My ideas
Outdoor extension
Garden black
Outside covered terrace
Front room
Bathroom like the tiles with grey grout
Full extension for terrace 1
Full extension… like the folding doors
This is a full extension but could be 2/3 in glass and the right third open terrace.
Whole outdoor space feel. Would it be too hot?
Big patio doors maybe for terrace 1
Glass wall for 1st floor terrace
Running water
