Garage conversions in Sevenoaks

Covering Sevenoaks

We work in Sevenoaks (TN13) and the places around it, including Tonbridge, Swanley and Tunbridge Wells.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

What does a garage conversion involve?

A garage conversion turns an attached, integral or detached garage into a habitable room by infilling the door opening, insulating the floor, walls and roof, and adding windows, heating and power. It is one of the quickest and cheapest ways to add a room.

Planning and building rules in Sevenoaks

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.

An internal garage conversion is usually permitted development in England unless the house is listed, an Article 4 direction applies, or it is on an estate where the planning permission removed permitted development rights. We check the original permission for your house.

What should I think about before starting?

Some new-build estates have a planning condition keeping garages for parking.
The garage floor is often lower than the house and needs raising.
