High-Spec Refurbishment

What makes Chelsea refurbishment work different.

Chelsea projects often sit within conservation areas, with strict planning controls, party wall considerations and a high bar for finish quality expected by residents, freeholders and managing agents in one of London's most closely regulated boroughs.

Bayocorp brings structure to these projects early, coordinating consultants, building control and specialist trades so that scope, programme and cost stay aligned from the outset.

Local Considerations

Meeting Chelsea's standard for planning and finish.

Almost the entire Royal Borough of Kensington and Chelsea, including Chelsea itself, sits within conservation areas, and the council is known for some of the most rigorous planning enforcement in the country. Basement extensions in particular are subject to a specific council policy introduced after a series of disputes over subterranean development, and even straightforward internal changes to a listed property usually need consent before work can start.

Mews properties, garden squares and terraced townhouses sit close together across Chelsea, so party wall agreements are routine, and the borough's higher finish expectations mean specification decisions carry more weight than in many other areas.

✓ A specific council policy governs basement extensions following past disputes
✓ Listed building consent is common, even for internal changes to period properties
✓ Higher finish expectations mean specification decisions need more careful planning upfront

Our Process

How Bayocorp delivers to Chelsea's standard.

Consent & Policy Review

We establish listed building status, conservation constraints, and whether the council's basement extension policy applies, before pricing anything, since these directly shape what's achievable.

Planning & Listed Building Consent

Applications are prepared and managed directly with the Royal Borough of Kensington and Chelsea, with the programme built around a realistic approval timeline.

Specification & Sequencing

Specification is locked to the finish standard the area expects, and trades are sequenced around party wall notices and mews or square access constraints.

Delivery & Handover

Hands-on site management, weekly updates and full handover documentation to match Chelsea's higher finish expectations.

What To Budget

Indicative costs for Chelsea projects.

Chelsea's finish expectations and listed building consent requirements mean costs typically sit well above borough-wide averages, and basement or below-ground work carries its own separate cost and consent process.

£12,000-£25,000Bathroom Refurbishment

£25,000-£55,000Kitchen Renovation

£70,000-£140,000Full Flat / Mews Refurbishment

£70,000-£150,000Extension (excl. basement)

£150,000-£400,000+Full House Refurbishment

These are indicative starting points based on comparable Bayocorp projects. A fixed price follows a site visit, survey and full scope review.

Common Questions

Chelsea refurbishment questions we hear often.

Will I need listed building consent in Chelsea?

Given the near-total conservation area coverage across the Royal Borough of Kensington and Chelsea, this is common, even for internal changes to a listed property. We confirm this for your specific address before pricing.

Is a basement extension possible in Chelsea?

It's subject to a specific council policy introduced after a series of past disputes over subterranean development, so basement projects need their own dedicated planning and structural process, which we scope and manage separately from above-ground work.

What should I expect from the finish standard?

Chelsea's higher finish expectations mean specification decisions carry more weight than in many other areas, so we lock specification early and plan trades around the standard the area expects, not a generic finish.

Does Bayocorp only work on very high-end Chelsea projects?

No. We take on projects across a range of scopes and budgets within Chelsea, from bathroom and kitchen refurbishments through to full house renovations, always built around the area's finish and consent expectations.

How early should I involve Bayocorp in a Chelsea project?

As early as possible, ideally before finalising a design, since listed building consent and conservation requirements in Chelsea can shape what's realistically achievable, and early input avoids costly redesigns later.
