Green House is the result of an interior intervention by architect Teresa Otto from Ottotto in this house in Porto, Portugal using green metal mesh to encase its original stone walls.

The house features carved out shapes to create a series of skylights and mezzanines.

Metal structure holds the new volumes with bedrooms and office, which hang above the large open plan living area.

On the exterior, the main facade was left intact while the back facade has been renovated using corrugated metal.
