This exceptional Bauhaus-style villa in Heikendorf-Kitzeberg combines modern architecture, exclusive living comfort, and maximum energy efficiency. Located in close proximity to the Kiel Fjord, the property offers breathtaking water views and a forward-looking, sustainably designed living concept.Built in 2011 using solid construction methods and meeting KfW-70 standards, this detached single-family home has an energy consumption of just 19 kWh/(m²·a). Its A+ energy efficiency rating confirms this exceptionally low energy consumption even including the heated swimming pool. Heating is provided by a modern geothermal heat pump with a deep borehole, which draws approximately 75% of the heating demand directly from the ground. This ensures consistently low operating and heating costs and independence from fossil fuels.A high-performance photovoltaic system with a capacity of approximately 12 kW is installed on the roof, generating significant annual electricity. This system can be switched entirely to self-consumption if needed, making the house even more energy-efficient. An 11 kW wallbox for electric vehicles further emphasizes the sustainable nature of this property.Generous, triple-glazed wood-aluminum windows with security fittings, an intelligent shading system with external louvers, and the consistent southwest orientation ensure optimal use of solar energy while simultaneously providing controlled thermal insulation. The overall energy concept is rounded off by a comfortable ventilation system with heat recovery, which continuously supplies fresh air without energy loss.A particular highlight is the energy-efficient spa area. The swimming pool with its infinity pool, counter-current system, and bio-sauna is used year-round, yet achieves an energy consumption comparable to that of a conventional living space. This is made possible, among other things, by additional insulation, a cover to minimize evaporation, a dehumidification system, and the use of a geothermal heat pump to heat both the water and the space.Approximately 293 m² of living space is distributed across light-filled rooms with a well-designed floor plan. Floor-to-ceiling windows harmoniously connect the interior and exterior, creating an open and modern living experience. High-quality fixtures and fittings, a KNX bus system, underfloor heating, individual room air conditioning, and a fiber optic connection complete the technically sophisticated overall concept.The approximately 625 m² property is designed for easy maintenance and complements sustainable living with a robotic lawnmower, a spacious wooden terrace and other functional outdoor areas.This property embodies luxury, high-tech features, and uncompromising energy efficiency. It is ideally suited for discerning buyers seeking a modern home with minimal operating costs, future-proofing, and an exclusive location on the Kiel Fjord. Move in, feel at home and enjoy energy-efficient living for years to come.
