Homes in the South West

The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.

What is included in a garage conversion in Cornwall?

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.

Do you need permission for a garage conversion in Cornwall?

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.
