A unique opportunity to create a private residence in the heart of Cascais’ historic center, recognized by UNESCO. This 18th-century manor house is sold with an approved architectural project and municipal permits. The main building preserves original features, including Lioz limestone frames, sash windows, wrought iron balconies, and traditional roofing. The approved project envisions a careful adaptation of the property for use as a single-family residence, honoring the architectural heritage of the estate. The project outlines a main residence spread across three floors, with a layout that emphasizes natural light, spatial flow, and connection to the garden. On the main floor, the manor offers a spacious 66-square-meter living and dining area, connected to the outdoors through a large glazed window that creates a seamless transition between interior and garden. On this same level, there is a second room, ideal for an office or library. On the first floor, the private area includes three complete suites. The master suite spans 50 square meters and features a spacious bathroom and walk-in closet. An additional bedroom may be added in the attic space. This is not merely a renovation opportunity, but an invitation to contribute to the preservation of Cascais' built heritage. The approved project offers 349 square meters of residential living space, in a location where the urban layout of past centuries intersects with the rhythms of life by the sea. In this area of Cascais, the ocean is always close. Praia da Rainha is just a three-minute walk from the property. Evenings can be spent in local taverns enjoying fresh fish, browsing the shops on the pedestrian streets, or watching the sunset at Praia do Guincho. Lisbon is just twenty-five minutes away along the coastal road, with the airport reachable in thirty-five.
