Garage conversions in Lancashire

Covering Lancashire

We cover Lancashire, including Preston, Burnley, Blackburn and Blackpool, and the towns around them.

Homes in the North West

The North West has long rows of Victorian terraced houses in its towns and cities, alongside inter-war semis and post-war estates, so rear extensions, dormer lofts and kitchen extensions are common projects.

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.

How is a garage conversion approved in Lancashire?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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.

What can change the price or programme?

The garage floor is often lower than the house and needs raising.
Losing a parking space can matter on streets with permit parking.
