Absolutely transformed our Victorian terrace in Hampstead. The attention to period detail was exceptional. They restored our original cornices and installed a stunning new kitchen. Highly recommend for anyone with a period property.

Sarah M.

Hampstead, NW3

Had our entire house rewired by HAMPSTEAD RENOVATIONS. Clean, professional work with minimal disruption. They were careful around our period features and the plastering afterwards was perfect.

James R.

Belsize Park, NW3

Emergency boiler repair on a Sunday - arrived within an hour and fixed the issue quickly. Fair pricing and no callout fee gouging. Will definitely use again.

Decision framework

Refurbish or Rebuild: Choosing the Right Approach in Chiswick

The biggest single decision on a bathroom renovation project is whether to refurbish the existing property or demolish and rebuild. Here's how we frame the trade-offs for Chiswick owners.

1How much of the existing structure is sound?

Refurbish

Most Chiswick 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.

2What does the planning landscape allow?

Refurbish

Conservation areas in Chiswick 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.

3How does the budget compare?

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.

4What is the energy and comfort upgrade gap?

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.

5What about resale value and marketability?

Refurbish

Refurbished Chiswick 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

Sequencing Your Bathroom Renovation Project

An 18-week bathroom renovation project breaks into 8 phases, each with specific trades, deliverables, and risks. Understanding the sequence helps you anticipate questions, decisions, and on-site moments.

Phase 1: Pre-construction

Weeks -8 to -2

Trades on site

Architect Structural engineer Surveyor Project manager

Deliverables

  • Full survey including drains, services, and structural integrity
  • Detailed design package with specifications and material schedule
  • Planning permission and Building Control submissions where required
  • Party Wall agreements coordinated with neighbours
  • Fixed-price contract with itemised quote

Risk note

Hidden defects (damp, asbestos, non-compliant additions) are usually discovered here — budget a 10% contingency.

Phase 2: Site setup & strip-out

Weeks 1 – 2

Trades on site

Site manager Strip-out crew Skip and waste contractors

Deliverables

  • Site protection: dust screens, floor coverings, scaffold
  • Strip-out of all existing finishes, fittings, and services
  • Confirmation of structural condition once exposed
  • Asbestos survey and remediation if pre-1999 property
  • Final scope confirmation with client

Risk note

Strip-out always reveals more than the survey predicted. Quick decision-making protects programme.

Phase 3: Structural works

Weeks 2 – 5

Trades on site

Structural engineer Steel fixers Bricklayers Carpenters

Deliverables

  • Steel beams, posts, and lintels installed per engineer's design
  • Wall removals, openings, and structural alterations
  • Foundation works for new walls or extensions
  • New floor structures and joist work where required
  • Building Control structural inspection and sign-off

Risk note

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

Phase 4: First-fix services

Weeks 5 – 8

Trades on site

Electricians Plumbers Heating engineers Insulation contractors

Deliverables

  • Full rewire to 18th edition standards with NICEIC certification
  • New plumbing in PEX or copper with manifolds
  • Heating system installation: boiler, cylinder, MVHR if specified
  • Insulation to walls, floors, and roof
  • First-fix for AV, smart home, security, and data

Risk note

First-fix sequencing matters: services must be coordinated to avoid clashes before plastering.

Phase 5: Plastering & flooring substrate

Weeks 8 – 11

Trades on site

Plasterers Floor screeders Carpenters Tilers (substrate)

Deliverables

  • Full skim plastering throughout
  • Floor screeding with underfloor heating where specified
  • Internal stud walls, ceilings, and architectural detailing
  • Window and door reveals finished
  • Subfloor preparation for finished flooring

Risk note

Plaster needs proper drying time (1 week per coat) — rushing this stage risks cracking and finish defects.

Phase 6: Second-fix services

Weeks 11 – 13

Trades on site

Electricians Plumbers Heating engineers AV installers

Deliverables

  • All sockets, switches, and lighting fittings installed
  • Sanitaryware, taps, showers, and radiators connected
  • Boiler commissioning and heating zoning configured
  • Smart home, AV, and security systems commissioned
  • Building Control electrical inspection

Risk note

Specification of fittings should be locked before week 8 to avoid lead-time delays.

Phase 7: Joinery, kitchens & bathrooms

Weeks 13 – 16

Trades on site

Bespoke joiners Kitchen fitters Stone fitters Tilers

Deliverables

  • Bespoke joinery installation: wardrobes, media walls, pantries
  • Kitchen units, worktops, splashbacks, and appliances fitted
  • Bathroom tiling, sanitaryware, and shower screens
  • Internal doors, architraves, and skirting installed
  • Stair restoration or replacement completed

Risk note

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

Phase 8: Finishing & handover

Weeks 16 – 18

Trades on site

Decorators Floor finishers Cleaners Snagging team

Deliverables

  • Decoration: full mist coat, undercoat, two top coats
  • Floor finishes laid: engineered timber, stone, or carpet
  • Final clean and snagging walkthrough
  • Building Control sign-off and warranty paperwork
  • Handover pack with manuals, certificates, and aftercare schedule

Risk note

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