Hello,
I am currently in the process of gutting a former cold room (see photo).
The cold room consists of 3 walls with a pent roof. The fourth wall is a shared wall with a garage or a carport
on the opposite longitudinal side not visible in the picture.

The question now is the following:

The floor (concrete foundation) of the former cold room is about 40 cm below the level of the garden, where it is now to function as a garden shed accessible from the other side. The former entrance to the cold room on the side opposite the frontal view in the picture is to be bricked up.
I would then like to have a window on the long wall in the photo as well as a door accessible from the garden either in this wall or in the side wall on the left.

Because of the 40 cm height difference between garden level and cold room, I see several options:

a. side or front entrance with steps "down" into the room
b. filling the room with "material" to bridge the height difference to the garden in order to achieve an approximately level entrance
c. excavating the garden in front of the future garden shed by about 40 cm and creating an approximately 3x5 m recessed area/terrace in front of the garden shed to enable a level entrance

The room height is sufficient for all 3 variants. I am also aware that proper drainage must be ensured to prevent water ingress during heavy rain events.

I would prefer to avoid the 40 cm height difference, so variant a is actually out.

What do you think about this, and which practical and affordable options do you see to raise the floor level in the future garden shed by about 40 cm?

Thank you very much
