In Luxembourg, Austrian architecture firm AllesWirdGut has re-envisioned the site of an obsolete steel mill as an elegantly designed urban park. Leaving the skeletal elements of the the old factory in place, the architects let the site's hidden qualities shine through the new design. From their description:
Seating areas and new trees are concentrated into islands, which leave empty large areas of space and also serve as focal points in this emptiness. Aging-capable materials such as concrete, wood and untreated steel in combination with rough detailing make it possible for the patina of the past to return.
