Dutch firm MVRDV has revealed plans for a 12-storey mixed-use office building to be constructed in the south german city of esslingen. named ‘the milestone’, the 6,500 square meter structure boasts a distinctive reflective façade with a void at its center. inspired by the appearance of crystallized rock, the interactive elevation is a reinterpretation of esslingen’s topography, and carries messages about the town’s history and people.
