ᐅ Building an End-Terrace House as a Self-Managed Project with a General Contractor

Hello everyone,

some of you might have already followed one of my threads about us having to or being allowed to build our end-terrace house on our own responsibility – depending on how you look at it. This means that we are buying an end-terrace plot (215 sqm (2315 sq ft)) in a new development area in the Rhein-Neckar district and will be building on it ourselves – but in coordination with our two terrace neighbors.

The municipality, which sold the plots through a local resident model, ideally wanted applicants to apply as a complete housing group with several families and then build accordingly with a general contractor, construction manager, or architect. Of course, that didn’t really work out, so now there are only individual applicants and also homeowners.

After we were awarded the plot, the addresses of the other terrace neighbors were shared to discuss certain matters, such as roof style, whether or not to have a basement, etc. It was immediately clear that everyone preferred to do their own thing. However, we were still able to agree that the housing group will have a gable roof with a pitch of 35 to 40 degrees (within this 5-degree range).

As the end house, we will build without a basement, while the middle house and the other end house will have basements. This obviously presents a challenge as we would have to make a deep foundation or simply skip it, and the middle house would have to support us, as we will start construction first. The current agreement with the middle house is that we will build a deeper foundation at his expense, as supporting our house later on would be considerably more expensive for him.

We are currently close to signing with the construction manager, the notarization appointment for the plot is at the end of June, and we hope to start construction in the fall of this year. Meanwhile, several other freely planned housing groups are being built around us, which might get in the way with their cranes.

I will document the progress here from time to time – such a self-planned terraced house doesn’t come along very often.

I would team up with the others

This can't be true!

That would be pretty crazy. You just need to remove the topsoil (which has to go anyway) and then you’re at basement level. The basement should only cost about half now. I would get some quotes, even without involving my general contractor.

I already obtained quotes for the basement before signing the contract – besides, you still have to consider follow-up costs in the basement such as screed, floor coverings, water/sewage, electrical work, and so on. We will calculate everything once the exact heights are determined. The base price for the basement excluding excavation is 44k with our general contractor – estimated costs for foundation and materials are about 20k.

What I wonder here is why the municipality is not required to inform a buyer about the significantly higher road level before the sale? There was never any mention of such differences. I have now learned from the construction manager that there is apparently a height difference of about 1.50m (5 feet) at our plot. Can the municipality not be held responsible for this?

Is there no way to hold the municipality responsible?


There are plans that your general contractor should review.

Before purchase, no plans with elevation details were provided to us.
