This project is framed within a wider masterplan for the Fort V site, aiming to
strengthen the current function of public park. The ‚bioclass‘ is known to locals,
but needs a new infrastructure. It is conceived as a new reception centre for
education of nature and ecology for the region.
The design interprets the existing warehouse as a Hortus Conclusus, in which the
existing walls are considered as garden walls. The warehouse will be opened up in
certain area’s to allow vegetation to grow in a controlled way. Zones will be
installed which house rare plant species, a swamp, or a summer bar reception area.
The hall is the first place to start excursions for fauna and flora, which can
extend into the park of Fort V.
The Regional House itself reflects this educative and ecological approach through a
radically sustainable and participative architecture. Structurally arched walls,
inspired by the arch masonry of the fort, are made of compressed earth blocks from
local clays. An insulation façade and roof of hempcrete is left apparent as
finishing and makes this building CO2-negative. Only two construction techniques
make the superstructure of this building honest, minimalistic and educational.
19000 blocks were produced in a 3 week workshop, and 312 m2 of hempcrete was
installed in a 2 week workshop: together, more than 150 volunteers worked on and
learned with this project.
