Spree Timber Haus is a pioneering eco-residential tower redefining sustainable urban living in the heart of Berlin. Rising beside the serene banks of the Spree River, this sculptural timber high-rise is a flagship for green architecture, seamlessly integrating nature, community, and design innovation. The tower's architecture is inspired by modular treehouse forms, composed of interlocking timber volumes with generous balconies, green terraces, and vertical gardens. Built primarily from cross-laminated timber (CLT), Spree Timber Haus is not only carbon-negative in construction but also acoustically warm and energy-efficient.
