Foster + Partners reveals design for a new office building that saves more than 1,000 tonnes of CO2

Spanish sustainable infrastructure and energy company, Acciona’s new office building aims to be a model for sustainable development. Developed by Foster + Partners, the proposal is revitalizing an abandoned old industrial building built in 1905.

The 10,000-meter square building will revitalize the surrounding area by creating private and public plazas on the ground floor and creating connections with the adjoining Méndez Álvaro metro station.

The original structure was used as a natural gas plant that supplied energy to the surrounding areas. It was left abandoned until Acciona acquired it in 2017. With a wish to create an outstanding example of sustainable development, this refurbished building will conserve 10,000 tonnes of bricks and refurbish the original building envelop. The use of timber creates a lightweight structure that is recyclable and demountable, saving more than 1,000 tonnes of CO2.

Nigel Dancey, Head of Studio, Foster + Partners said, “This project offers the rare opportunity to give this magnificent building a new lease of life. It is a great example of Luis de Landecho’s early twentieth-century work, and our design aims to retain its original spirit while creating a workplace that is flexible and adaptable to new and emerging ways of working. Together with Acciona, we have developed a design that is underpinned by our shared vision of sustainability and demonstrates our commitment towards the environment.”

The new design uses timber as the primary building material, which creates a lightweight structure and lowers the overall carbon footprint of the development. Inside the building, the architects have created a series of stepped floor under the historic roof. To improve the productivity and well-being of people inside, the material palette combines natural materials with indoor greenery to create a biophilic environment. A central skylight also fills in the office interior with ample natural light, reducing the need for artificial lighting.

The project takes advantage of Madrid’s temperate climate and proximity to public transport to create a 10,000 square-metre park with 300 trees with outdoor working spots and informal meeting spaces. It also includes a new courtyard within which is a new ground floor space with a garden roof.
