Excellent property, with a total of 23 rooms, located in Cascais in the Malveira da Serra region, set in a plot of 37,000 m2 in a protected landscape area, overlooking the sea and total privacy. The sale of this unique property includes a set of 4 residential houses, a caretaker's house and two support annexes. The main house, formerly a 17th-century monastery, has a lot of charm and is in good general condition. It offers a pleasant view of the sea and the entire green valley. Main house features: Upper floor: - Entrance hall, four adjoining living rooms with sea and green views, dining room with secular oven, 3 large suites with private bathrooms, two bedrooms, two bathrooms, equipped kitchen and laundry. Lower floor with independent entrance: - Living room with direct access to the garden, guest toilet, a bedroom, and service bedroom with bathroom. Outside, there is an outdoor parking lot for several vehicles, a closed garage for 1 car, caretaker's house and a swimming pool. In the lower part of the land and with independent access, 3 houses of modern lines were built, (in the final stages of finishing) with 2 floors, totally isolated between them, and individual swimming pools with the following typologies: T4, T5 and T6, and respective areas: 249m2, 320m2 and 333m2. Note: The land that gives access and includes these last 3 houses is of great size and offers enormous potential for those who intend, in the future, to make a highlight of the main house and, in this way, monetize the separate sale of each one of them. For those who do not need to detach from the land, this property offers the possibility of residing in one of the properties and monetizing the rest through long-term rental or local accommodation, as this is also a very popular place for tourist purposes. In the remaining extension of the land, it could be interesting to create a mixed development, for example: organic farming, Zen space, events, equestrian use, or diversify with other activities, as this is a very versatile and interesting property. A differentiated property, in an idyllic location for those looking to enjoy and live close to nature and with total privacy, and at the same time, close to everything necessary for everyday life.
