Removing asbestos sheets and build walls

[Nitell]

Hello

I have a garage which is 100mm from the neighbouring fence. It has asbestos roof and side panels. I plan to remove all the sheets. On the side with the 100mm gap I will build a 250mm (10inch) wall on the garage forndation. On the opposite side extend by same amount by constructing the wall on a 500mm (20inch) foundation.

The side opposite the door has a 100mm thick concrete wall. Do a foundation there and put up another 100mm wall (now 250mm).

Can some please advise if that will be faesible. See sketches.

Thanks for your advice.

What are the criteria of feasibility?

What's wrong with 100mm walls and an occasional pillar?

Thanks for your replies.

I have never done that type of addition, such as the 100mm, before, so I wanted to see if anyone could spot any error.
