Building a basic ground-level deck is achievable for anyone comfortable with a drill and a saw. It takes a weekend for a 3m x 4m deck and saves £1,000-2,000 in labour.

Step 1: Planning

Check if you need planning permission — most ground-level decks under 30cm high are permitted development. Mark out your area with string lines. Remove turf and lay landscape fabric.

Step 2: Foundations

Concrete deck blocks at 400mm centres along each joist run. Level them carefully — this is the most important step.

Step 3: Frame Construction

Build the subframe from 47mm x 100mm treated timber joists at 400mm centres. Check diagonals for square.

Step 4: Laying Boards

Start from the house wall. Leave 5-8mm gaps between boards. Pre-drill screw holes. Use stainless steel screws.
