A gateway flanked by a caretaker's house and a small annex gives onto a drive that leads to the château and its grounds.
Louis Marchal, an architect from Laval, built the château in the early 20th century for the Marquis Robert de Négroni, owner of the neighbouring former ropeworks. It stands on the site of an earlier house. It is built of sandstone and granite rubble stone under a slate roof and has around 480 m² of floor area on four levels.
Its neo-Gothic architecture is a composition of differentiated massing and rooflines. Corner turrets are capped with pepperpot roofs, chimney stacks stand in groups, and dormers have Gothic pediments. A cross and a weathervane top a small bell-turret.
The château stands on slightly higher ground above the Mayenne, on an east-west axis, and overlooks the grounds, which slope down to the river.

The château

It has a main building under a gabled roof, its rectangular plan broken by a projecting section at the south-west corner. The secondary blocks differ strongly from the main building in massing and roofing.
The entrance, on the south side, is recognisable by its hipped lean-to and a polygonal tower containing a winding staircase with a return flight. On the north side, another square stair tower is topped by an upper room decorated with false machicolations. A hipped rectangular block stands beside it, and a small terrace lies hidden between the two. The octagonal central projection on the west side is topped by a further terrace bordered with crenellations.
The openings have surrounds of dressed beige granite with rough rustication.

The garden-level floor
It is partly below ground and has two separate entrances. It comprises a combined sitting room and library, a recently renovated kitchen open to a central island, a separate lavatory, and three other rooms, one of which serves as a boiler room. The flooring is polished concrete.
An oak main staircase with a straight flight retains its railing with turned balusters and its stringer with diamond-patterned panels. A service staircase housed in the north turret also leads to all the levels.

The ground floor
The sitting room has a ceiling with exposed beams and joists painted green, and a carved stone fireplace with columns and capitals. Its tall openings are protected by Art Nouveau stained glass, whose polychrome floral motifs cast coloured light into the room.
The dining room continues on from it, with a limestone fireplace and a coffered ceiling. Light comes from a large opening backed by stained glass with diamonds and cabochons. The windows of a small sitting room and a study are also fitted with stained glass.
The octagonal central projection is glazed entirely with Art Nouveau windows. Its floor is paved with a marble mosaic with fleur-de-lis motifs, and it opens onto the grounds at ground level.

The first floor
A corridor leads to four bedrooms, a shower room with a lavatory, a bathroom, and a kitchen. As on the garden level and the ground level, the service staircase is accessible from this level and leads to the other levels of the house.

The second floor
This level comprises a combined bedroom and sitting room, two further bedrooms, a kitchen, a bathroom, a lavatory, and access to the north stair tower. The tower leads to a small terrace and an attic that runs across the building's footprint.

The caretaker's house

It measures around 70 m² and is fully self-contained, with separate water and electricity meters, but still needs restoration. A garage of more recent construction stands nearby.

The park

They cover a total area of over 5 ha and are dotted with large ornamental trees, with an open view east from the château. They slope down from the gravelled terrace to the river, where a small beach has been created.

The grounds also include two wells and a boat shelter at the water's edge. A small building opposite the caretaker's house, across the entrance to the property, can serve as a storeroom.
