Important to know: this is not a ready-made building kit, but a made-to-measure timber package. You give us your dimensions, we supply the timber and cut it to size where possible. The building is done by you or your contractor.
Douglas fir shed with canopy: an example
A popular layout is a 6 × 3 m rectangle. One half is an enclosed 3 × 3 m store with a door. The other half is an open 3 × 3 m canopy for bicycles, firewood or a seating area. Both halves sit under the same roof.
Below is an indicative materials list for this example. It is not a cutting list. The quantities depend on your height, roof pitch and overhang. Have the list recalculated via a quote.

Foundation on concrete post bases
Douglas fir is durability class 3. It is fine above ground, but does not belong in wet soil. So set the uprights on concrete post bases. Dig down to a firm, frost-free layer; in the Netherlands 60 to 80 cm is often used. Pour mortar, set the base level and let it cure before you load the post. Which base fits which post is shown on concrete post bases and post holders.
The store often gets a floor. That can be a concrete floor or paving slabs, separate from the bases. Keep the cladding a few centimetres above the floor and the ground, so it stays dry.
Which roof do you choose?
The roof runs on over the store and the canopy. Choose a slight fall to the back, so the water runs off one way.
- Corrugated sheets: affordable and quick to lay. A black corrugated sheet of 1.10 × 2.44 m costs €48.15. A clear PVC corrugated sheet lets light through above the canopy.
- Tile-effect roof sheets: steel sheets with the look of roof tiles, such as the tile profile sheet of 1.10 × 2.60 m for €45.25.
- EPDM: for a flat roof on Douglas fir roof boarding. EPDM 3.66 m wide costs €54.90 per metre.

Canopy attached to an existing shed
If you already have a shed, you can add a canopy to it. First check whether the existing wall and roof are strong enough. It is often safer to put the canopy on its own posts. You then only connect to the shed, without the weight resting on the old wall.
Pay attention to the roof connection. The new roof goes under the roof edge of the shed or continues at the same pitch. Make sure water does not stand between the two roofs. If you would rather build against the house, read canopy attached to the house.
Door for the store
The store gets an ordinary exterior door in a door frame. We have Douglas fir doors, single and double, solid or glazed. A single 6-pane Douglas fir door costs €535.10, a double solid Douglas fir door €1,009.75. All doors are under doors for canopies and sheds.
Building without a permit?
A shed with canopy in the back garden often needs no permit, but not always. It depends on the position on your plot, the height, the floor area and the zoning plan. So always check your plan in the Omgevingsloket (the Dutch online planning portal) before you order. We give no legal guarantee on this.
Frequently asked questions
What does a shed with canopy cost?
In our example of a 3 × 3 m store with a 3 × 3 m canopy in Douglas fir, with corrugated sheets and a solid Douglas fir door, the materials cost an indicative €2,622.85 (prices as of 13 October 2026, incl. VAT). Foundation, fixings, gutter and labour come on top.
Is a shed with canopy from Jan Sok ready-made?
Not at Jan Sok. It is not a ready-made building kit, but a made-to-measure timber package: posts, beams, cladding and roof sheets to your own dimensions.
Can I build a shed with canopy without a permit?
That depends on the position, the dimensions and the zoning plan. Check your situation in the Omgevingsloket before you order. We cannot give any guarantee on this.
Can I build a canopy onto an existing shed?
Yes, if the existing shed is strong enough. It is often safer to put the canopy on its own posts and only connect it to the shed, so the weight does not rest on the old wall.
What foundation does a shed with canopy need?
Set Douglas fir posts on concrete post bases, so the timber does not stand in wet soil. Dig down to a firm, frost-free layer, in the Netherlands often 60 to 80 cm deep.
Which roof suits a shed with canopy?
Corrugated sheets are affordable and quick to lay. Tile-effect roof sheets give the look of roof tiles. EPDM suits a flat roof on a solid deck of roof boarding.
