A rare opportunity to create a private residence in the heart of Cascais’ UNESCO-listed historic center. This eighteenth-century palacete is offered with a fully approved architectural project and municipal license. The main building retains original architectural features, including Lioz stone window frames, sash windows, wrought iron balconies, and traditional rooflines. The approved project outlines a thoughtful transformation of the property into a single-family home, while preserving its architectural heritage. The residence is designed across three floors, with a layout that emphasizes natural light, fluid transitions, and a strong connection to the garden. On the main floor, the house offers a spacious 66 square meter living and dining room, connected to the outdoors by a large glazed opening that creates a seamless link between interior and exterior. Also on this level is a second living area, suitable as a study or library, and an open-plan kitchen of approximately 27 square meters, connected to the dining area and a one-car garage. The first floor is dedicated to the private quarters, with three full en suite bedrooms. The primary suite measures 50 square meters and includes a generous bathroom and walk-in closet. In the attic level, an additional bedroom can be accommodated. A separate structure on the grounds, once a fisherman’s cottage, is connected via the garden and designed as an independent unit. The ground floor houses a social area with kitchenette. On the first floor is a full suite, while the second floor includes another bedroom or study, also with a bathroom. This unit is ideal for guests or for generating income through short- or long-term rentals. This is more than a restoration project, it is an invitation to participate in the preservation of Cascais’ architectural legacy. The approved plans offer 485 square meters of living space in a location where centuries-old streets meet the rhythm of life by the sea. In the historic center of Cascais, the coast is always close. Praia da Rainha is just a three-minute walk from the property. Evenings can be spent at local tascas serving fresh fish, browsing shops on pedestrian streets, or watching the sunset from Guincho Beach. Lisbon is only 25 minutes away along the scenic coastal road, with the airport reachable in 35 minutes.
