An Eco-Luxury A+-Certified Villa Between the Mountains and the Sea Nestled within the protected expanse of the Sintra-Cascais Natural Park, in the prestigious enclave of Zambujeiro, this minimalist single-family villa redefines the concepts of sustainability and exclusivity. A singular estate, masterfully designed for those seeking an absolute balance between the pristine serenity of Quinta do Pisão and the vibrant Atlantic energy of Guincho Beach. - Architecture, Light, and Interior Fluidity Boasting four facades that ensure exceptional light exposure throughout the day, the villa stands out for its clean lines and expansive glass doors that seamlessly merge the interior with the landscape. The social area spans a 655 sq ft (61 m²) open-concept space, entirely south-facing, bathing the living and dining rooms in a vibrant natural light. The gourmet kitchen, equipped with integrated appliances from the prestigious German brand AEG, marries precision engineering with functional design, connecting to or isolating from the living room via elegant, minimalist sliding panels. The main floor also hosts a versatile room (ideal for a home office or guest bedroom) and a guest bathroom. On the upper level, the private wing is distributed across three spacious en-suite bedrooms with independent balconies. The architectural masterpiece is the Master Suite: strategically positioned facing North for absolute privacy, it features a secret courtyard and private garden that, due to the absence of upper levels, receives direct sunlight nearly all day—a true sanctuary of serenity. - The Outdoor Retreat The outdoor living space was conceived for leisure and utmost privacy. Facing South, the private heated pool invites prolonged swims under direct sunlight, flanked by a social deck and a low-maintenance landscaped garden, perfectly tailored to the Cascais climate. - Sustainability and Invisible Comfort Engineered to deliver a net-zero carbon footprint and maximum efficiency, the villa boasts the highest possible A+ energy rating. Virtually self-sufficient, the residence features high-density insulation and premium window frames that create an impeccable acoustic and thermal barrier. Climate well-being is delivered via an invisible hydronic radiant floor heating system throughout the entire home, complemented by state-of-the-art solar systems that ensure eco-friendly heating for both domestic water and the pool. - Strategic Lo
