Chestnut Tower

Philadelphia, USA

Chestnut Tower, the tower in the garden

The Chestnut at University City is a 30-story multipurpose project in the heart of Philadelphia. The development consists of 405 luxury apartments with comfort spaces and a swimming pool. Its development is conceived just like a "tower in the garden", with indoor and outdoor spaces that offer an elegant environment for a pretty urban life in the heart of the university city. The high-end aesthetics flow into the large lobby space, to give the building monumentality and a sense of permanence. The façade is the first element on which the eye falls looking at the Chestnut Tower, being a building full of charm. Therefore, a product like the GammaStone Air in Carrara marble, which is very functional and durable while maintaining its high aesthetic quality, immediately became the perfect choice for this structure.
