Premium Design & Build House Extensions in West London

West London homes often combine period character with the need for more practical modern space. A carefully designed extension can create a brighter kitchen, a better family layout and a stronger connection to the garden without losing the original character of the home.

We design and build bespoke house extensions across West London, including Ealing, Acton, Chiswick, Hammersmith, Fulham and surrounding areas. Our approach suits Victorian and Edwardian homes, family houses and properties where planning, access, structure and finish quality need to be handled properly from the beginning.

From the first consultation through to design, approvals, construction and handover, we keep the route clear, practical and premium.

  • Bespoke rear, kitchen, side return and wraparound extensions
  • Open-plan living with skylights, rooflights and large glazing
  • Planning permission, Building Regulations and structural support
  • Clear project management and premium finishing

Local expertise

Designed for West London Period and Family Homes

West London extension projects often involve period houses, conservation-sensitive streets, party wall considerations and homes where the new addition must feel carefully integrated rather than simply added on.

We plan each project around the property type, the garden, the roof design, the natural light strategy and the planning route. Whether you are extending a home in Ealing, Acton, Chiswick, Hammersmith, Fulham or nearby, the goal is the same: a refined extension that improves the way the whole house works.

  • Rear kitchen and family room extensions
  • Side return and wraparound layouts
  • Skylights, rooflights, sliding doors and open-plan interiors

Cost and process

West London Extension Costs, Planning and Timeline

Extension costs depend on size, structural complexity, glazing, finishes, access, professional requirements and the planning route. We give practical guidance early so you can understand the likely scope before committing.

How much does a West London extension cost?

Small infill or side-return projects may start from a lower budget, while larger rear and wraparound extensions usually require more investment. Specification, structure and finishes make a major difference.

Planning permission and Building Regulations

Some single-storey extensions may fall under permitted development, but larger, wraparound or multi-storey projects often need planning permission and full Building Regulations approval.

Typical build timeline

Many extensions take several months from design through approvals and construction. The exact programme depends on planning, structure, access and finish level.

Maximising natural light

Skylights, rooflights, roof lanterns and large glazed doors can transform darker period layouts into bright, usable spaces.

Questions homeowners ask

West London House Extensions FAQs

How long will my house extension take?

Timescales depend on design, planning route, structural complexity and finish level. Many projects take several months from initial design through approvals and construction, with the on-site build depending on the size and specification.

Will an extension add value to my West London home?

A well-designed extension can improve living space and increase market appeal, especially where it creates a larger kitchen, better garden connection and a more practical family layout.

Do I need planning permission or Building Regulations approval?

Some single-storey extensions may be possible under permitted development, but larger rear, side, wraparound or double-storey projects may need planning permission. Building Regulations approval is usually required for structural and safety compliance.

Can I stay in my home during construction?

Often yes, but it depends on the scale of work, kitchen disruption, services, access and health and safety. We discuss this before the build so you can plan properly.

How do I maximise natural light in my extension?

Skylights, rooflights, roof lanterns, large sliding doors and carefully placed glazing can bring light deep into the plan and make the extension feel much larger.

How much will my West London extension cost?

Cost depends on size, structure, glazing, finishes, access and approvals. We provide a tailored quotation after reviewing your property and preferred extension type.

Why choose a specialist West London extension builder?

West London homes often involve period details, planning sensitivity, party wall matters and access constraints. A specialist builder can plan these issues earlier and reduce risk during the build.

What warranty or aftercare do you offer?

We focus on long-term build quality, clear handover and aftercare support. Any warranty or guarantee details can be confirmed with your project quotation and contract documentation.
