For each building, two central cores are raised in concrete, including the staircases, the elevators and the collective accesses. The remaining areas – the apartments – are fully composed of volumetric modular steel units. While the cores are being raised on site, the steel modules are under production in the factory simultaneously. In this case, the project is more like a script, where every step is anticipated to accelerate the building process. First, the preparation of the foundations and the central cores takes place. Then, the steel modules, completed offsite, are transported and placed. A zinc coping is applied along the entire perimeter of each floor, protecting the horizontal joint between the modules from the rain. Each two modules are connected through a threaded rod with a 20 mm diameter, ensuring the stabilisation of the assembly. Once the procedure is complete for all the modules, it is time to waterproof the roofing, complete some last connections and install technical equipment.

The result will be two building blocks, with 24 apartments each, one of them with commercial spaces on the ground floor. Each floor contains six dwellings, all of them with natural cross ventilation. Despite the rigid configuration of the buildings, flexibility was considered as a strategic driver for the layout: big entrance halls balance out the small dimensions of the dwellings, thus creating a sort of additional compartment for an undefined use, and the two central apartments might assume different typological configurations, depending on the position of the division wall. While on-site works, including foundation preparation and infrastructure development, are well underway, the prefabricated modules are being manufactured in a controlled factory environment. Once completed, the modules will be transported to the site for rapid assembly, minimising disruption.
