NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle planning applications and appeals in South London SW and SE. Fees are priced per project by our own quantity surveyor, from the actual scope. Call 020 7731 6841, and a budget estimate typically follows within seven days.
South London spans several councils. Lambeth, Wandsworth, Southwark and Merton each keep their own plan.
We confirm the borough, then check for a conservation area or listing. That decides whether permitted development is even available.
Many rear extensions go through prior approval rather than a full application. Basements and dormers in conservation areas need full consent.
After approval, the conditions are cleared before site starts. Party wall notices go out from the same drawings.
What Lambeth looks for.
- Council
- London Borough of Lambeth, under its Local Plan adopted in September 2021.
- Policy Q11
- Extensions are supported in principle, if they stay subordinate to the house.
- Permitted development
- A single-storey rear extension can reach 3 metres on a terrace without planning. Prior approval can allow 6.
- Front lightwells
- Only where needed for daylight. In conservation areas, grilles rather than open areas are likely.
- After consent
- Conditions are checked before site starts. Party wall notices and building control follow from the same drawings.
- Wandsworth side
- Near Clapham Junction, Wandsworth’s Policy LP5 applies instead. We confirm the borough first.

Which council handles planning in South London?
It depends on the street. Clapham is mostly Lambeth.
Battersea is Wandsworth, Dulwich is Southwark and Wimbledon is Merton.
What is prior approval for a Lambeth extension?
A lighter route for a terrace’s single storey rear extension, up to six metres.
Neighbours are consulted, and it is not open in a conservation area.
Does a front lightwell need planning in Lambeth?
Yes, as part of the basement application.
In conservation areas, a grille is more likely than an open area.
How long does a South London planning application take?
A householder application has an eight week target.
We prepare it fully, so it is valid on day one.
