  • I'm after some advice.
    We have a turn of century terrace where the staircase is oriented across the width of the house. The master BR is at the front of the house. In the master BR there is a closet in the space above the stairwell. This closet is a strange triangular shape owing to the fact that the floor of the closet is the ceiling of the stairwell. get me?
    I'd like to put some shelving in the triangular bit. I have some leftover 18mm ply left over from another project. I am thinking of fixing four ply corner supports to the walls with evenly spaced drilled holes, so that the shelves can be adjustable, like kitchen cabinets or an ikea wardrobe.
    Access to the space is such that prefabrication will be difficult. Am I setting myself up for an exercise in frustration, owing to the fact that the walls won't be true or flat? Any tips for 'truing' the space before I start? I am a dab hand at wood but no good at plaster.
    Thanks.

  • Similar problem at a previous house: I resorted to battens shaped on one side to the profile of the wall using a spoke shave - doubtless there is a more modern power tool that will do the job, but shavings are much easier to clear up than dust. Said battens varied from 1/4" to 1. 1/4" thick, and allowed a ply panel to be fitted true, or at least as close enough, screwing through the ply and batten into the wall.
    The biggest problem I found was drilling into Victorian brick - carbide masonry drills were good for no more than two holes...

  • Can you use twin slot strips on the back

    You can shim them out to get them level or they will deform a little to follow a wonky wall (I have a turn of the century terrace too)

  • I would strongly favour trying to prefabricate something in that situation, unless it's absolutely impossible. If you want the shelves to be adjustable then the supports that they sit in/on have to be parallel all the way up. I would suggest building a liner (basically a big box) for the cupboard that is properly square and lifting it into the space (with temporary triangulation struts if needed to keep it square). If you can't lift it in whole, then could you build it, check that it's all square, dismantle it as much as needed, lift the sides/back into the space with shims to level and square it and then add any cross bracing to keep it in shape. If you've got a router you could also use recessed shelf support strips to maximise the width of the shelves.
