Question 1

What does it cost to fully renovate an Edwardian semi in Streatham (SW16)?

Accepted Answer

A large-scale renovation of one of the bigger SW16 Edwardian semis — a rear extension, hip-to-gable loft conversion, complete kitchen, bathrooms, full rewire and replumb, plastering, flooring and decoration through every room — generally runs between £235,000 and £400,000. Floor area and extension depth are the main drivers; the specification of kitchen and bathrooms and whether structural steelwork is extensive also affect the final figure. Party-wall notices are required for the semi-detached arrangement with the adjoining owner. The quote breaks down each trade and phase as a separate line, returned the same day as the site visit.

Question 2

Do loft conversions on Streatham Edwardian semis need planning permission (SW16)?

Accepted Answer

Hip-to-gable loft conversions on SW16 semi-detached houses generally fall within permitted development under the 50-cubic-metre allowance for non-terraced properties — most Streatham semis sit comfortably within it when the loft volume is calculated. A rear dormer and rooflight additions are also usually PD on these houses. The exception is any address near Lambeth's conservation pockets around the High Road, where external alterations attract additional planning scrutiny. We check the specific designation for your SW16 address at the survey and confirm the approval route before any design or structural costs are committed.

Question 3

Is the renovation potential different on the Victorian terraces near Tulse Hill compared to the Edwardian semis?

Accepted Answer

Yes, noticeably. The Victorian terraces in the Tulse Hill and Streatham Park corners of SW16 are typically narrower with less garden depth, which makes a large combined rear extension and loft less common. The frequent brief on these houses is a single-storey rear extension to open the kitchen, a bathroom overhaul, or a loft conversion planned as a standalone phase. The Edwardian semis further up toward Streatham Common are a different proposition — larger across every dimension and suited to the whole-house renovation scope that combines all three. Both markets sit well within the area we cover from our south London base.
