At the top of Alcácer Castle, this exclusive 1,500 m² property offers absolute privacy among centuries-old olive trees and panoramic views. With prestigious architecture that blends contemporary design with the Comporta style, the villa stands out for its sustainable wooden construction and minimalist window frames, ensuring superior thermal comfort. With 215 m² of built area, the villa is defined by its versatility and is distributed across two interconnected units: the Main House (V2) and a fully independent Guest House (V1). All rooms are en-suite, and the guest unit, equipped with a kitchenette and independent entrance, ensures total privacy for both owners and visitors. The functional layout is completed by an outdoor laundry area and a storage room prepared for electric bicycles. The Main House is designed for social living, featuring an open-plan social area that brings together the kitchen with island, living room and dining room, complemented by an office and pantry. Thermal comfort is ensured by a central designer fireplace, underfloor heating and cooling, and concealed air conditioning, with efficiency guaranteed by solar panels. In the private area, all suites include walk-in closets, while the Master Suite stands out for its luxury, featuring an exclusive patio with both indoor and outdoor showers. The Guest House emphasizes a strong connection with the outdoors, with the living area and kitchenette opening onto a private, shaded garden patio, complemented by a full suite. Absolute autonomy is ensured by its strategic location on two different streets: exclusive access to the guest unit via Rua das Torres, and main vehicle and pedestrian access to the villa via Rua do Castelo. The exterior extends the luxury experience, highlighted by a generous dining area overlooking the infinity concrete pool (12 x 2.8 m), built to the highest quality standards. Functionality is ensured by a carport for two vehicles with electric charging and a discreet lower technical area offering ample storage space for all garden furniture. As the gateway to Alentejo, Alcácer do Sal combines history and convenience: it is located just 80 km from Lisbon and approximately 23 km from Comporta. Crowned by its millennial castle, the town cascades down winding streets to the Sado River, creating a setting of rare authenticity.
