The London-based architecture firm, PLP Architecture, recently won the international Delftseplein competition for its hybrid tower project known as "Tree House." The $177m (£137m/€160m) project will stand at 459 feet (140 meters) and will be constructed using mass timber and concrete materials. 

Said to be the tallest hybrid structure in Holland, the tower will house 275 apartments in addition to other offerings such as office/co-working spaces, cafes, shops, and a restaurant that will sit on the tower's seventh floor. 

The 37-story building was one of three competition finalists (along with UN Studio and Group A). According to PLP's project statement, "The building is being designed to stand at the forefront of architectural sustainability and will feature a part-timber structure with a concrete core, significant reused and recycled materials, rainwater collection and reuse and CO2 storage. External balconies and terraces feature plantings and greenery, spreading up towards a crown of three glazed greenhouses filled with trees and gardens to emphasize a commitment to biodiversity." 

The UK's Building Design received a statement from PLP Architecture's partner Ron Bakker discussing the project. "We enjoy designing buildings that push boundaries, and this is an innovative, sustainable, mixed-use tower, with a hybrid timber structure, almost on top of Rotterdam's Central Station - a new typology for future cities."

Working with the developer Provast, the new tower is expected to begin in 2021 with an estimated completion date of 2024.
