zuidas amsterdam






competition, 1st place


residential, mixed


In 2021 we designed the ‘Petteflet’ after the famous book ‘Puk van de Petteflet’ by the celebrated Dutch writer Annie M.G. Schmidt. The design and concept were created during a tender for a housing building designed with young families in mind on the Zuidas in Amsterdam. Playfulness prevails in this concept, looking at the character of younger generations, stimulating adventure, wandering, and learning through play and creation. The plan follows a parkour of broad corridors with each its pedagogical theme, that flow throughout the building.

From the corridors, there is access to several common green setbacks in the facades. These setbacks are connected to each other as well as to the roof by stairs in the facades. These green spaces and stairs enhance the sense of exploration for children, allowing them to move freely from inside to outside. Small messages are hidden in the building with a nod to Annie M.G. Schmidt’s story, introducing children of all nationalities to this imaginative Dutch children’s universe.

The corridors throughout the Petteflet are the building’s main arteries and are a vital part of the building’s liveliness by connecting the plinth and the rooftop garden, both collective spaces with various functions and room for all sorts of activities. The plinth contains three spaces, optimally connected by maximum transparency and permeability. On the west side sits a restaurant with a changing international cuisine every month. This changing cuisine reflects the diversity of the neighbourhood. Residents/families from the Petteflet and people working in the Zuidas come here to meet, gather and enjoy an easy and accessible way to have dinner in a familiar setting.

Petteflet contains various housing types, with maisonettes and single-story houses ranging from two-to-five bedroom homes. The maisonette typology is particularly suitable for families, as those houses are clearly divided, allowing children to go to bed while parents can still receive visitors in the living room. The relatively wide houses make it possible to create many pleasant rooms with abundant daylight.

As much as 20% of De Petteflet comprises communal spaces in, on, and around the building’s facades. These spaces are an extension of the dwellings themselves and offer children and residents plenty of freedom of movement within the Petteflet.

The spacious balconies offer each starter/ (young) family its own outdoor space with integrated greenery. The deep niches in the façade and the sharp connections through the detailing of the metal sheets, all at different angles, create a light, rich and varied image reflected against the sky. On top, the building is terminated by its transparent crown.
