I have a garage conversion measuring 5m x 2.5m x 2.3m high. It has two doors (one internal, one external) and two small windows. The walls are plasterboarded and need a skim to prepare for decorating. There are about 8 additional corners to take account of three pillars on brick deep, these have not yet been angle beaded. The windows will also need beading. I also need to skim the ceiling which is otherwise in good condition.
