Extraordinary mansion of 4,000 m² in Sant Just Desvern. Lucas Fox presents this magnificent unique villa, located in the centre of Sant Just, on the main street of the town, but with absolute privacy. Known as Casa Sans, it was built in 1910, following the Noucentista movement of the time. It is currently part of the Inventory of the Architectural Heritage of Catalonia. The estate has a 4,000 m² plot and a built area of 800 m², which is divided into the main house, the guest house, the staff house, a garden with pool and jacuzzi, garage, gym and squash court. In total, it has 9 bedrooms and 9 bathrooms. The house was renovated in 2014, but has preserved the charm and original structure of the villa. The main house sits on elevated ground, facing the Roman fountain, which gives it a solemn and imposing character, which at the same time allows a peripheral view of the entire enclosure. It has 420 m² distributed over three floors. The first has an office-library, kitchen, living-dining room in 2 spaces and a guest toilet. The second floor has the main suite with attached living room, dressing room and bathroom, and three more suites with their own bathroom. On the third floor we find a bedroom with a bathroom and a terrace of 80 m². The staff house consists of 75 m² with two bedrooms, bathroom, kitchen and living room. The guest house is made up of 65 m² with a double bedroom, bathroom, large living room and bar. Moving on, the splendid garden has a large swimming pool, summer kitchen, and jacuzzi. From here, there is access to the fitness room with sauna and complete bathroom, squash court and covered garage with capacity for five vehicles. Finally, we dispose of several recreation areas throughout the entire compound, in addition to the independent chauffeur's entrance with space for more than 12 vehicles. The plot's perimeter is protected by a large wall that provides with great privacy, with the most advanced security system. This one-of-a-kind property is a truly unique opportunity as there is no other that comes close to match its size, beauty, amenities and numerous tax benefits. Listed as Architectural Heritage, it has a substantial reduction in the IBI payment, in addition to being exempt from Wealth Tax.
