I am now using the shed for half a year. so it is time for a evaluation
The roof does not leak.
The concrete floor is still in one piece.
Doors are in one piece. I was afraid they were not sturdy enough.
I made a few improvements.
Rain could come in via the flour. The rain drips via the door on the piece of floor outside the shed. Then it can float in. This is a problem when it is raining for a long time. I mounted a sheet of wood on the bottom of the door to guide the rain away from of the concrete floor. This helps a lot but there is still a piece of floor that can get wet.
The concrete flour is 5 cm above the garden. I made a concrete slope to make it easier to get the bikes in and out.
