The new Prati di Gries tower interprets a housing demand for social housing through a contemporary and sustainable light

harmoniously fitting in with the surroundings with which it communicates through numerous perimeter terraces and triple-height loggia.

The area dedicated to neighborhood services and social activities on the ground and first floors create a bridge between the square in front and the new park in the back: the totally car-free exteriors offer children, teenagers and adults many opportunities for leisurely activities.
The large colonnade on the ground floor facing south and west allows for the use of the outdoor areas even during the coldest periods, thus extending the meeting places also outside.

The choice of wood, a naturally sustainable material widely available locally, as the main constructive element of the building helps to reduce the impact of the building in its life cycle, thanks to the possibility of completely reusing it during the decommissioning phase.

The large wooden eaves of the intrados is a clear reference to the Alpine construction tradition, allowing the facades to be protected from the elements to the advantage of their durability.

The hybrid structure in reinforced concrete, steel and x-lam allow to take advantage of the potential of the materials and to ensure a good degree of prefabrication.

The planimetric distribution allows to have all the living areas correctly exposed to south-east / south-west so as to maximize passive solar gains, and favor cross ventilation thanks to the internal layout.

The complex, located in the Casaclima A Plus class, will house about 35 residential units and neighborhood services and will be built within the new district called “Prati di Gries”, dedicated to environmental sustainability.

The hybrid structure in reinforced concrete, steel and x-lam allows you to make the most of the materials’ potential in terms of structural performance, execution times and ease of maintenance. The predominance of wood allows to reduce the CO2 footprint of the building, and, together with the steel structure, guarantees an excellent degree of prefabrication and dry assembly for maximum interior flexibility.

A characteristic L shape, symmetrical and compact, allows having all the living areas correctly exposed towards the south-east / south-west in order to maximize passive solar gains and have internal layouts that favor cross ventilation.

Particular attention has been paid to the detailed design of the balconies and loggia: the balconies, with intrados in shades of green and variable density railing, are what give harmony to the facade; the triple-height loggia, with the important presence of vegetation, offer a strong identity to the tower itself, reinforcing the building’s green vocation.

The strong insulation of the envelope limits thermal asymmetries: in order to respond to low energy needs it is sufficient to integrate the ventilation system with a thermal battery, simplifying the plant structure of the building, powered by the district’s heating network.

In domestic environments, the orientation towards the finishing choices, coatings and furnishings with mainly natural components not treated and free of VOC and formaldehyde, together with the green wings and optimal ventilation, help to raise the psycho-physical well-being of the inhabitants.

The roof houses a 20 kWp photovoltaic system, covering the condominium services such as lifts, utilities of the spaces dedicated to social activities, stairs and technical rooms.
