Building an end terraced house - Which technical requirements should be considered?

I would find it quite acceptable to politely point out that you have developed this and that schedule for your house and also the financing. If he manages to finish the basement before you or if that still reasonably fits into your schedule, you will of course be happy to arrange it for him cost-effectively – that is, to start only after him. But you can hardly keep your company waiting indefinitely or burden yourself with higher interest costs "just" because his company, for example, has longer lead times or there were delays in the planning.

If you ever have a complete drawing, then show it here. That of course also helps to improve your design, if there is one

Will I even get a complete drawing of the entire beam?

The thread is getting more interesting by the day.

Is that really so extraordinary to you? Here in the community, several such beams are standing in the latest new development area.

Is that really so unusual for you? Here in the community, there are several such blocks in the latest new development area.

In our socialist state of norms, there was no individualism. Sometimes that can also be a blessing, as one realizes now.

If the houses are staggered in depth, you could also cheekily turn your roof. Something like MadameP, if that is allowed:

Do I even get a complete drawing of the whole beam?

You’ll probably have to get or make that yourself.
At the latest, when you have yours discussed, you’ll do a hand drawing for us.

Can't you avoid the 3m offset? The goal would be: Exterior walls: high thermal insulation & thick, interior walls: rather thin and high sound insulation. Because of the offset of the houses, this no longer fits nicely. Not to mention the roof and eaves, sealing, etc. Part of the gable to the neighbor is then exposed and must be plastered or clad with slate. If possible, I would adjust the house to the middle house in your position. That was actually what this discussion was about for 20 pages.

Due to the offset of the houses, this no longer fits so nicely. Not to mention the roof and roof overhangs, waterproofing, etc. Part of the gable facing the neighbor is then exposed and must be plastered or covered with slate. If possible, I would adjust the house to the middle house. That's what has been discussed here for 20 pages.

Unfortunately, that doesn't work, and I'll tell you why: Our plot is approx. 10 x 21 and 6.5 x 21m at the neighbor's. We have to designate two parking spaces, which is no problem as a corner house, since our house width will be 7m. Thus, we can place our parking spaces next to the house.

The middle house must maintain at least 5m in front of the house for the parking space, then comes approx. 11m house and then there's 5m left to the property boundary. So the remaining space for terrace and garden is quite tight.

In our case, we can start the house directly after 2.5m, then comes approx. 10-10.5m house, then approx. 3-3.5m terrace followed by 5m garden with a width of 10m. And we find this good because we have a small garden for the kids plus a sufficient terrace.

If we were to move backward, it would be a complete waste of space since the gained free space in front cannot be used. And we also don't like having the garden on the side because then we cannot keep an eye on the kids from the terrace.

And neighbors adjusting their house to ours doesn't work simply because of the parking spaces.
