The heritage site of Hembrug used to be the center of the production of weapons and ammunition within the Netherlands during the twentieth century. Now the site is mostly vacant and awaiting a new purpose. Most of the site used to be densely build with industrial halls, but there is one area that is different. The old explosive factory within the site of Hembrug has an unexpected relationship with its natural environment. The abundant greenery on this site is not only important for how the site is currently experienced, but it is also a crucial part of the sites heritage. Therefore it should also be an important part of this areas future. Thus this design aims to preserve this natural environmental by redeveloping this site with a minimal intervention strategy. The site in transformed into a nature oriented hotel, where people get a change to enjoy both the natural and build heritage that the site already has to offer. The design aims to have a minimal impact on the existing landscape, on the heritage buildings and on the entire climate. Therefore special attention is paid to designing sustainable by reusing material and applying exclusively sustainable building materials in the process. This way the design balances both the natural and build environment of the site and shows how these do not need to be mutually exclusive in a Heritage site such as Hembrug.
