Common Questions
Frequently Asked Questions
Do I need planning permission for a house extension?
Not always. Many Rear Extensions fall under Permitted Development (PD) rights, but you will need Full Planning Permission if you are in a Conservation Area or if the extension exceeds PD volume/depth limits (e.g., 3m/4m deep).
How long does a typical London house extension take to build?
A standard Side Return Extension or single-storey rear extension typically takes between 16 and 24 weeks from breaking ground to final completion, depending on structural complexity and finishes.
When do I need a Party Wall Agreement for my London extension?
You need a Party Wall Agreement if your extension involves digging foundations within 3m of your neighbour's structure or if you build up to the boundary line, which is standard practice for most London side return and rear extensions.
What is the most value-adding extension type in London?
The Wrap-Around Extension (combining rear and side return) often adds the most value in London, as it creates a large, L-shaped open-plan kitchen/living area, which is the most sought-after feature for buyers.
What is the maximum depth allowed for a London rear extension under PD?
For a single-storey rear extension under PD, the maximum depth allowed is 3 meters for terraced/semi-detached houses, or 4 meters for detached houses. Deeper extensions usually require full Planning Permission.
