AC Marriott Sant Cugat, Luxury hotel

The AC Marriott Sant Cugat is a 4-star hotel in Barcelona, in the commercial area of Sant Joan. The hotel has 152 rooms, several meeting and event rooms and all the usual services and facilities offered by AC Hotels by Marriott. The chain has decided to renovate to enhance the façade, with the aim of giving it renewed elegance.

The part of competence GammaStone is the framed cladding of the windows, as well as the building's entire façade in the same material. The C-shaped panels, with two prefabricated monolithic corners, demonstrate the extreme flexibility of glass use and streamline the installation process to remarkable levels. The glass chosen in the reflective colour gives particular brightness and elegance to the building as a whole. The result is a continuous reference to modernity and minimalism as a concept, before even as a style. In particular, it indicates the tendency to make the most of sunlight thanks to the large windows finished with our product.
