Builders in Balham, SW12

Balham's Victorian and Edwardian terraces, many around the Heaver Estate and close to Tooting Bec and Clapham Commons, are ideal for families who want more space without moving.

Planning in Balham

Most of Balham is in Wandsworth, while parts east of Balham High Road fall under Lambeth. The two councils have different rules and guidance, so it matters which side of the road you are on. The Heaver Estate is a conservation area, with tighter controls on roof and side extensions.

Balham FAQs

Which council covers my house in Balham?

Most of Balham is Wandsworth, but some streets are in Lambeth. Our Planning & Party Wall Checker asks for your postcode and points you to the right council.

Can I build a mansard loft in Balham?

Often, yes, but it usually needs planning permission, especially in a conservation area.

Should I extend my Balham kitchen or convert the loft first?

Start with the space your household needs most. A kitchen extension changes everyday living space and the connection to the garden, while a loft conversion is usually considered for bedrooms or a bathroom. A whole-house plan can help establish a sensible order.

Can a Balham extension be combined with a whole-house refurbishment?

Yes. Planning the work together allows structural changes, heating, electrics and finishes to be coordinated. The scope and programme should be agreed before work starts, including whether any parts of the house can remain in use.

What should I prepare before requesting a quote for my Balham home?

Share your address, the rooms you want to change and your main priorities. Existing drawings, photographs and any planning decisions are useful if you have them, but you can also contact our team while you are still exploring ideas.

"From the first visit to handover, the team was organised, tidy and honest about costs. Our basement is beautifully finished and completely dry, and our neighbours were kept informed throughout."

"We stripped our Victorian terrace back to the brick and the team handled everything: steelwork, rewiring, joinery, the lot. They restored the original cornicing and the house has never looked better."
