Douglas Fir Raised Bed Kit from the Massif Central - 3 Sizes Available
This raised bed kit is made from Massif Central Douglas fir, sourced from sustainably managed forests. It is available in three sizes: 60x60 cm (small), 120x60 cm (medium) and 120x120 cm (large), all at a height of 45 cm. The stainless steel fixings supplied ensure a durable outdoor assembly with no risk of rust runs on the wood. Douglas fir is naturally resistant to fungi and insects at use class 3, with no mandatory chemical treatment.
This raised bed is equally suited to a garden, terrace or balcony. The 45 cm high frame creates a generous growing volume placed directly on the ground. The three sizes allow the growing area to be adapted to the available space and production requirements.

Installation advice
Assemble the panels on a flat surface. Position the 4 sides and screw the corners with the stainless steel fixings supplied, starting with the lower corners to ensure the frame is plumb. Place the raised bed on a stable, clear surface — on gravel or a slab, slide a geotextile membrane underneath before filling to retain the soil. Fill with a mixture of topsoil and compost (60/40). The filling capacity is 162 litres for the 120x60 and 324 litres for the 120x120.
Maintenance and protection
Natural Douglas fir turns grey outdoors within 6 to 12 months without affecting its mechanical properties. To preserve the characteristic pinkish-brown colour, apply an exterior wood oil or stain once a year (April–May). The stainless steel fixings require no maintenance. At the end of the season, partially empty the raised bed if you live in an area with severe frost to limit stress on the joints.
WoodUp tip
Good to know before buying: all 3 sizes share the same board thickness (2.8 cm) and the same height (45 cm) — only the ground dimensions differ. Massif Central Douglas fir, rated natural durability class 3, can remain untreated outdoors; an exterior oil limits greying and preserves the initial aesthetic appearance. The stainless steel fixings supplied resist prolonged moisture from compost better than standard fixings.
Frequently asked questions
Can this raised bed be placed directly on a concrete slab?
Yes. On a concrete slab, place plastic shims or adjustable pads under the corners to ensure ventilation of the base of the wood and prevent the accumulation of standing water under the structure.
Does Douglas fir resist outdoors without treatment?
Douglas fir has a natural durability class 3, allowing it to resist for several years without treatment outdoors and not in contact with the ground. An annual oiling significantly extends the lifespan and preserves the colour.
Can several modules be combined to create an L-shaped raised bed?
Yes. The 120x60 and 120x120 modules can be placed side by side or at an angle to create L-shaped or U-shaped configurations depending on the available space. The modules are independent — no fixings between them are required.
How much soil depth can be used in these raised beds?
The usable interior depth is 45 cm, which is suitable for the majority of common vegetables. For deep-rooted vegetables (long carrots, parsnips), opt for the large 120x120 model which offers the most surface area.
Do drainage holes need to be drilled in the base?
This raised bed is open at the bottom — there is no base. Water drains naturally into the ground. On an impermeable slab, place a 5 cm layer of gravel at the bottom before the soil to ensure drainage.
