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 detached carport at the bungalow,
yes, it has vertical posts,
yes, you get out between the posts,
having posts in front of the window is inconvenient.
When it comes to the risk of cracks in the walls, that is up to your judgment and planning.

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

We only have 5.8m (19 feet) left to the property line and need to park two cars side by side there. I feel that won’t be very comfortable or spacious for getting in and out. That’s why I’m considering skipping the beams at the house wall to gain a bit more room.

You still have the posts on the other side plus possibly the roof overhang. With posts on the opposite side, you end up with about 5 meters (16 feet) of internal width. Better than a parking garage, but not luxurious.

Yes, that's true. I just realized that myself... It’s a tight space.
Of course, it also depends on how many posts I will actually need (6-8m (20-26 feet) depth for the carport). If there are only 3 or 4 evenly spaced along one side over the entire depth, it might not be such a big issue because the doors could mostly open between the posts. But if there are more (I’m still completely unsure about this), it will become problematic.
