ᐅ Attached carport (lean-to) or a freestanding one— which is better?

Hello everyone,

We are planning a bungalow with the company Hanse Haus. The salesperson included a support beam in the exterior wall (this is needed in prefabricated houses when heavy loads are to be mounted on the house). During the more detailed planning phase with the architect, we were advised against this, with the explanation that later slight settling of the house and/or carport could cause stresses on the exterior wall, which might lead to cracks or similar damage on the facade. It would be better to build the carport completely free-standing.

In general, it is probably "better" to have the carport free-standing and structurally completely separated from the house. However, practically this is difficult. In our case, several supporting posts would be placed along the walkway by the house wall facing the garden, which is inconvenient. Also, these posts interfere when getting in and out of the car. Aesthetically, it is also less than ideal, as these posts (with some spacing) would be positioned in front of windows.

Since I often see both options in real-life examples, I wanted to ask whether it is really advisable not to attach the carport to the house wall and accept the respective disadvantages instead. Could someone share their experience from their home construction or from acquaintances?

Thanks in advance and best regards,
Martin

We have a beam attached to the wall for a (really massive) wooden carport with an extensive green roof. I believe it was calculated together with the entire structural statics of the house. After one year, I can’t see any issues at the wall. However, the carport wood certainly undergoes some expansion and contraction. At the time, I thought all the foundations were huge.

We also didn’t want any beams “in the way.” In the end, though, I think you would quickly get used to them.

We have a freestanding wooden carport, about 6x6 meters (20x20 feet), roughly. There are three vertical posts on each side: one at the front, one at the back, and one in the middle. I park in a way that I don’t hit the door on the middle post, so there’s enough space to get in and out. With a depth of 6 meters (20 feet), a middle post should work fine for you as well.

Detached 6x5m (20x16 feet) carport. One vehicle drives in forwards, the other reverses in. This way, each person exits on the inside. There is then about a meter (3 feet) of space between the vehicles, which can also be used as a passage to the garden/patio/garbage area.
