For the transformation of the farmhouse into a residence, Govaert & Vanhoutte accurately cuts away non-valuable traces. Valuable historical constructions are thus brought into equilibrium with the scarcely added volumes. One wing of the U-shaped plan of the reduit of the Leopold fort is extruded to the north with office spaces which continue the building not only in plan, but also in sectional proportions. Out of this respectful continuation results the choice of material.
