Premium House Extensions in South London
South London homes often need more space, more natural light and a layout that works better for modern family life, especially where period layouts, conservation areas, party walls and tight garden plots shape what is possible.
We create bespoke house extensions across South London for homeowners who want a refined, practical and beautifully finished result. From Victorian and Edwardian terraces to 1930s semis and larger family houses, each project is planned around the property, the borough planning route and the way the new space will be used every day.
Our design and build approach keeps the process joined up, covering early feasibility, planning advice, structural coordination, construction and finishing. The result is a calmer route from first idea to completed extension.

Extension Types for South London Homes
Every property needs the right layout. We help you choose the extension type that best fits your home, budget, planning position and long-term plans.
Rear Extensions South London
Extend into the garden to add depth, improve flow and connect the original house to a modern open-plan living space.
Side Return Extensions South London
Use the narrow side return of a period terrace to add valuable width, natural light and a more generous kitchen layout.

Combine side and rear space for a larger transformation, ideal for homeowners wanting a more dramatic open-plan ground floor.
Local design knowledge
Designed for South London Period and Family Homes
South London includes a rich mix of property types, from Victorian terraces in Clapham, Battersea and East Dulwich to Edwardian homes in Dulwich, family houses in Wimbledon, Wandsworth and Streatham, and larger plots across Bromley, Merton and Croydon.
We design extensions that respect the original building while creating the space modern homeowners want: larger kitchens, better garden connection, more daylight, clean glazing lines and interiors that feel calm, warm and practical.

Costs, Planning and Timelines for South London House Extensions

What affects extension cost?
Size, foundations, steelwork, rooflights, sliding doors, kitchen specification, finishes, drainage, access and professional design work all affect the final cost.

South London House Extensions FAQs
Do I need planning permission for a house extension in South London?
Some house extensions can be built under permitted development, but planning permission may be needed depending on size, height, design, previous extensions, conservation-area status and the type of property. We check the planning route before advising.
Are rear and side return extensions permitted development in South London?
They can be in some cases, but the rules depend on depth, height, materials, neighbouring boundaries and whether the property has permitted development rights. Side returns and wraparound layouts often need careful assessment.
How much does a house extension cost in South London?
Cost depends on size, structure, glazing, kitchen specification, finishes, access and planning requirements. After reviewing your property, we can advise on likely scope and provide a clearer quotation route.
What is the best extension type for a Victorian or Edwardian terrace?
Side return, rear and wraparound extensions are often strong options. The best choice depends on the original layout, garden depth, planning limits and whether you want more width, more depth or a complete open-plan transformation.
Can you create an open-plan kitchen extension with rooflights?
Yes. Many South London projects focus on creating a bright kitchen, dining and family space with rooflights, sliding doors, structural openings and a better connection to the garden.
How long does a South London extension take from design to completion?
Timescales vary by planning route, design complexity and build scope. Projects requiring planning approval, party wall notices or complex structural work usually need more time before construction starts.
Can I stay in my home during the build?
In many cases, yes, but it depends on the scale of work, access, services, kitchen disruption and health and safety. We discuss this before the build so you can plan properly.
Do you handle architectural design, planning and construction?
Yes. We provide a joined-up design and build service covering design guidance, planning support, Building Regulations coordination, structural calculations, construction and project management.
What South London areas do you cover?
We cover South London areas including Clapham, Battersea, Wandsworth, Wimbledon, Dulwich, East Dulwich, Peckham, Southwark, Lambeth, Streatham, Balham, Lewisham, Bromley, Merton, Croydon and surrounding neighbourhoods.
