Hello everyone,
I’m new here and starting my first topic. I’ve read through some other discussions but haven’t found anything concrete regarding my current question.
My partner and I are planning to build a new house with a solid construction company this year. Contracts are signed, and soon we’ll have the planning meeting with the architect.
Right now, I’m concerned about the topic of prefab garages. I’ve already obtained several quotes (there are so many providers) and, as a layperson, I’m uncertain if I’ve considered everything and have a couple of questions.
What should I pay attention to in the quotes besides our special requests (sectional door with electric opener, extra door, and electrical package including lighting and sockets)?
I always ask for a quote for the foundation too, and I read that if the garage is attached directly to the house (like in our case), connection strips are required (I believe to seal between the house and garage?).
The house is a new build and will be plastered. Is it even possible to build the garage right next to it immediately, or does the plaster need a longer drying time first? If yes, how long approximately?
Also, we already have a few offers. One stands out because of the price (significantly cheaper), but it’s not made of concrete, and I can’t assess the quality at all. The offer states:
"Made from band-galvanized trapezoidal sheets and galvanized steel construction. The galvanized roof trapezoidal sheets have a double-sided aluminum-zinc coating, including connection and fastening materials. Partitioned walls!"
Also,
"4-sided parapet cladding
Finish: Coated"
I hope this isn’t too much, and maybe someone has some tips or an assessment for me.
Thanks in advance!

We got our garage from ADM Garages (Hansebeton).
2.85 x 7 m (9.35 x 23 ft).
Anthracite Hörmann sectional door,
Anthracite Hörmann door,
Electrical package (3 flush-mounted sockets, one light fixture, and one light switch).
The total cost was €8600.
The plaster finish looks almost the same as the plaster on our house.
I would definitely recommend a precast concrete garage! Stay away from those cheap metal ones!
The garage came with a conduit where the cable from the house could be connected.
Then I drilled an 18 mm (0.7 inch) hole and installed a high-voltage cable for possible electric vehicles.
I just need to connect the drainage. By the way, it’s already laid inside the garage along the back wall—a 75 mm (3 inch) pipe.
So it’s worth planning this into your drainage system from the start.

You have walls built and still install a prefabricated garage? They could easily build it for about the same price. That’s wishful thinking, Tomtom. A double price is more realistic.

Sebastian, make sure to add a continuous parapet all around. Otherwise, the plaster will soon have water streaks. Every plumber or roofer does this. Thanks for the tip.
Since there will be a carport between the house and the garage, the garage will have a continuous parapet.

But you get what you pay for. They’re not exactly attractive, and the pictures here prove it.
