Completely clad carport sides or leave the top 20 cm open

We have built a carport with anthracite-colored steel trapezoidal sheets with anti-condensation fleece as the roof; now it is to be enclosed and clad on 3 sides with a facade tongue-and-groove cladding, the front remains (for now) open... We are now considering whether to close the 3 sides completely up to the top or to leave the upper 20 cm open so that air can circulate (for moisture removal beneath the steel trapezoidal sheets) and to prevent heat buildup. What do you think or what makes sense? Another idea was to fill the upper 20 cm with light panels for light while maintaining weather tightness.
There is a purely hobby vehicle as well as the garbage cans, bicycles, Bobby car, etc., and in an annex that goes around the corner there will be a small workbench including all the tools; light panels should definitely be installed there, this room is also separated by a sliding door from the rest or from the outside.

Hello,

personally, if I were to start with it, I would close the walls as much as possible. If you leave 20 cm open, you will get moisture, leaves, etc. on the vehicle again.

As long as the driveway side remains open, there should still be no problem with ventilation.

But please check the applicable development plan beforehand. In many places, it is explicitly prohibited to close the sides of carports.

Regards,

Dirk

Yes ok, it is then no longer called Carport but small garage with us...

Nevertheless, observe the building permit. It may be that you need a building permit for the cladding depending on the design. A local architect can certainly provide you with information on this at short notice, including how strict your building authority is regarding such matters.
