What do you get with a house-to-flat conversion?

From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Your questions answered
How much does a flat conversion cost?
It varies too much to give a reliable guide figure, so we price each one on survey. The reduced 5% VAT rate can apply where the number of dwellings changes.
What are the main building regulations issues?
Fire separation between flats, protected escape routes, sound insulation and separate services.
Who deals with the council for a project in Darwen?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
