The idea of repetition and ascension is exacerbated to the limit. The formal and material relief results from the overlapping of several layers, dynamically alternated and grouped. The simplicity of the structural grid frees the corners for living rooms and balconies. Using a gradient approach, from the smallest to the biggest apartment, the typologies are mixed, promoting dynamic and variety in the facade. The vertical and horizontal breaks in the edges of the volume create different and unlimited perspectives over Matosinhos.

Inspired by the repetition observed in the stacked containers at Porto de Leixões, the facade consists of 6 modular nodes, which allows to adapt the design to different uses. Besides the modular capacity of the facade, the design also enables green spaces to grow, lounge spaces and to allocate technical devices. The main facade in the background can be perceived through the cantilevered and counterfeit balconies. Although the facades are composed by the same elements, they are all different according to the sun exposure and views.

The creative process started from the concept design with the aid of freehand sketches, soon evolving to the digital field. This step became even more relevant in this project since the subject is a tower with a parametric facade and alternated type floors. Rhinoceros was the main tool in the concept design phase, allowing to produce the virtual simulation of the building’s external shape in a three-dimensional model. With this approach it is possible to swiftly bring the physical model into light by using the ‘CNC’ (Computer Numerical Control).

These tools improve the concept design process, once the digital and physical modelling work almost simultaneously. Unlike 3D printers, that use a high range of materials to create a shape from scratch, the CNC cuts negative shapes out of compact mass, usually rigid polyurethane foam board. This particular process requires a planning phase for the model but, on the other hand, allows to work with large dimensions, which is very useful in large-scale projects such as tall buildings or projects with important urban settings.

Combining both software and hardware modelling tools in the production of models, it is possible to optimize the architects work, saving time allocated to the project development.
