To give you an idea of the size and layout of the carport/storage, here are a few pics. We had a countertop built which was 4 meters long and contained a sink with faucet and under counter storage. This has worked well when praparing food or washing dishes.
Here is the entrance to the carport and each bay is 4 meters wide. Plenty of room for the Vigo and Yaris.
This pic shows the storage which is 8m x 8m. We tried to line up the window with each other and the door to take advantage of the breeze that is pretty constant from the back of the garage.
All in all, I am pretty happy with this space and see it being used more by the family for cooking and parties than the house. This was another reason for building a larger structure to park the cars. The family seems to like being outside and I will have some peace and quiet once the house is finished.
