Design considerations when planning a garage conversion

    Converting a garage into a usable room, such as a bedroom or a study, is a great way to make better use of the space and add value to your house. Planning permission for a garage conversion is not usually required, subject to certain conditions, but a building control application will be necessary.

    The following is a summary of some of the things to consider when planning your garage conversion. For additional information, visit CR Design Services1.

    Floor levels – there is often a step down into a garage from the main house, although sometimes the garage and the house are at the same level. Any difference in levels is an important consideration when designing the proposed floor construction.

    Existing external walls – the existing external walls of the garage may need to be insulated. Whether the existing garage walls are single leaf brickwork, or a 300mm cavity wall, it’s usually safe to assume they’re not currently insulated and a new layer of insulation material will be required.

    Existing internal walls – if your garage conversion requires a new door or opening in the existing walls from the main house (or from an existing room), a structural support may be required.

    Existing garage ceiling – the existing ceiling over your garage may need to be insulated. If the garage has a room over it, there is no need to add insulation in the ceiling. If there is a roof directly above the garage, you may need to add insulation.

    Replacing the garage door with a window – when replacing the existing garage door with a window, it is common to keep the width of the original garage door opening as the same width for the new window.

    Only converting part of the garage – you could decide to convert the rear part of the garage, and keep the front part (including the existing garage door) as it is. This has the benefit of keeping some storage space for bikes and a lawnmower, whilst also maintaining an unchanged appearance at the front of the house (useful in conservation areas, for example). 

    Working from home – if you plan to convert your garage into a home office, it is unlikely that you will need planning permission. However, you may require planning permission if you intend to run your own business from home.

    If you are looking for a design team to help you with your garage conversion project, CR Design Services can help.
