As a residential tower to be realized in Barcelona, Alpha tower is designed in form as a culmination of multiple boxes around a central core. While the boxes are separate from each other in façade, they are completely fused and inseparable inside the plan. The combination of the boxes differs along the levels of the tower, in two parts: one on the ground level, where the entrance is located, and another part in the middle of the tower, where terraces and semi open living rooms are placed instead of the eliminated boxes.
The double staircase core serves as the access zone, structural core, and service area. The thick concrete walls on both directions of the core, makes the façade system free and interpretable, especially by eliminating a need for bracing beams. The segregated and jagged form of the tower in those two parts, not only provides space for terraces and outdoor living rooms, but also have a great impact on smoothing the wind blow and regulating it for the terraces to be usable.
The formal concept in Alpha tower is a technique to kind of integrate earlier models of urban apartments with more modern midtown residential towers. Whereas a central core and a freed façade adhere to modern tower models, living in terraces and enjoying open and green spaces on the exterior of a housing adheres to 3 to 4 level urban housings of earlier urban models. Alpha tower is an architectural revision of both models.
