Both buildings designed by Souto Moura, have a common basis of two underground floors with 68x82,5sqm for car park. The high building, square in plan with 27m sides, has eighteen floors above the platform and the second building of three floors is rectangular in plan with 54m by 23.4m.
The massive slabs of the platform have salient capitals and on the high floors are fungiforms with 0,325m recoverable casts in the tower and 0.425m in the lower building. Initially there were planned metal capitals in the massive slabs, but for economic reasons, the solution was changed.
The dimension and modulation of the tower columns are conditioned by the facade architecture with constant geometry, rectangular with 0.30x0.50sqm in mixed section when necessary. The slabs are supported in the central nucleus and on the peripheral columns. A feature of the project focused on the compatibility of the façade with the structure, which limited the connection of the floor slabs of the columns to half of the section.
The foundations are indirect due to the low carrying capacity of the ground, with 500mm diameter piles and 800mm in the tower with 10m to 12m length.
