5 holiday apartment buildings with 11 storeys height each inserted in a double storey basement for car parking and amenities.

The buildings assume the shape of a spiral that led to inclined columns and floors that rotate from ground floor up to the roof.

The inclination of the columns generates horizontal loads, induced internally and proportional to the structure’s gravity loads. These add to the remaining applied horizontal loads such as the wind. 

A central stairs and lift concrete core with thicker walls than initially expected (600mm and 800mm) was required to resist the increased lateral loads caused by the shape of the structure.
