Arturo Soria 343 (AS343) is an exclusive office building recently renovated, which is located in the heart of Pinar de Chamartín, one of the most important business areas in the capital, with headquarters of large companies, both national and international, and with excellent communications by both public and private transport. The building has a total area of 6,620.92 m2, spread over 13 floors. The comprehensive reform of the new AS343 has given it a renewed and distinctive image, inspired by an organic architecture that integrates natural elements with a stimulating work environment equipped with bright, flexible and sustainable spaces. The building connects to the environment by expanding the wooded area and restructuring its private green areas for the exclusive use of tenants. First of all, the general intervention that has been carried out on the façade of the building is striking, with an external truss that increases the level of transparency and interior luminosity while protecting against solar radiation. This second skin improves the energy efficiency and comfort of AS343, while giving it a renewed image and distinctive personality. The construction of a new double-height lobby adds another differentiating and representative element that surprises with its fantastic sense of spaciousness and its careful treatment of light. Inside, the building houses large floors with great natural light coming from its three facades. Its spaces and offices enjoy excellent renovated technical equipment, with sectorized VRV air conditioning, LED luminaires and automatic consumption optimization programs. It has adapted toilets for people with reduced mobility on all floors and a video surveillance system using bullet Domo and analytical cameras. It has a car park with 113 parking spaces with 20 fast electric charging units and consists of 3 high-speed elevators. In terms of energy efficiency and sustainability, AS343 has the BREEAM and LEED Gold labels. The LEED seal certifies the efficiency in the use of water and energy, as well as the implementation of sustainable mobility and innovation policies. For its part, the BREEAM seal is one of the most demanding real estate sustainability certifications in the world that seeks the construction of more sustainable buildings, both to reduce environmental impact and to achieve the greatest possible well-being for users. Another element that distinguishes the new AS343 is its spectacular private roof terrace located on the 13th floor. The new space is unique, dynamic and extraordinarily versatile. It is accessible by an elevator for exclusive use and allows users privileged views and fantastic possibilities for holding afterwork events, meetings, etc. As far as access by public transport is concerned, the building is 400 meters from the Pinar de Chamartín metro station and is also accessible by suburban and light rail, since it is only a 10-minute walk from the Fuente de la Mora station.

As for the environment, the building is strategically located in a quiet residential area of the Costillares neighborhood, surrounded by wide avenues and garden areas.
