Carport attached to the house wall (lean-to carport), or would you prefer it to be freestanding?

Hello everyone,

we are planning a bungalow with the company Hanse Haus. The seller had me include a "support beam" in the exterior wall (this is required for prefabricated houses when heavy loads are to be mounted on a house). During more detailed planning by the architect, we were advised against this again with the reasoning that slight settling of the house and/or carport later on could cause stresses on the house wall, which in turn could lead to cracks or similar damage on the facade. It would be better to set up the carport entirely free-standing.

In general, it is certainly "better" to set up the carport free-standing and completely separate structurally from the house. Practically, however, this is not feasible. So I then have several support beams in the walkway at the house wall towards the garden that are in our way. In addition, these beams then interfere when getting in and out of the car. Also, from an aesthetic point of view, it is suboptimal and these beams would (with some distance) also stand in front of windows.

Since I actually often see both variants "in the wild," I wanted to ask whether it is really advisable not to have the carport mounted to the house wall and instead accept the respective disadvantages. Can anyone perhaps share experiences from their house construction or acquaintances?

Many thanks and regards
Martin

We have a detached carport at the bungalow, yes it has vertical beams, yes you get out between the beams, beams in front of the window are annoying. When it comes to the risk of cracks in the walls, it is your discretion and planning.

How much the posts disturb also depends on the planned width. The neighbor has his carport "freestanding" right next to the house. However, as far as I know, no reinforcement was planned there.

We only have 5.8m left to the boundary and need to be able to park two cars side by side there. I would say it probably won't be very luxuriously comfortable for getting in and out. For this reason, I am considering whether I could "skip" the beams on the house wall to gain a bit more room.

You still have the posts plus possibly the roof overhang on the other side. With posts on the other side, you’re left with about 5 meters of interior width. Better than in the parking garage, but not luxurious.

Yes, that's true. I just realized that too... tight fit... It also depends on how many posts I will actually need (6-8m depth for the carport). If there are only 3 or 4 evenly spaced on one side along the entire depth, it might not be so bad because the doors could usually be opened between the posts. But if there are more (I have no idea yet), it will be problematic.
