Raised beds are garden beds built above ground level, usually framed with wood, metal, or blocks. They improve drainage, warm up faster in spring, reduce weeds, and make gardening easier on your back and knees.
What You Need Before You Start
Materials (choose one type of frame)
- Wood (cedar, larch, or untreated pine)
- Galvanised metal panels
- Recycled plastic boards
- Concrete blocks or bricks
Tools
- Tape measure
- Saw (if cutting wood)
- Drill + screws
- Spirit level
- Spade or garden fork
- Wheelbarrow
- Staple gun (for lining)
Optional Extras
- Weed membrane
- Landscape fabric
- Cardboard (for no‑dig base)
- Corner brackets
- Mulch (woodchip or straw)
Choosing the Right Size
Best dimensions for beginners
- Width: 1.2m (4ft) — so you can reach the centre from both sides
- Length: 2.4m (8ft) is ideal, but any length works
- Height:
- 20–30cm for shallow crops
- 40–60cm for vegetables with deeper roots
- 60–80cm for mobility‑friendly gardening
Why these sizes work
- Easy access without stepping on the soil
- Good root depth
- Efficient use of materials (timber comes in 2.4m lengths)
Where to Place Your Raised Beds
Choose a spot with:
- 6–8 hours of sunlight
- Good drainage
- Level ground (or levelled with a spade)
- Easy access to water
Avoid placing beds too close to hedges or large trees — roots will invade the soil.
Step‑by‑Step: How to Build a Wooden Raised Bed
1. Cut and prepare your timber
You need:
- Two boards at 2.4m
- Two boards at 1.2m
- Thickness: 2.5–5cm
- Height: 20–30cm per board
Assemble the frame
- Lay the boards out on the ground
- Screw corners together using 2–3 exterior‑grade screws per joint
- Add corner brackets for extra strength (optional)
Position the frame
- Place the frame where you want it
- Use a spirit level to ensure it sits flat
- Adjust soil underneath if needed
Prepare the ground
Two options:
No‑dig method (recommended)
- Lay cardboard over grass
- Overlap edges by 15cm
- Add a layer of compost on top
Traditional method
- Remove turf
- Loosen soil with a fork
Line the bed (optional)
Use landscape fabric if:
- You want to reduce weeds
- You’re using softwood and want to extend lifespan
Fill with soil
Use this mix for best results:
- 40% compost
- 40% topsoil
- 20% organic matter (leaf mould, well‑rotted manure, or soil improver)
Fill to 2–3cm below the top.
Water and settle
- Water thoroughly

- Top up if needed
How to Build a Metal Raised Bed
Metal beds are quicker:
- Unpack the kit

They last 20+ years and are great for wet climates.
Building Raised Beds with Blocks or Bricks
