3-bedroom villa with a spacious basement (104 sqm) featuring two light wells, independent entrance and exit, and abundant natural light, built above conventional standards, where the quality of materials, structural engineering, and energy efficiency come together to provide a superior level of comfort, solidity, and sustainability. Located in a former quarry in Cascais, the property benefits from a solid geological base, giving the construction uncommon structural robustness and superior foundation stability. The villa was built using the advanced ICF (Insulated Concrete Forms) construction system, internationally recognized for its high thermal performance, energy efficiency, and structural strength, providing continuous insulation and a stable indoor temperature throughout the year, both in winter and summer. Inside, the partition walls were built using hemp blocks, a high-quality natural material that provides excellent thermal and acoustic insulation between rooms, contributing to a more comfortable, quiet, and healthy environment. This is complemented by natural hydraulic lime-based mortars, a material well suited for environmentally conscious high-quality construction. This solution enhances wall breathability, preventing condensation, mold, and fungus formation, while promoting a healthier and more balanced indoor environment throughout the year. The controlled mechanical ventilation system (CMV) ensures continuous and efficient indoor air renewal. The domestic hot water system, powered by a high-efficiency heat pump, solar panel with water storage during the summer months, air conditioning in all rooms, double-glazed tempered window frames with SolarGuard protection, ensure a high level of thermal and acoustic comfort as well as solar control. The final result is a villa built above conventional standards, designed with environmental concerns in mind and focused on the future. Book your visit today!
