Since there is always something to do, here is my latest project.
The requirement was for a modern look while keeping costs low.
Total cost approximately 1700 euros.
Wood 350 euros, currently one third of the price at the timber mill compared to the hardware store.
HPL 700 euros, price per square meter 49.90 including cutting to my specified dimensions.
Acrylic glass, 10 pieces, 100x30x6mm (3.9x1.2x0.24 inches) in gray, 200 euros.
Screws about 80 euros, bought cheap on eBay, easily 50% less expensive than at the local hardware store.
20 Tox screws for Poroton bricks, 14 euros.
100 wood screws 6x120mm (6x4.7 inches).
100 wood screws 6x90mm (6x3.5 inches).
500 wood screws 5x50mm (5x2 inches), all used up...
100 lacquered stainless steel screws, 17 euros. Need to reorder those.
50 sheet metal screws with sealing for the coping.
EPDM foil with adhesive, 230 euros.
10 OSB boards for 60 euros.
3 sleeves for embedding in concrete, 10 euros.
2 bags of ready-mix concrete, 10 euros.
I have planned this for a while but kept hesitating because I wasn’t quite sure how to carry it out. I have always seen the finished garden sheds from the outside but never the actual build process.
So here is my contribution to help others overcome their hesitation.
A positive side effect is that it hides the plant containers :p
Work will continue next week; for now, the kids come first on the weekend.

Hello everyone 🙂
I’m currently working on the same project. I had a local timber construction company assemble the garden shed according to my plans and set it on concrete block foundations. Basically, like a kit.
I placed the foundations 10cm (4 inches) above the finished floor level to keep the structural timber (KVH) away from moisture.
I want to build the roof overhang as a boxed soffit to install recessed spotlights. This means there will be several HPL panels where precise measurements are crucial, especially for the joints.
@Offtopic where did you get your panels from and what is the name of the “color”? It looks really good on your build. Your basic concept is similar to mine, except I have two walls made from gabions.
Looking forward to seeing how it progresses. I’m also curious about the plexiglass inserts – they’re on my list too.
Best regards, Bodo
The frame is up so far:

How large are the panels on your side? I don’t see any cross bracing yet.
The panels are from Hornbach, color is RAL 7016. Item 10390383
However, Hornbach recently advises against using them outdoors, as the panels tend to warp when exposed to sunlight.
The cut was clean and very straight, though.
By the way, Bauhaus also offers them.
If you need to cut the panels yourself, they can be easily cut with a table saw. I got a fine-toothed blade specifically for this, so the edges hardly chip.
Work will continue in the middle of next week; I’m currently still in Turkey.

I will first staple a black underlay (similar to a breathable membrane). Then I’ll screw on a substructure, which the panels will be attached to. I’m still undecided about the material for the substructure. Wooden battens? Plastic?
The panels from Hornbach are unbeatable in price. But suddenly they’re not suitable for exterior use? That’s annoying -,-
When I look at others like Trespa and so on… their prices are quite high. Phuuu 🤨
Maybe someone has ideas for the substructure and experience with buying HPL panels?

@i_b_n_a_n wants to approach it similarly to the UK method with an underlay membrane. Do you already have specific ideas about the material for the underlay?
I have about 200 leftover pieces of HPL here, which come from the interior finishing of Mercedes motorhomes.
I wanted to cut them down myself, and since they were curved, I could have made "rounded corners" 😉
However, I left them outside for a year, stacked on a pallet. They were supposed to be weather-resistant.
Now I probably have to discard all of them because they blistered after the frost last winter 😡
Very, very frustrating. Money, time, and then disposal on top of that. I’ll have to choose a different material now; it won’t be Trespa.
For the UK, I still have about 2-3 cubic meters (70-106 cubic feet) of 8x4 lumber leftover from the house...
Everything else attractive for outdoor use is still extremely expensive (Siberian larch or similar).
@BodoBagger
Your little house is awesome, but probably priced toward the higher end, right?
Would you be willing to share something about the budget?
