House Extensions Holland Park

Check what has been left out before deciding. Cheap house extensions quotations in Holland Park tend to be rather light on approvals and reinstatement, and work started without Royal Borough of Kensington and Chelsea sign-off becomes expensive when the W11 property is sold. GS Renovation includes both as standard. We would rather lose the job than win it by omission. Ring 07472 424 226 and GS Renovation will explain what a complete Kensington and Chelsea quotation should contain, and what it should not. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

That depends on how booked we are, and you will get a straight answer rather than a comfortable one. GS Renovation usually schedules house extensions a few weeks ahead for Holland Park homes, and getting the W11 survey done early is what secures a slot. Where Royal Borough of Kensington and Chelsea approval is needed the application runs in parallel. Ring 07472 424 226 for current availability across Kensington and Chelsea. Email info@gsrenovationltd.co.uk with the W11 address and we will book a survey.

Yes. We are rated 4.9 from 31 reviews on MyBuilder, all public and written by the homeowners themselves. The work behind them is the same house extensions we would carry out at your W11 address, on similar Edwardian bay-fronted houses with generous ceiling heights and long rear gardens across Kensington and Chelsea. GS Renovation will also give you addresses of finished Holland Park projects. Seeing one in person is worth more than reading about it. Ring 07472 424 226 to arrange that. The Kensington and Chelsea rating covers work of exactly this kind.

Usually, if you are excavating near a neighbour's foundations or building on the line of junction, both common on Holland Park plots. Notice is served before work starts and a schedule of condition protects both parties. We prepare the paperwork for your W11 address.

Carefully, and in a defined order. We survey the W11 property, confirm what the structure is doing, appoint an engineer where house extensions require a design, then prop, remove and support in sequence. GS Renovation agrees with the Holland Park homeowner beforehand which original features are being protected. Royal Borough of Kensington and Chelsea inspects before anything is concealed. GS Renovation will set out the whole house extensions sequence planned for your W11 home in Holland Park before anything at all starts.

Possibly. Some single storey rear extensions are permitted development, but Holland Park falls within the Royal Borough of Kensington and Chelsea and its conservation controls, so permitted development rights are often restricted and a planning application to the council may be required. We check your specific property first, then handle the correct application along with the building regulations for the structure.

Every postcode in the area, and most of those around it. House extensions work takes GS Renovation across Holland Park, Kensington and the wider Central London in a normal month, so a W11 property is routine. Building control goes through Royal Borough of Kensington and Chelsea in the usual way. Email info@gsrenovationltd.co.uk and we will book a visit. Nothing is owed for the survey or the quotation. The written quotation normally follows that visit within a few working days.
