Casal da Mata is located in Serra dos Gaiteiros, in the eastern part of Parque Natural da Arrábida. This property extends from the Ribeiro Corvo at the base to the hilltop, where it has over 300 metres of frontage, with views of Setúbal and Troia, offering a unique opportunity for ecotourism projects with the potential to build up to 500m². The current owners have lived on the property for 35 years. The house was built in the 1990s, with planning approval from Parque Natural da Arrábida. The property features magnificent panoramic views of Palmela town and castle, the windmills of Serra do Louro, and Barris valley, along with extensive well maintained valleys, virgin woodland and olive groves. The remaining rich landscape lends itself to nature walks, equestrian pursuits or biological cultivation. The house was constructed using high-quality methods and materials, including EPS-insulated cavity walls. Due to the clay soil prevalent in Arrábida, the PNA approved a stability project with an underground concrete ring around the house, combined with concrete pillars and beams, ensuring longevity and stability. Sewage systems (solids and greywater) were installed to enhance biological efficiency. A deep well provides high-purity potable water, with two 30,000-litre storage tanks and a legacy water mine in the largest valley. The house underwent renovations in 2016, which included: Improved roof insulation,; Additional wall insulation,; Automatic low-temperature underfloor heating and cooling by heat pump; 250-litre hot water tank with thermodynamic solar heat pump and passive solar panel heating,; Large double-glazed glass doors for enhanced views,; Ventilation Heat Recovery (MVHR) system for continuous ventilation with 90% heat recovery,; Six photovoltaic solar panels with a 2.1 pkW output, inverter, and smart meter; Secure 500m underground electrical connection approved by eRedes.; Low energy LED lighting throughout the house,. This results in an exceptional borderline A/A+ energy certification to new 2021 standard. The property contains two legal ruins of 200 and 70 square meters. According to the 2005 POPNA law, construction is permitted on properties larger than 10 hectares. The necessary data has been prepared for the submission of planning permission to build new houses, including comprehensive topographic surveys and house plans. Access to the property is via the road at the top, with the nearest supermarket (Continente) 7 minutes away in Setúbal.
