Starting point for the young Belgian architects were traces of a nearby former stronghold. The main design element consists of an enclosing wall with a recessed rising part, to which the modest and sober main house nestles and adapts.

The architects chose light grey precast concrete lintels as a reinterpretation of the old fortress walls of rubble stone. The relief of the oozing courses of grout reinforces its rough character. All three remaining facades are clad with dark grey fibre cement panels. The asymmetric roof features a deep-set window facing out to the south.
