Elevations

The project continued with the drawings of the elevations of the house. 
The elevations let us differentiate the parts that wee see on the facade.

Here we have the North-West elevation. We could say that this is the main facade of the house, the front part. We can distinguish the facade (hatched in yellow lines), the windows (green layer) and the ground line (purple). The hole that we have on the right is the carport that lays under the second floor.

If we do a 180º rotation of the house we have the South-West elevation or the back of the house. The openings here are on the top of the facade because they will let the sun go through them and heat the house. We can see also that the carport now is on the left.

The two elevations of the sides (South-East on the left and North-East on the right) are very similar because the house maintains an axis of symmetry.
Even though, on the left we can see big openings facing the garden and on the right wee see some small windows at the bottom touching the ground line.
