Residential building free all around, on a large triangular plot in the heart of the city with direct access to a metro station and the public transport. Unique modern design both externally and internally. Airy and sunny apartments with large openings that make the most of the panoramic view offered by the location of the plot. Innovative design on the facades of the building with stone cladding in the corners and impressive night lighting. The horizontal airy opening on the 5th floor is planted in order to ease the volume. All the areas of the apartments are ergonomic and functional. A building that differs aesthetically from the usual city buildings, with apartments of different typology such as maisonettes with loft type balconies and maisonettes with attics. Every apartment has a parking space and a storage room. The kitchens and bathrooms are specially designed for each owner in collaboration with experienced decorators. The design, the equipment and the construction materials that we use, such as the installed photovoltaic system, the thermal facade 10 cm around the building, the energy frames certified in Germany, the natural gas installation, etc., contribute decisively to energy and money saving while rendering the building energy class A +, based on a K. EN.A.K. study.
