House extensions in Tooting Broadway

Tooting Broadway sits in Wandsworth, where the streets are dominated by converted period houses and maisonettes where structural and access sequencing matters. The build that pays back most reliably here is a rear extension paired with a loft dormer, done under one scaffold and one contract.

What we build in Tooting Broadway

Most Tooting Broadway projects we scope fall into three buckets: a side-return or rear infill that fixes a dark galley kitchen, a full-width rear extension that opens the ground floor to the garden, and a rear-plus-loft package that adds a bedroom while the scaffold is already up. Victorian and Edwardian terraces at scale — Tooting, Balham and Battersea are the classic side-return heartland.

Planning permission in Tooting Broadway

Wandsworth has published clear extension SPDs and is one of the more predictable planning boroughs. Conservation zones (Nightingale, Battersea Park) tighten design review.

Before you assume permitted development applies to your street, check whether your street falls inside a conservation area or an Article 4 direction — both are common in Wandsworth and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.

Party wall and neighbours

Two party wall Awards on almost every terrace project.

Serve notice at least two months before you break ground. Budget £1,200–£2,400 per adjoining owner if they dissent and appoint their own surveyor — see the Party Wall Act guide.

Access, logistics and site set-up

Access is typically through the house, so expect dust protection, a boarded route and a skip permit from the council.

Every quote we issue for Tooting Broadway prices skip permits, parking suspensions, protection and welfare explicitly in the preliminaries — so the number you sign is the number you pay.
