8.5 room Detached house in Seengen

Description
There are houses that impress and those where you already imagine staying when you enter!
This 2026 built 8.5-room villa combines modern architecture with a warm living feel, high-quality materials, and a well-thought-out floor plan. On three floors, it offers space for family, guests, retreat, and the beautiful sides of life. Located on a sunny south-facing slope, on a 640 m² large plot of land, the view stretches over the lake to the mountains.
The centerpiece? An open living, dining, and cooking area that makes generosity tangible. Here, cooking, laughing, and long conversations turn an ordinary evening into a special one. The architecture provides the framework, life fills it.
Additional rooms create space for different life plans. Three bathrooms and a separate guest bathroom ensure comfort, the fitness room in the basement provides movement in your own home. A personnel lift connects all three floors.
Even the technology fits into this claim: geothermal heat pumps, underfloor heating, and controlled living room ventilation create a pleasant indoor climate. The Loxone Smart Home controls, among other things, light, shading, and individual room regulation. Keyless access, video intercom, alarm system, and video surveillance, as well as a photovoltaic system, complement the equipment.
And outside, living continues. The private pool with counter-current system and integrated whirlpool makes the garden a favorite spot. A 30 m² large terrace, a total of 31 m² balcony areas, and covered seating areas offer space for the first coffee in the morning sun, relaxed afternoons, and evenings that can last a little longer.
A parking possibility with prepared e-mobility infrastructure, a cellar, and a storage room complete the offer.
The Seetal region combines this living quality with short distances to shopping facilities and schools, good public transport connections to Lenzburg, and recreational areas around Lake Hallwil. The train station and Lenzburg motorway access are within a short distance.
