Luxury villa in Las Colinas Golf, Costa Blanca Property located in the Mimosa community, Las Colinas Golf & Country Club in Dehesa de Campoamor. It offers 3 bedrooms and 4 bathrooms with a designer pool and many special features. Situated in the second line of the award-winning golf course and within walking distance of the clubhouse and all available amenities. Built on two levels with ultra-modern features and facilities that have earned it a "green certification," making it an eco-friendly villa and a unique concept in the complex. Pebbles House breaks conventions and creates surprises with unexpected perspectives and unique experiences. "This home is both intimate and versatile, full of identity. A place where art and everyday life constantly intersect, creating an emotional and familial space," says the company. In the semi-basement, curved retaining walls shape the interior, exterior, and pool spaces in an exercise to minimize the weight of the structure by using form to increase energy transfer through the surface in contact with the exterior. These sinuous spaces explore the experience of living inside a pebble while acting as an energy accumulator. On the level above the Pebble (main structure of the house), the living room, kitchen, and pool program unfold in a habitation between technical volumes with retractable joineries, where the experience of outdoor living is felt on different planes: interior, semi-exterior, and exterior. Above the Pebble, a pavilion with a thick wire structure houses the bedrooms and private spaces. With a 45° rotated arrangement relative to the structural grid, the rooms overlook the outside through two large openings, allowing each one to have two different orientations. Both joineries and blackout panels slide along the facade, offering a range of situations from a completely closed envelope to one where the floor opens to the outside by 50% of its surface. The main energy source is electricity generated by photovoltaic panels. Among different renewable energy sources, photovoltaic solar is considered the most efficient, integrating 40 m2 of photovoltaic panels on the building's roof. The solar panels capture solar energy, transforming it into electricity; geothermal probes exchange energy with the deep stratum, with stable temperatures throughout the year, increasing the efficiency of other exchange systems such as aerothermy and reducing equipment maintenance while improving durability by allowing the entire air conditioning installation to run inside the house, protected from the sun and corrosion. The heat recovery ventilation system maintains indoor air quality through constant renewal of clean air and extraction of stale air, ensuring a temperate climate and adapted humidity throughout the year, without loss of efficiency of the heating and cooling system. At the same time, the proposed closing system, with large retractable glazed openings, allows the transfer of the outdoor living experience to the house during the temperate hours of much of the day. The external protection of these openings, through automated sliding louvers, reduces the transmittance (U) of the facade during excessive sunlight hours and when the temperature drops at night. The mixed concrete and wood structure has advantages over exclusive wood or concrete solutions: it allows for composing a diaphragm of great resistance by reducing the weight of the exclusive concrete solution and reducing the volume of the structure compared to exclusive wood solutions, in response to the seismicity characteristic of this geographical area. The wood used comes from sustainable forestry, i.e., from forests grown and exploited according to ecological criteria, which are also located in a nearby environment - Km0 - to the plywood factory, reducing transportation costs and CO2 emissions. 'Green' certification is the distinction awarded by the Green Building Council Spain (GBCe) to recognize sustainable constructions, including social and economic aspects. At the base are the principles of bio-architecture, and the building must be constructed respecting the environment, compatible with the surroundings, and with high levels of comfort and quality of life for users. The Valoriza Seal, awarded by the independent consultancy CoCircular, distinguishes companies in the construction sector committed to the environment, wanting to reduce their impact and improve the management processes of their waste, verifying metrics. This seal certifies the percentage of construction waste valorized and the quality of the complete waste management and treatment process.
