Family Villa
Located in the heart of Grand-Lancy, this 9-room family villa benefits from a plot of 771 m² and develops approximately 402 m² of usable space, including two levels of 171 m² as well as about 60 m² of converted attic space.
The ground floor offers a bright living room with a fireplace and very beautiful ceiling heights, open to the garden and the terrace. The sleeping area includes three bedrooms, two shower rooms, and a guest toilet. An adjacent garage-box and two outdoor parking spaces complete this level.
The converted attic accommodates three additional bedrooms, a bathroom with a bathtub, and storage space under the slope.
The basement has been converted into a true leisure and service space: a multi-purpose room with a kitchen, a home theater, a gym, a wine cellar, and a shower room. This set offers many possibilities of use, between play area, reception, office, or independent space.
The villa is equipped with a heat pump, solar panels, and a fireplace. Its private garden, modular volumes, and configuration of six bedrooms make it a particularly suitable property for a family seeking space in the immediate vicinity of Geneva.
