Raised beds solve a handful of problems at once: better drainage, warmer soil earlier in the season, and a lot less bending over. This is the version we'd actually recommend to a first-timer — no complicated joinery, no specialist tools.
What you'll need
Tools
- Drill/driver
- Saw (hand saw or circular saw)
- Tape measure
- Spirit level
Materials
- Untreated timber boards (we used 2×8 pine)
- Exterior-grade screws
- Cardboard or landscape fabric for the base
- Topsoil and compost, roughly 2:1
Quick tip
Keep the bed no wider than 4 feet if you'll be reaching it from both sides — any wider and the middle gets hard to weed.
Step 1 — Plan the size and site
Pick a level spot that gets at least six hours of sun. We went with a 4×6 foot bed at 11 inches tall — tall enough for root vegetables, short enough to build in an afternoon.
Step 2 — Cut the timber to length
Cut two boards to 6 feet and two to 4 feet per layer. Double-check every measurement before cutting — this is where most first attempts go wrong.
Common mistake
We cut both short sides from a single board without re-measuring the second cut, and ended up two inches short. Measure each cut individually, even when it feels repetitive.
Step 3 — Assemble the frame
Screw the corners together with two screws per joint, checking the frame is square by comparing both diagonals — they should match within about half an inch.
Step 4 — Position and fill the bed
Level the frame on site, line the base with cardboard to suppress weeds, and fill with a soil-and-compost mix. Water it in before planting.
Result
Total build time was just under three hours, most of it spent double-checking measurements. Two seasons in, the joints have held up fine with no signs of rot.

FAQ
Do I need to line the bottom of a raised bed?
Not always — but a layer of cardboard suppresses grass and weeds underneath and breaks down naturally over the first season.
What wood should I avoid?
Skip pressure-treated lumber if you're growing edibles, since older treatments can leach chemicals into the soil. Untreated cedar or pine both work well.
How long will an untreated timber bed last?
Typically 5–8 years before the boards need replacing, depending on climate and how wet the site stays.
