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.

And how will this washbasin (about 49cm (19 inches) wide?) be covered? Maybe a picture of the washbasin?

The partition wall in the washbasin area doesn’t need to be that high (how high is it planned to be at the toilet?).

By the way, the drawing shows a partition wall depth of approximately 20cm (8 inches):

Do you really need that 10cm (4 inches) of space? I’m not a fan of corners and recessed areas because, in my experience, they always collect dirt. I can’t imagine it looks nice or is convenient when mopping the floor to have to clean the corner that forms between the toilet and the washbasin separately—which really only works well if you kneel down and do it by hand. Otherwise, that corner often remains uncleaned.

So, for the sake of whoever does the cleaning and to prevent dirt from settling in such niches, I would recommend a continuous 20cm (8 inches) flush wall.

By the way, we have extra slim cisterns, and our flush walls aren’t 20cm (8 inches) deep. I can measure them at home if you want, but I’d estimate they’re about 10–12cm (4–5 inches) deep. So that could be an option as well, right?

I also really don’t like this basic offset at all.

Either we go with a continuous 20cm (8 inches) wall cladding or the 10cm (4 inches) one. However, with the narrow version, as is probably the case for you, a different wall installation system is needed, including an actuator button mounted at the top. This setup costs over 600 € net in additional charges. I find that quite expensive.

I think that’s quite a steep price.

Look at it this way: 1.9m x 0.1m = 0.19 m² (2.0 sq ft) of additional official living space. At, say, €2200 per m², that amounts to about €440, plus a wider passage and a more attractive appearance.

No, our flush plate is on the front. It could also have been installed from the top, but in this case, it is on the front. Geberit Sigma 60

Is it possible to do without the pre-wall installation for the washbasin entirely?
The pipes should also be able to be installed inside the wall.
20cm (8 inches) seems quite large for a cistern, in my opinion. I’m pretty sure ours are slimmer.
