Lusail is a new coastal city located about 15 km north of the city center of Doha in Qatar. It has marinas, residential areas, resorts, commercial and entertainment districts, and luxury shopping facilities. The corner plot, on which the Eco-V2 House was designed, is located in the residential district zoned for Qatari nationals. The owner approached M2H Studio with a detailed list of program needs and requirements, along with strict instructions to build a high-end, sustainable, durable, and low-maintenance house. The architect was required to design in a manner that honored the natural environment and culture, lowered energy use, and followed the Qatari sustainable building code (QSAS). The result was integrates two V-shaped components to create two interlocked courtyards that merge in the basement level to promote air circulation. This house is comprised of a half-basement, an elevated ground floor, and first-floor and penthouse levels. The basement contains a lap pool, gym, and private living space. The ground level houses reception space, service quarters, guest rooms, and a Majlis. The first-floor quarters are dedicated to the four children, while the strategic penthouse remains for the parents. In order to respect the family's privacy, the views from the house are almost entirely introverted within the designed courtyards. Views are directed to the reflective pool on the ground level, the flowering tree centralized near the entrance, the pool in the basement, or the landscaped terrace on the penthouse floor. Special attention was paid to the external envelope of the buildings, which have 50 cm sandwich-paneled walls. The density and efficient insulation used within these walls achieves a high thermal resistance value that protects the house from heat gain and reduces the dependency on air conditioning units throughout the year. Thermal solar heating is designed on the roof, in order to supply hot water for the building. Besides, two wind turbines are located on the north eastern part of the plot to feed the entire outdoor and landscaping electrical need. The designer tried to maximize windows facing toward the courtyard and minimizing windows on the east, west, and south external shell. All windows are double-glazed with low-e filters and movable aluminum shading devices. Significantly, the Eco-V2 allows for north winds to circulate underneath the building, be cooled by the reflecting pool and basement pool, and then rise from the back court. This achieves a highly effective passive cooling system for the house, especially the main living space in the basement level. Residents of the Eco-V2 Villa can rest assured that they will live in a positive, eco-friendly, and healthy environment.
