Read articleThese are the service families that usually perform best across Chelsea because they map well to the local housing stock, planning context, and client demand.
High-quality renovation pages need to explain not just what gets upgraded, but how layout, services, finishes, and compliance are sequenced for this type of home.
Kitchen pages should explain layout, storage, extraction, electrics, and appliance planning rather than treating the work as a simple cabinet swap.
Bathroom pages should cover waterproofing, drainage, ventilation, and layout efficiency so the room works well long after the tiles go on.
The strongest area pages are not just service lists. They explain what the local housing stock looks like, which approvals matter, how access affects programme planning, and where premium briefs usually change shape before work starts.
Planning applications are usually handled via London Borough of Kensington and Chelsea.
These editorial hub pages add planning context, property insight, and best-matched service links for the strongest neighborhoods inside Chelsea.

Decision framework
The biggest single decision on a house extensions project is whether to refurbish the existing property or demolish and rebuild. Here's how we frame the trade-offs for Chelsea owners.
Refurbish
Most Chelsea period homes have sound brick, timber, and roof structures that are worth retaining. Refurbishment preserves character and avoids planning risk.
Rebuild
If the existing structure has serious subsidence, fire damage, or non-compliant additions, demolition and rebuild may be the cleaner route.
Our recommendation
Refurbish unless a structural engineer flags major issues at survey.
Refurbish
Conservation areas in Chelsea typically restrict demolition. Refurbishment, with permitted-development additions, is usually faster to consent.
Rebuild
New-build replacement requires full planning consent and often an environmental impact assessment. Listed buildings rule out rebuild entirely.
Our recommendation
Refurbish for almost all conservation-area and listed properties.
Refurbish
Refurbishment costs typically £1,200 – £2,500 per sqm for premium spec, with shorter programmes and lower professional fees.
Rebuild
New-build costs £3,000 – £5,000+ per sqm in prime London, plus 18-30 months of design, planning, and demolition costs.
Our recommendation
Refurbish for £1m – £3m budgets; rebuild only justified above £3m on the right plot.
Refurbish
Internal wall insulation, MVHR, and slim-double-glazed sashes can lift period homes to EPC C/B without altering external appearance.
Rebuild
New-build can hit EPC A and Passivhaus standards with mechanical ventilation, triple glazing, and air-tight detailing.
Our recommendation
Refurbishment usually closes the comfort gap at lower cost in period properties.
Refurbish
Refurbished Chelsea period homes command a premium for character. Buyers in this market value original features.
Rebuild
New-build replacements in period streets can struggle to match comparable refurbished sale values.
Our recommendation
Refurbish if your property has period character. Rebuild only on plots without heritage value.
How we sequence the build
An 18-week house extensions project breaks into 8 phases, each with specific trades, deliverables, and risks. Understanding the sequence helps you anticipate questions, decisions, and on-site moments.

Deliverables
Risk note
Hidden defects (damp, asbestos, non-compliant additions) are usually discovered here — budget a 10% contingency.
Trades on site
Deliverables
Risk note
Strip-out always reveals more than the survey predicted. Quick decision-making protects programme.

Deliverables
Risk note
Steel fabrication lead times can run 4-6 weeks — order early to avoid programme delay.

Deliverables
Risk note
First-fix sequencing matters: services must be coordinated to avoid clashes before plastering.
Trades on site
Deliverables
Risk note
Plaster needs proper drying time (1 week per coat) — rushing this stage risks cracking and finish defects.
Trades on site
Deliverables
Risk note
Specification of fittings should be locked before week 8 to avoid lead-time delays.

Risk note
Stone worktops require templating after units are installed — adds 2 weeks lead time.

Risk note
Final 5% of works always takes 20% of effort. Defect-free handover requires methodical snagging.

£95,000 – £125,000

£235,000 – £275,000
