Outstanding work on our West Derby double-storey extension. Seamless project from design and planning to completion. The new kitchen-diner and upstairs bedroom are fantastic.

Liverpool House Extensions – FAQ

Key questions about planning, cost and timelines

Do you handle planning permission and drawings?

Yes. We provide surveys, concept design, architectural drawings and submit planning applications to Liverpool City Council. We also manage building control and structural calculations.

What’s the typical timeline for an extension?

Single-storey 6–10 weeks, double-storey 10–16 weeks, wrap-around 12–18 weeks. Times vary with size, weather and specification. You’ll receive a detailed programme.

Will I need a Party Wall Agreement?

Many terrace and semi-detached projects require Party Wall notices. We guide you through notices, awards and timings to avoid delays.

Can you extend in conservation areas?

Yes, with heritage-sensitive design and materials. We coordinate with conservation officers to achieve approvals while respecting local character.
