Courtonne's design was highly original. Rising from a broad terrace, the main residence, a two-storey building crowned by a balustrade, comprises two suites of rooms. Access from the street is gained by a portico ornamented by columns. This archway reveals the main courtyard, bracketed by two low wings of offices and outbuildings, to the right of which are situated another courtyard, the stables and the kitchens. The façade is broken by three advances. Those to the right and left house the staircases, while the central pavilion displays a magnificent balcony sculpted with lion motifs. Visitors' admiration is drawn by two singular architectural features: the segmented cupola of the entrance hall and, to its right, the first room to have been originally designed for dining. The façade seen from the garden runs the entire length of the buildings, concealing the main courtyard and the servants' yard. Although the design results in a slight imbalance in the natural disposition of the mansion, it respects the placement of a central pavilion with three panels surmounted by a broken pediment bearing the arms of the owners.
