Headquarter Goede Doelen Loterijen

New office for Dutch charity lotteries: energy neutral under aluminum leaves The Dutch organization Goede Doelen Loterijen (Charity Lotteries), with their three different lotteries the biggest group of charity lotteries in The Netherlands, has about 500 employees that have been working at various locations for years. Benthem Crouwel Architects designs the expansion and renovation of their new office, where they can all efficiently work together: a sustainable, open and accessible building that expresses the values this organization stands for. Employees were invited to actively participate in designing their new office. The new building will house a public restaurant, a TV studio and an auditorium that can be used for exhibitions and lectures. An open building, not just for the staff, but also for the beneficiaries and the people from the neighbourhood. The remarkable roof was designed after workshops and meetings with employees. Both the greenery at the old locations and the trees in the park that is close to the new location, are represented in the roof and its construction. The roof is carried by six columns that are shaped like trees, and itself consists of 6.800 leaves of polished aluminum that create a beautiful and organic pattern of light and shadow. By constructing the roof over the entire, existing building, the current patio becomes a large and open courtyard. By choosing to renovate and expand an existing building instead of designing a new one, and by using the newest sustainability techniques, the new housing for the Charity Lotteries will be an almost completely energy neutral building and earns the BREEAM rating ‘Outstanding’.
