Certified Passive House Villa 236 sq.m. (A++) with €300 Annual Electricity Cost The only residence on the island certified by the International Passive House Institute (PHI), built to the strictest German building physics standards. 1. Location: Strategic Accessibility & Privacy Perched on a private hill in Kostos, offering a rare "dual-lifestyle": Immediate Proximity: To the cosmopolitan pulse of Naoussa, the renowned fish tavernas of Ampelas, and the picturesque harbor of Piso Livadi with its "waterfront" restaurants all in just 5-8 minutes. Absolute Privacy: A sanctuary offering a serene 180-degree view of the Aegean—a view that, due to its position and topography, is guaranteed against future construction 2. Thermal Stability & Quality of Life A Passive House actively ensures optimal indoor conditions: Even at 40°C outdoors, the interior remains stable at 24-26°C with minimal AC, providing natural cooling without uncomfortable air drafts. 3. Indoor Environmental Quality & Heat Recovery The Mechanical Ventilation with Heat Recovery (MVHR) system ensures continuous fresh air exchange and full humidity control, while simultaneously filtering out dust and allergens. The system's technical superiority is based on a heat recovery rate exceeding 90%: incoming fresh air is thermally balanced with the indoor air, resulting in a temperature deviation of no more than 3 degrees from the desired room temperature. This process occurs automatically and passively, ensuring ideal hygienic conditions with an operating cost no higher than a standard light bulb. 4. Engineering Precision & Isolation The building’s holistic insulation and certified airtightness (Blower Door Test), combined with certified passive-house wooden frames and triple-glazed windows, eliminate thermal losses and external noise. This structural excellence allows a single outdoor unit to quietly power the small indoor AC units in every room. Furthermore, the advanced solar thermal system provides an abundance of hot water entirely for free. 5. Resource Autonomy & Minimal Luxury Private Borehole: Providing free water for the Infinity pool (40 sq.m.), which offers a view extending from Naoussa Bay to the islands of Naxos and Ios, as well as the 1,300 sq.m. private garden. Bedrooms: 4 Master Bedrooms with en-suite bathrooms and 165 sq.m. of wind-protected terraces. Extra: Roof Garden (Jacuzzi ready), BBQ area, and 4 parking spaces. 6. Investment Value & Construction Philosophy High Yield: The 90% savings in operating expenses translate directly into profit, making it ideal for high-spec Luxury Rentals. Zero Maintenance: Passive construction shields the building’s structure and interior from the corrosion and wear caused by the island climate. Technical File: Delivered with an official PHI Certificate (A+), Blower Door Test results, and detailed consumption data. Philosophy: "We design for today; we build for generations to come. The philosophy of N.A. FRAGKOPOULOS focuses on creating buildings that serve as benchmarks for durability and timeless aesthetics."
