Construction Equipment Shed Architect Fees

€14,000 shed would also be a statement.

14,000€ shed would be quite a statement.

6mx3m = 18sqm floor area. That is 775€/sqm ==> including foundation, base, walls, roof, electrical, windows/door. I don't find it too expensive. It's nothing other than a garage.

Garages are rarely built from wood, have different static requirements for the ground, and have gates. I spent about 2.5k on my ~9m² shed. Planning and construction were, of course, done by myself. But it is good material, Siberian larch.

However, a planner cannot and must not assume a self-built shed.

Come on.
I bought the material relatively expensively.
Now let the colleague charge double for it.
That leaves 9000 for the work.
At a rate of 50€ per hour, that's a solid 22.5 man-days.
In that time, I alone can build 3 of those sheds, a professional probably 5.

We don't know exactly how the communication between the designer and the TE was, but with the information provided here, I stick to my point: 1400€ is disproportionate, he should have told him that beforehand.

Speculating about the price of the shed is a funny sport. Of course, you can set up a shed building for less. But we do not know the requirements, tastes, or manufacturer. Just because the OP now complains about the 1400€ does not mean he has to save money.

You can also buy a sofa for 5000€ and complain about 300€ delivery costs. There are sofas that are significantly cheaper.
