Privacy, space, and energy efficiency in Valldoreix, Sant Cugat Located in one of the most peaceful, exclusive, and highly valued residential areas of Sant Cugat del Vallès, this property stands out for its solid construction, architectural adaptability, and a design meticulously conceived to offer maximum comfort with minimal maintenance costs. An ideal home for those seeking immediate proximity to Barcelona (just 8 minutes through the tunnels) without sacrificing a natural, private, and serene environment. SPACIOUS AND ADAPTABLE SPACES FOR YOUR LIFESTYLE Main Residence (690 m²): Characterized by the great spaciousness of all its rooms and the quality of its fine materials. Notably features seamless Italian Serpeggiante marble flooring selected directly from the quarry. It includes living rooms with fireplaces distributed across various ambiances, a large 33 m² eat-in kitchen with a bright U-shaped glass bay window, and a 63 m² master suite with a briarwood walk-in closet, private terrace, and a spectacular full bathroom that includes a separate shower and a hydromasaje hot tub oriented toward the views of Tibidabo. State-of-the-Art Flexible Architecture: Built with a solid reticular concrete structure without load-bearing walls, allowing for easy redistribution of partition walls as your needs change. The original project already foresaw the structural space for an elevator installation and the technical possibility to independentize the large 168 m² attic (which currently features a living area, bar, cast iron fireplace, and a 33 m² sun terrace), given that its current restroom has sufficient space to add a bathtub. Independent Guest House (110 m²): Perfectly integrated into the plot while maintaining the complete privacy of the main residence. It features its own access from the garden, a living-dining room with a fireplace, a 19 m² porch, an equipped kitchen, 3 bedrooms, and a full bathroom. (Note: Combining both constructions, the property offers a real total of 800 m² built). ADVANCED SUSTAINABILITY AND EXTERIOR ENVIRONMENT Photovoltaic Efficiency and Self-Sufficiency: The property is equipped with a high-capacity solar photovoltaic installation that allows for an optimal net balance (generating as much electricity to feed back into the grid as is consumed). Extraordinary comprehensive thermal insulation of projected polyurethane (7-10 cm) along with PVC enclosures and Climalit double glazing guarantee minimal energy expenditure throughout the year. Mature Perimeter Garden (1,650 m²): Practically flat plot, fully fenced and surrounded by Madagascar jasmine vines. It features an enjoyable swimming pool surrounded by palm trees, a lounge area, a high-flow ancient well as a decorative feature, and an outdoor dining area covered by a tropical wood pergola and an authentic Argentine barbecue. The automated irrigation and the swimming pool are self-sufficiently supplied by a large rainwater collection cistern and the well itself. Facilities and Connectivity: Optimized fiber optic connection for both homes. The basement garage, accessible via a gently sloping rampa, has an ideal capacity to comfortably accommodate 4 cars and several motorcycles, in addition to a workshop area, a centralized vacuum system throughout the house, zone-controlled heating, and a central water softener with reverse osmosis systems in the kitchens.
