House in Mesnil-Roc'h, Ille-et-Vilaine

A Remarkable 17th-Century Water Mill Estate in Romantic Brittany – A Turnkey B&B, Glamping & Event Venue

As you drive up the long, tree-lined driveway, a serene and idyllic setting unfolds before you. To your right, the calm waters of a private pond shimmer under the sky, reflecting the surrounding greenery. To your left, nestled among mature trees, are charming treehouses and the historic main house.

The welcoming atmosphere is enhanced by a hedged parking area discreetly positioned to provide ample spaces for visitors without detracting from the estate’s natural beauty or interrupting the perfect photo opportunities.

Passing the elegant dining room and the beautifully preserved waterwheel, you step into the reception area — a warm, inviting space furnished as a cosy sitting room. The centrepiece is an open fireplace that promises welcoming warmth and comfort, making it a perfect spot to greet guests or unwind after a day’s activities.

A staircase leads down to a vaulted wine cellar, situated directly opposite a private bar and games room. This lower level offers guests a social space for intimate gatherings, wine tastings, or casual games, contributing to the estate’s charm and appeal.

From the reception area, the dining room offers panoramic views over the pond through double sliding doors. This bright and airy space is ideal for hosting large family dinners, group meals, or seminars, comfortably seating up to twelve guests. For accessibility, the adjacent toilet has been thoughtfully adapted to accommodate wheelchair users.

Stairs from the dining room lead to the first floor, where you find two tastefully appointed guest bedrooms. Each bedroom features an en-suite shower room and a separate WC, offering privacy and convenience for visitors. These rooms combine modern comforts with the historic charm of the mill, providing a unique and tranquil retreat.

From the reception area, step outside to the private owner’s quarters. There’s potential to reopen the connecting wall to the reception, allowing for greater fluidity between private and public spaces. Upon entering the spacious lounge, you are greeted by a large fireplace that commands attention as the centrepiece of this comfortable living area. The lounge also features a mezzanine landing, creating an open and airy atmosphere.

Off the lounge is a large kitchen and dining area, fully equipped for commercial use — ideal for preparing meals for guests or private family dining.

An original wooden door from the lounge leads into the luxurious master suite. This suite includes a generously sized bedroom with direct access to the garden and a separate walk-in wardrobe area — designed with both luxury and practicality in mind. The en-suite bathroom is a sanctuary in itself, featuring a jacuzzi bath, double sinks, and a walk-in shower area.

From the lounge, stairs lead up to the mezzanine landing — an ideal space that can serve as a home office, play area, or additional relaxation zone.

To the left of the mezzanine is a bedroom with an en-suite bathroom. This room is versatile and could be transformed and incorporated into the guest accommodation if required, providing flexibility to expand the hospitality offering.

To the right, a corridor leads to two further bedrooms, a separate WC, and a cosy, bespoke shower room. These rooms are finished with care and warmth, maintaining the historic character of the building while offering all the comforts expected in a modern home.

Leaving the private quarters, we continue along the main house to a large ground-floor bedroom, which overlooks the surrounding fields through wide windows. This room features its own fireplace, creating a snug and inviting atmosphere. The en-suite shower room ensures comfort and privacy for guests or family members.

Above this room, accessed by a spiral staircase, lies the final bedroom of the main house. This room offers spectacular views over the fields through an entire wall of windows, complemented by a cosy sitting area and a private en-suite shower room — making it a perfect retreat for rest and inspiration.

Stepping outside, the tour continues through the terrace, restaurant, and bar area, leading to the pool house. This well-appointed space includes toilets and shower facilities for pool users, along with a dedicated room set up for wellness or beauty treatments — adding to the estate’s extensive leisure amenities.

The heated swimming pool is a true highlight, surrounded by a spacious terrace dotted with loungers for sunbathing and relaxation. A charming bridge crosses the pool, leading to a jacuzzi, creating a luxurious water feature that invites guests to unwind. Nearby, a covered area provides versatile space, ideal for additional seating or games, enhancing the outdoor entertainment options.

Crossing over to the marquee, you find a large, heated venue with its own terrace — perfectly suited for weddings and large events. The marquee comfortably seats up to 130 guests indoors. Behind the scenes, a preparation area is available for caterers, along with a large storage space for equipment and furniture. Modern toilets and showers are provided to accommodate guests, ensuring convenience and comfort for all events.

The grounds themselves are a treasure, with four enchanting treehouses offering unique glamping experiences high in the treetops. Two authentic wooden caravans add rustic charm, while two cosy cabanas — one located right on the water’s edge — offer spectacular views across the pond towards the main house.

These unique accommodations provide guests with memorable, immersive stays amid nature.
