EdStarkHello everyone,
I want to have a single-family house built "turnkey" by a construction company and would like to save money on the garage (costs about 35,000 EUR for a double garage, solid construction).
The garage will be attached to the house, so there will be no gap between the garage and the house. I plan to have the foundation made larger by the general contractor to cover both the house and the garage. I think this will save the need for the concrete mixer truck to come back a second time. The building permit or planning permission should also include the garage. The dimensions are 6.4 m x 9 m (21 ft x 30 ft) including a workshop area, with boundary development.
Is it possible to build the house completely finished with exterior plaster and, after final inspection, then add the garage (build up 3 or 4 walls?, flat roof on top)? I also want to have high-voltage wiring prepared to the garage and later have the electrician do the final wiring inside the garage.
I am interested in your experience with general contractors. How did you handle this technically and in terms of scheduling?

The contract doesn’t mention anything about it, and I am only paying for the foundation slab.

Dimensions are 6.4m x 9m (including workshop) with adjacent boundary construction. Then it’s probably about 40cm (16 inches) too wide, I would say.

Who is responsible for obtaining the building permit / planning permission?
Who prepares the construction documents?
Who provides the structural engineering calculations (statics)?
Someone has to do it, and they usually expect payment for their work.
Do you want to build according to §62 or §63 of the Lower Saxony Building Code?
Workshop and boundary development exclude each other because the garage loses its privilege regarding the setback from the property line according to §5, paragraph 8, sentence 2, 1st Lower Saxony Building Code. In that case, you need a formal easement from the neighbor.
You want to apply for and get approval for the garage but not include it in the final inspection? I don’t think your mix of partial services from the general contractor and self-performed work will work that way. Neither the general contractor nor the authorities will agree to that.
