manage your own project
Enough time on your hands to appoint the individual trades and direct and co-ordinate their work? You could make a substantial saving that can thus be concentrated elsewhere by stepping into the shoes of a building contractor. You shouldn’t take this on lightly, however. You’ll need to have some building know-how as well as enough hours to spare, and you’ll have to take on tasks such as supplying materials, liaising with the architect and building control, and hiring skips.
