ᐅ Building a Tool Shed Attached to Your Garage Yourself

Hello everyone,

We recently finished building and are currently planning our garden. We want to build a garden shed ourselves against the back and side walls of the garages. One garage is 2 m (6.6 ft) longer. The shed is planned to be 2 x 2 m (6.6 x 6.6 ft) and 2.5 m (8.2 ft) high.

The plan is to have five posts for the shed, which will be placed on post anchors. The post anchors will be set in concrete (four corners and one at the door). The rest of the ground is gravel concrete, and on top of that will be crushed stone and paving. The wooden frame will be made of structurally graded solid wood NSI spruce/fir, measuring 80 mm x 100 mm (3.1 x 3.9 inches).

The roof will have a 5% slope and will be covered with roof tiles.
We are planning a sliding door.

What do you think of our plan?
What would you recommend for cladding?

Thanks in advance

I built something similar using a timber frame. However, I think a 5° (9°F) roof pitch with an EPDM roof and roof tiles is quite low.

It is about 5 meters (16 feet) long and about 3 meters (10 feet) deep.

I anchored an 8x11 beam directly to the garage and placed the cross beams on it. I used post brackets at the corners.

I also have some pictures of the timber frame somewhere.
I clad it with HPL panels.

Where the shadow is, there is a door leading outside with folding hinges. You only notice it if you know it’s there.

It looks really neat. Why do you think the roof pitch is too low?

I’ll have to take a closer look at those hinges.

Back to the sliding door: the automotive industry manages to install sliding doors flush as well 😉 No offense, I’m just gathering ideas and this toy-like mechanism is quite simple 🙂

Because you are planning to use roof tiles. They won’t work in this case.

I have roof tiles installed on a 20° pitch. Maybe you can get used to that.

Wasn’t that this one here?

I went looking because I also remembered one with a sliding door:
