ᐅ Overlapping Utility Lines on Property – Any Experiences?

Hello,

I plan to start building my single-family house next year and will soon apply for the natural gas connection.
The situation is that I am planning a double carport next to my utility room, where the gas pipes exit. According to the utility company, it is not recommended to build over utility lines (not only gas but other lines as well).

What are your experiences with this issue? I just found out about it, and my architect did not mention anything. The pipes can only exit the house where the carport is planned. I am now considering arranging two parking spaces one behind the other instead of side by side to keep the lines clear. Would that make sense? In case of a malfunction, I would have to pay for breaking up and repairing the interlocking pavement.

I have attached a sketch showing the pipe route and the carport location.

Thanks in advance for your help!

Building over utility connection lines is indeed generally discouraged; however, in the case of a simple carport that is open on at least two sides, in my opinion it should not be prohibited as long as
a) you cover any additional costs resulting from access difficulties in case of a fault due to the overbuild, and
b) deep pad or strip foundations are not placed directly on the lines or within their protective zones.

If necessary, additional protective measures may also need to be implemented.

This also concerns more lines. I would seriously consider that. With the way technology is changing, you constantly have to expect that new cables or wiring will be needed. What about the water connections?

I would also find two cars parked one behind the other inconvenient. Is it possible to place the utility room on the north side of the house?

I also wouldn’t like having 2 cars parked one behind the other. Can’t the technical room (HAR) be located on the north side of the house?

All the utility lines, including the water connections, exit on the side. Unfortunately, I haven’t come up with a better solution yet, except maybe moving the parking space closer to the street in front of the house (although a carport might not be possible there due to the building setback line) and then building only a single carport at the property boundary. Unfortunately, there is also a street lamp and a sewer access shaft at the front by the road.

I can’t move the technical room (HAR) anymore, since the building permit (planning permission) has already been approved.

I believe the building authority is only concerned with the external dimensions and elevations. As far as I know, they don't pay much attention to the interior. However, they are stricter about any pipes or installations being encroached upon.

I don’t really want to make any more changes to the interior layout; I would rather find a different solution (such as changing the parking spaces).

And isn’t it often the case that in many houses the utility room (HAR, house utility room) is adjacent to the garage or similar, resulting in encroachment on utility lines unless the utility room borders two exterior walls?
