Read the full description

Le Relais and the Pavillon du Château, discreet annexes of the imposing Château de Grandchamp, cultivate a sought-after intimate atmosphere among the trees of the park. While the imposing presence of the Château de GrandChamp captivates visitors from afar, future tenants may prefer the discretion of these homes facing the forest. Close to the entrance, they enjoy a certain independence and tranquillity while benefiting from the many advantages offered by the estate. In addition to the wooded park, the homes will have private outdoor spaces ranging from terrace to garden. Some terraces of these homes will have an exceptional view of the Château. These outbuildings will receive bespoke renovation, in keeping with what is planned for the Château. They feature remarkable architectural elements such as the turret of the Relais du Château. Designed as true places of sharing, the modern interiors, conceived to respect the preserved historic richness, create a timeless space where each lot is unique. With private outdoor spaces, the homes of the Relais and the Pavillon combine the benefits of quality of life at the heart of nature with exceptional proximity to the town centre. For your quality of life, discover Grand. Private gardens and terraces; landscaped park with kitchen gardens; parking spaces; views of the Château for some homes. The unique features of your homes: 3 colour schemes to choose from, proposed by our interior architect (flooring, tiles for the kitchen and bathroom, a coloured paint finish in the living room). Kitchen optional.

Become a homeowner

Help for your first purchase

Becoming a homeowner with a new-build property is often more accessible than many people think. Depending on your project, several schemes may apply. An adviser will review the options with you.

  • Zero-rate loan (PTZ)

    Depending on your circumstances and zone, the PTZ may help fund part of your main home in new build, interest-free.

  • Reduced VAT

    In certain eligible areas, buying new may benefit from a reduced VAT rate, subject to income conditions and for a main residence.

  • Bail réel solidaire (BRS)

    To become an owner at a controlled price, the BRS separates the land from the building, in the developments concerned.

These schemes depend on your situation and on the programme. No eligibility is guaranteed here: only a conversation can verify it.
