RUSHCLIFFE HOMEWORK can alter and repair existing stud walls and partitions or build new ones, add sockets, switches, TV points and radiators (subject to feed access).
I can make new openings into eaves storage from an existing loft conversion, adding a cupboard door and frame to match what is already there.
A stud wall can be added to split a room into two rooms with door frames and doors added. If you live in a house where the bathroom is accessed via one of the bedrooms, you can form a corridor for privacy, with lights, sockets and a radiator.
Maybe you want to make a new bathroom or ensuite, form a cupboard under the stairs or close off an open plan area to conform with regulations. I work with experienced tradesmen covering all of the roles involved in these alterations.
