Ideally located in the most desirable neighborhood of Bonnières-sur-Seine, just a stone's throw from the city center and its shops, this sumptuous millstone mansion is among the city's most beautiful residences. Built on a vast, wooded plot of 1,440 m2, it captivates with its characterful architecture, generous volumes, and privileged residential setting, 40 minutes from Paris via the A13 motorway. With a living area of 311 m2 , the house offers a refined and bright living environment, perfectly maintained. Past the paved courtyard where an elegant fountain sits, the entrance sets the tone: noble materials, fluid circulation and beautiful high ceilings. The ground floor accommodates a vast double reception room of 42 m2 extended by a veranda bathed in light, a more intimate secondary living room, an office, a dressing room and a separate toilet. The kitchen, of almost 20 m2, opens onto the garden and constitutes a real space for family conviviality. The upper floors offer five well-distributed bedrooms, including a suite with bathroom and dressing room, a shower room, a second bathroom to be refreshed, as well as a games area and attic spaces that can be used as needed. A partially converted attic completes these sleeping areas, offering great prospects for expansion or storage. In addition, a full and healthy basement includes a laundry room, boiler room, workshop, cellar and wine cellar, while a large independent garage of over 60 m2 can accommodate three vehicles. At the rear, the west-facing garden offers a rare bucolic setting, punctuated by a century-old maple tree that signs all the poetry of the place. Exemplary in terms of energy, the house benefits from a DPE of B (90) and a GES of A (3) , a guarantee of optimal thermal comfort in summer and winter, without heat loss.
