I live in Thailand but I am Swiss citizen.
I have a plot on which I would like to build a simple garage building.
Floor plan of the building 10 x 8 meters.
On the entrance side window front with sliding door.
No windows on the back.
Narrow windows above 180 cm on both sides.
The roof should be a sloping roof.
Input side height 330cm; Back height 260 cm
Simple building block construction with metal pillar center support
( The roof has to be like the one on the picture)
