Most garages, by their nature, are narrow, have a floor level lower than that of the main house, and are un-insulated. The garage roof will most likely be solid concrete and at a lower level than the first floor. Many have electric/gas meters stored within which need to be relocated. Existing drainage routes should also be checked to ensure there are no primary access points located inside the garage.
The process involves;
Check whether you need planning permission
Check the purse
Think design with a Chartered Engineer
Check the regs
Choose as many of the finishes you can in advance
Comply with Building Control requirements
Comply with health and safety requirements
Check the insurance
Get the neighbours involved before work begins
Get the building work signed off by a Chartered Engineer who is fully insured with Professional Indemnity Insurance
A garage can be simply converted as a room but, if poorly designed, it will always feel like a garage conversion, underused and unsuitable for your needs. To avoid this, the following are a number of issues to consider in order to make the most of your garage conversion:
For added comfort and space, think of lifting the roof level to provide a minimum ceiling height of 2.4m (8ft])
Install new windows or rooflights to provide adequate natural light and ventilation.
Upgrading the insulation to current building regulation standards.
Running the flooring across the room draws your eye across, making it feel wider.
Large glass windows to the front can make it brighter and feel larger.
