Covering Preston
We work in Preston (PR0, PR1, PR11) and the places around it, including Leyland, Chorley and Blackburn.
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 goes into a garage conversion?
Most integral garages already have the walls and roof; what they need is a new insulated floor, an infilled front wall with a window, and heating. We check whether your permitted development rights are intact, handle building control and finish the room ready to use.
- Planning check (some estates remove permitted development rights)
- Building control application
- Heating, electrics and data points

Do you need permission for a garage conversion in Preston?
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.
What can affect a garage conversion?
- Some new-build estates have a planning condition keeping garages for parking.
- The garage floor is often lower than the house and needs raising.
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.
What people ask before starting
Do I need planning permission for a garage conversion?
Usually not if the work is internal and your permitted development rights are intact. Some estates remove those rights, so we check.
Can a garage become a bedroom?
Yes, with insulation, ventilation and an escape window or protected route out.
Can you visit a house in Preston 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.
