ᐅ Single-family home turnkey construction with owner-built garage

Hello 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?

And there, is boundary-to-boundary building unlimited?

Yes, up to 9m (30 feet) in length without the neighbor’s consent. There is no mention of width or area.

In total, however, it is 15m (49 feet), and you are planning 15.4m (50.5 feet).

Of course, the garage also requires structural engineering. I think you might be a bit too optimistic about this. What exactly do you expect to save financially? €35,000 is a reasonable price.

I don’t understand. I’m not building in a corner, only the 9m (29.5 feet) side is on the boundary, right?

I have built a garage before, so it’s still undecided whether I will do it myself again or have a company build it. I think it can be done significantly cheaper than 35,000€.

Now we know that. Previously, you only spoke generally about building on the boundary.

I’d estimate around 5,000 euros. A bricklayer team can build it up in two days. The money doesn’t go there. The cost mostly comes from the materials.

Maybe around 5,000 euros. A team of masons can build the structure in about two days. The money wouldn’t be spent there. It’s more the materials that add up.

I will run the numbers again, thanks.
