<p> If it sounds hollow, it is probably a stud wall (plasterboard – or lathe and plaster in older properties – attached to solid wooden uprights).

Remove the shelf. <br /><br />Position your brackets so that the part the shelf rests on is level with the line <br />Check that the brackets are vertical using the spirit level, then make pencil marks through the holes.<br /><br />Remember to check the wall before you drill. Survey the wall for electrical sockets and switches, gas or water outlets, and use a cable/metal detector before drilling.<br /><br />Drill a hole the same diameter as your fixing, either through the plasterboard or, in the case of solid walls, the same length as the wall fixing.

Screw a wooden batten to the back wall slightly shorter than the recess (choose a batten about 30mm wide and 10mm deep). Then screw a batten either side to the same depth as the shelf.<br /><br />Place the shelf on top and screw to the rear batten. If you use heavy-duty fixings, this type of shelf will hold books.</p>
