Build questions, answered

The things people keep asking on DIY and trade forums. Short answers, what to check, and a tool opened on that build so you can try it with your own sizes.

  • How do you frame an L-shaped deck?

    Where the joists stop at the inside corner, they need a beam under them. Most mistakes start there.

  • How much extra decking should I order?

    Count real board lengths, not square metres. Then add a small allowance for cuts.

  • What is the best base for a garden room?

    Ground screws, concrete pads, a slab or existing paving. It depends on your ground, not on fashion.

  • What goes inside a garden room wall?

    From outside in: cladding, battens, breather membrane, sheathing, the frame, insulation, vapour layer and lining.

  • How deep should fence posts go, and how far apart?

    About a quarter of the post in the ground in the UK, deeper where there's frost. Spacing follows the panel or rail length.
