House-to-flat conversions in Stevenage

Covering Stevenage

We work in Stevenage (SG1) and the places around it, including Hitchin, Letchworth Garden City and Welwyn Garden City.

Homes in the East of England

Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.

What is included in a house-to-flat conversion in Stevenage?

We assess the house against the council’s policies on flat sizes, parking, bins and cycle storage before any design work, then design layouts to the space standards your council uses. On site the critical work is fire separation, sound insulation between floors, separate services and meters, and protected escape routes.

Priced on survey.

Do you need permission for a house-to-flat conversion in Stevenage?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

Dividing a house into flats always needs planning permission in England. Councils assess flat sizes (many use the nationally described space standard), parking, bins, cycle storage and the effect on family housing supply.

What can change the price or programme?

Each flat needs its own utilities and metering.
Mortgage lenders and freehold arrangements need early legal advice.

What people ask before starting

Does converting a house into flats need planning permission?

Yes, always. Subdividing a house into flats is development under planning law.

Can you help with the planning case?

Yes. We check the council’s policies first and only proceed with a design that has a realistic chance of approval.

Can you visit a house in Stevenage to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
