant approvals are checked against that brief.

Developing your house extensions brief

Start with the scope below, then discuss the building-specific decisions for your Holland Park property. For the wider service and specification, read our house extensions guide. Fitted storage and vanity cabinetry can be discussed through the bespoke joinery service.

Resolve the extension before planning the finishes

Begin with the existing plan, intended use of the new space and relationship to neighbouring windows, gardens and boundaries. Check the exact property and proposal with the council; permitted development is not a general allowance for flats or listed buildings.

An extension can affect foundations, drainage, structure, insulation and the transition into the existing house. Investigations and structural design should inform the proposed openings and build sequence before the interior specification is fixed.

Check delivery and excavation access, protection of the occupied house and whether the work engages the Party Wall etc. Act. Planning permission, Building Regulations and any party-wall process are separate requirements. Include the existing rooms that need making good in the quotation.

House Extensions in Holland Park: Questions

Is an extension included in a house refurbishment quotation?

Only if it is expressly included. Extension feasibility, structure, drainage, approvals and construction should be described separately so the scope can be compared accurately.

Does house extensions in Holland Park always need planning permission?

No blanket answer applies. Check the proposed work and exact address with the council. Listed-building consent, planning permission and Building Regulations are separate; for a flat, check the lease and any freeholder consent as well.

How should I prepare the project brief?

List the rooms and items to retain, replace or repair, the preferred finish, access arrangements and any known building restrictions. A written scope makes supplier responsibilities, exclusions and changes easier to assess.

Check the exact address and proposed work against RBKC planning guidance. Listed-building consent concerns changes affecting a listed building’s special character; conservation-area status and Article 4 directions are different controls. The council’s address-level Article 4 list identifies the properties and directions to check.

For a flat, read the lease and alteration-consent requirements with the freeholder or managing agent. Building Regulations apply separately. Where the proposed work falls within the Party Wall etc. Act, follow that process too. None of these approvals substitutes for another.
