A garage can function in many ways. It can provide security for your car or other vehicles, or it can be a dry place to repair household equipment. A garage can offer extra room for storage, or it can serve as an indoor playroom, home gym or woodwork room. Owning a garage can lower your car insurance premium and might add value to your house. There are many firms within the UK that can build you a garage according to your specifications, but perhaps you want to play a more active role in the building process. In that case, consulting with professionals is still a necessity.

Old discarded bricks can be a cheap and green source of hardcore for your foundation (if you dig it yourself). Toss the bricks into the foundation pit, and smash the bricks into smaller pieces. The broken pieces will serve as hardcore, providing a "key" to which the concrete of your foundation will bind.
Build away from trees if possible. If you must build near trees, dig deeper foundations. In the case of a deep foundation, pile foundations or raft foundations may be necessary. These must be designed by a structural engineer.
