Kitchen Extension Ideas for West London Homes
Victorian and Edwardian terrace layouts
Side return layouts can transform narrow kitchens in Chiswick, Acton and Ealing by adding width, roof lights and a cleaner route to the garden.
Open-plan kitchen living spaces
Rear and wrap-around extensions can combine cooking, dining and relaxed seating into one connected room with large glazed openings.
Kitchen islands, utility zones and storage
We plan island size, circulation, appliance positions, utility storage, lighting and worktop details before the build reaches the finishing stage.
Bi-fold or sliding doors and garden connection
Full-height glazing helps create a bright kitchen diner, but it also needs proper structural design, insulation, drainage and ventilation planning.

Planning Permission and Building Regulations in West London
West London homes need postcode-specific planning checks. Some single-storey rear and side extensions may fall under permitted development, but conservation areas, flats, maisonettes, Article 4 restrictions and larger proposals often need extra planning detail.
Useful official guidance: Planning Portal extension guidance, prior approval guidance, Lawful Development Certificates, GOV.UK party wall guidance.
- Permitted development: some householder extensions may qualify, but size, height, boundaries, previous extensions and property type must be checked.
- Larger rear extensions: prior approval may apply to some single-storey rear extensions, depending on the proposal and neighbour consultation.
- Conservation areas: Ealing, Hammersmith & Fulham, Hounslow and Hillingdon include planning-sensitive areas where materials, roof form and glazing may need extra care.
- Building Regulations: structure, drainage, insulation, ventilation, electrics, fire safety and glazing performance must be compliant before completion.

FAQs
FAQs About Kitchen Extensions in West London
Do I need planning permission for a kitchen extension in West London?
Some kitchen extensions can be built under permitted development, but many projects need planning permission, especially wrap-around extensions, flats, maisonettes, conservation-area homes and larger proposals.
Does a kitchen extension fall under permitted development?
Some householder rear or side extensions may qualify if they meet strict limits on size, height, boundaries, materials and previous extensions. A Lawful Development Certificate can help confirm the route.
What is the difference between a side return and a wrap-around kitchen extension?
A side return extension uses the narrow side passage beside the existing kitchen. A wrap-around extension combines side and rear space to create a larger open-plan kitchen diner.
How much does a kitchen extension cost in West London?
Many projects fall between £70,000 and £220,000+ depending on size, structure, access, glazing, drainage, kitchen specification, worktops and finish level.
How long does a kitchen extension take from survey to completion?
The full process can take several months including survey, design, planning, structural calculations, party wall matters and construction. Site duration depends on project size and specification.
Can I stay in my home while the extension is being built?
Often yes, but it depends on kitchen downtime, services, dust control, access, safety and whether temporary cooking arrangements are practical.
Do I need a party wall agreement for my kitchen extension?
Many terraced and semi-detached homes need party wall notices where work affects shared walls, boundaries, excavation near neighbours or structural openings.
What areas of West London do you cover?
We cover Ealing, Chiswick, Acton, West Ealing, Hanwell, Hammersmith, Fulham, Shepherd's Bush, Brentford, Isleworth, Hounslow, Hillingdon and nearby areas.

Will a kitchen extension add value to my home?
A well-designed kitchen extension can improve usable space, natural light and buyer appeal, but value depends on the property, location, design quality and final finish.
