How to build a log store: a simple raised, slatted frame

Build from the ground up: stable base, raised bearers, stiff frame, slatted floor and walls, then a roof that throws water clear. Size the clear internal bays before cutting the frame.

1. Draw the usable space

Start with required stacked volume. Choose depth from normal log length and height from safe reach, then solve for width. Break a long width into bays. Add posts, braces and overhang to obtain the external footprint.

Mark that footprint on the site. Check the walking route, roof runoff, boundary and any planning constraint.

2. Specify outdoor timber

Ask the supplier to confirm the treatment Use Class and intended service life in writing. Timber above ground but exposed outdoors is generally a Use Class 3 application. Components in ground contact or severe permanent wetting need a specification suited to that exposure. Keep timber off the ground wherever practical.

Seal or treat cross-cuts as the treatment supplier directs. Do not assume a decorative stain upgrades unsuitable timber.

3. Make a level, drained base

Prepare sound paving, pads or a compacted base. Support every load path. Set raised bearers so water and debris can pass beneath rather than collecting against the floor.

4. Build and brace the frame

Assemble front and rear frames square, join them with depth rails, then add diagonal bracing before loading. Use exterior fixings compatible with the timber treatment and roof material. Anchor the empty structure according to the site exposure and fixing design.

5. Fit floor and retaining slats

Space floor members so short logs remain supported. Side and rear slats should retain pieces without becoming solid panels. Leave the front open. Keep a free gap behind the finished store.

6. Add the roof

Give the roof a positive fall and overhang. Lap the weathering layer in the direction water runs. Direct runoff away from the stack, wall, path and feet. Make the covering replaceable.

7. Inspect before loading

Check square, fixings, sharp edges, wobble, roof drainage and floor support. Load the first bay gradually and watch for movement. Correct a lean before filling the rest.
