The present mansion was re-built in a classical 18th century style on the foundations of an older edifice around 1850. Past the entrance gate leading directly to the main courtyard with a central circular lawn, the mansion comes into view. At the rear of the mansion, parklands planted with centuries-old trees provide the backdrop for a both pastoral and elegant scene that stretches as far as the river.
This four-storey mansion spans approximately 1,200 m². Its slate roof, which is in excellent condition, is dotted with bullseye windows. The edifice extends out on either side of a central south-east facing front section. This houses the main entrance, topped by a wrought iron balcony whose motifs are reminiscent of the Sun King's monogram. The balcony can be reached via French windows framed by a sculpted pediment. The upper part of the front section rests on four columns topped with capitals. On each side of the entrance, two carved stone sphinxes stand guard over the estate. Each wing has a row of five windows per level. On the ground floor, thanks to the dual aspect rooms, they connect the front and rear of the grounds.
At the four corners of the mansion, four square towers emphasise the symmetry of the design. Each tower features windows richly decorated with carved shells and floral motifs in the Renaissance style. The façades of the towers are framed by slender columns crowned with finely crafted capitals. The north-west façade, facing the grounds, echoes the composition of the main façade. Its central avant-corps stands beneath a bullseye window framed by two imposing gable dormers. All of the façades, as well as the slate roof, have been carefully restored in keeping with their original architectural style.

The Mansion

The ground floor
Past the main entrance door, a second interior door provides access to the entrance hall and the grand staircase at the back. To the left, two carved wooden doors reveal a striking view of the various sitting and drawing rooms following on from one another. The first is adorned with Trianon grey painted woodwork, lending a typically 18th century style to the room. Two tall windows on either side provide plenty of light. A large double door provides access to the second drawing room, known as the "Salon des Blasons" (Coat of Arms Room), on account of the four coats of arms sculpted on the ceiling, belonging to the former families who had been masters of the premises. A double door topped by a carved wooden pediment leads to the large drawing room, known as the "Salon Doré" (Golden Drawing Room). The walls are panelled with grey and gold painted woodwork topped by a carved frieze featuring various coats of arms framed by carved greyhounds and adorned with crowns. Two doors leading to the ground floor of the corner towers are crowned by painted oval trumeaux depicting landscapes in the manner of late 17th century Italian paintings, framed by garlands of sculpted flowers held by putti. The four tall windows illuminate the room with natural light that catches the gilding. The dual-exposure sitting rooms follow the path of the sun, and the tall windows offer a view of the grounds and the Essonne River in the distance. Back in the entrance hall, a double door leads to a gallery serving two other drawing rooms and a third, larger sitting room with a Louis XV style fireplace of white stone topped by an overmantel mirror. From here, a small corridor leads to a room in the corner tower of the main facade, to another room used as an archive, and to a staircase in the north-east tower. This connects to the upper floors and to the cellar.
The first floor
Accessed from the main staircase, it is also served by two staircases located in the rear towers. A gallery leads to seven bedrooms, all facing south-east. They have been renovated by the current owners while retaining certain old features such as marble fireplaces, Versailles parquet flooring and mouldings. A double door at the north-east end of the gallery provides access to the mansion's chapel. This neo-Roman style chapel has two levels. It has retained its original decor. A neo-Gothic tabernacle sits imposingly on top of the altar and is guarded by a Virgin Mary emerging from a carved wooden grotto. The walls are adorned with paintings of curtaining and flowers, as well as the coats of arms of the former ruling families. The groin-vaulted ceiling boasts a painted starlit sky with flying doves. Facing the altar, the neo-Gothic carved wooden confessional is topped by a balcony that can be accessed from the second floor. All the original stained glass windows have been miraculously preserved from the ravages of time. On either side of the altar, two large doors with stained glass panes lead to the sacristy. A small corridor provides access to the gallery and to the staircase in the north-east tower.
The second floor
Reached from the main staircase and the spiral staircases in the two rear towers, this level comprises a gallery leading to the eight bedrooms with herringbone parquet flooring. Two of these have en-suite bathrooms. The current owners have started to install a third bathroom. One of the bedrooms has a double door opening onto a balcony with a bird's eye view into the chapel. At the end of the gallery, a small corridor leads to the back of the Virgin Mary statue in the chapel. The triforium with its neo-Gothic ceiling above the altar offers a discreetly hidden view of the chapel.
The third floor
This level is accessed from the main staircase as well as from the spiral staircase in the north-east tower. The main landing, topped by a vaulted ceiling with a skylight, leads to 5 bedrooms in the west wing. A small doorway leads to the east wing, which contains a number of small rooms, as well as a larger room which was originally used as a linen room. A late 19th century pulley block has been preserved. The floors are of terracotta tiles and straight strip parquet. Part of the west wing has been restored by the owners.
The basement
Accessed from the staircase in the north-east tower, they stretch over the entire surface of the chateau. They comprise a large room used as kitchen which needs to be equipped, as well as various vaulted rooms including a utility room.
