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.

However, the picture is very misleading. Since the subcontractor from Netze BW has not yet closed the opening for the house connections, the screed sand could not be unloaded on our property. Otherwise, all other builders had to cover their streets with protective sheets to keep the road intact.

Therefore, the street is still in its original condition because everyone is unloading their materials somewhere on various properties. This is not a problem as long as no one else needs the space. We don’t have the kind of small disputes over “that’s my 5cm (2 inch) piece of land” like in other developments. Everyone finds the space they need – the rest is managed among the tradespeople.

That small amount of screed sand won’t harm the paving. The heavy-duty traffic will crush the paving. Since the development authority has planned that everyone may either raise their plot by about 150 cm (5 feet) or build a basement, quite a few trucks will be driving over it. You could ask the local authorities what expected service life they assume under these specific conditions.

However, in this area, it is simply common practice to finish the roads first and then start building.
I constantly see this in new housing developments. If it were such a huge mistake and every time the adjacent streets had to be completely redone immediately after the construction phase, someone probably would have thought about it by now.
If the subbase is properly compacted, the roads should be able to withstand it.

We are still missing the top layer; it will only be applied once most of the houses are built.

The asphalt base layer is usually less of an issue. The nice curb stones and concrete paving suffer more from this.

Our local civil engineer will be preparing the area around the house in the next few days by spreading and leveling the 110m3 (145 cubic yards) of soil already on site at a reasonable price.

Advantage: there are about 80 cubic meters (105 cubic yards) of compactable excavated material on the neighboring property that we can take for free. Otherwise, all the levels will be set to ensure they fit properly for the paving contractor later on.

On the neighbor's side (the other end townhouse), about 1.50m (5 feet) will need to be sloped. Whether this can remain as is if they excavate their basement will have to be determined later.
