Hole in a wall. City Square development by architect AllesWirdGut, located in Esch-sur-Alzette, Luxembourg
House in Travessa de Patrocinio by Luís Rebelo de Andrade + Tiago Rebelo de Andrade + Manuel Cachão Tojal I find this pretty interesting. The green-part fits into the architecture rather than an add-on.
