After La Prairie, The Oasis House unveils La Source: three stone houses nestled in a lush 8500 m² estate in Essonne. On the agenda: garden, swimming pool, Nordic bath, and above all, countless walks. We are more than happy to embrace the greenery!

"It is a house that offers great peace, with refined elegance, perfect for enjoying good times."

Around Paris, there are still peaceful villages where time seems to stand still, like Chalo-Saint-Mars. This charming village is home to about a thousand residents who enjoy the fresh air while being close to the capital. La Source provides a comfortable retreat for large groups of friends and families, offering 15 bedrooms with private bathrooms and a total of 28 beds. By the pool, you can enjoy the nearby La Chalouette river, which inspired the house’s name. Whether for a weekend getaway, a vacation, or a seminar (as it is fully equipped), La Source is the perfect spot to relax in complete privacy, with all services included!

Back to basics…

Welcome to La Source !

Welcome to La Source !

Camille Personnat, founder of The Oasis House, envisioned this project of countryside houses with a clear goal: ‘to revive conviviality at work and reinvent team stays in a green, invigorating setting.’ While the homes in The Oasis House collection do welcome workers seeking a natural retreat, they also cater to travelers. By striving to pamper even the most demanding teams, Camille has created a setting that rivals the most beautiful vacation homes.

Originally, there was a typical countryside house that charmed Camille. To give it a new lease of life, the duo enlisted the help of the architecture firm Label Experience. They reimagined the visual identity of the place, incorporating curves and roundness into the furniture and architectural details. Camille’s unwavering involvement, combined with her seasoned entrepreneurial skills and love of beauty, infuses the place with a calm and serene atmosphere.

The lime paint and colors—terra cotta and beige—create an ambiance reminiscent of Provence, just an hour from Paris. The furniture, inspired by Scandinavian zen and sourced from Ethnicraft, the lighting from Original BTC and Jo Sayeg, and the bedding from Bonsoirs, have all been carefully selected.

"It feels like Minorca, it's very exotic."

A stay that’s meticulously
taken care of

The icing on the cake is that The Oasis House offers a plethora of services, ensuring guests can simply enjoy their stay! For budding yogis, the program includes a Nordic bath, sunrise yoga classes, and even a session of ‘sound therapy,’ a sonic journey with singing bowls that provide relaxation and serenity. For those who prefer a more active vacation, there’s ping-pong, foosball, karaoke, and the Nintendo Switch!

In both cases, there’s no shortage of entertainment: horseback riding, yoga, brewery tours, painting workshops, reading under the shelter… To explore the area, about fifteen bikes are available. It’s an opportunity to ride to the French Gâtinais Regional Natural Park for forest walks or to paddle up the river to the picturesque village of Chalou-Moulineux.

The cornerstone of a successful stay? Eating well and sleeping well! At La Source, chefs are available to prepare seasonal and local dishes, as well as tailor-made meals based on the day’s activities and cravings, such as picnic baskets and aperitifs. There is even an on-site grocery store. You can grab a cookie to replenish your energy after a swim in the pool or a game of foosball. For amateur cooks, recipe cards developed by Chloé Charles are available, and groceries can be pre-ordered based on the chosen recipes. Additionally, you can hire a private chef to prepare local and seasonal dishes.

For sleeping, The Oasis House has introduced a unique concept: the pillow bar. Each guest can choose a pillow specially designed to suit their physiological needs and preferences. It’s like being at home, but even better!
