Covering Hertfordshire

We cover Hertfordshire, including Watford, Hemel Hempstead, Stevenage and St Albans, and the towns around them.

Homes in the East of England

The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.

What is a house-to-flat conversion?

A house-to-flat conversion divides a single house into two or more self-contained flats, each with its own front door, kitchen and bathroom. It always needs planning permission and full building regulations approval, particularly for fire separation and sound insulation between flats.

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.

How long does a conversion take?

Typically 16 to 30 weeks on site after approvals.

Who deals with the council for a project in Hertfordshire?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
