Large glass surfaces and structure in bimetal materials. This big Italian complex developed for the headquarters of the Treviso province, was both a functional renovation and a creation of new spaces. Brombal provided the entire fenestration structure. The large curtain wall is the main part that features the building. The structure bridges corners and large glass units. Everything was made with bimetal materials demonstrating the different benefits offered by each. The outside was of burnished brass because of the high weather resistance. The inside is powder coated galvanized steel in 3 different colors.
