1905 industrial building set to become Acciona’s new office in Madrid

An abandoned industrial building originally built in 1905 is currently undergoing a revitalization project to become a new office building for Acciona, a Spanish sustainable infrastructure and energy company. The Madrid-based building is being designed by Foster + Partners and will include over 107,000-sf of new office space and a unique mix of private and public land with green landscaping.

The building was originally built as a natural gas plan that supplied energy to the surrounding areas and had fallen into disuse until Acciona acquired it in 2017. The project will introduce a series of stepped floors that create terraces sheltered under the historic roof.

The lightweight structure will be made from timber sustainably sourced from local forests. It will allow for spatial flexibility while also integrating lighting, ventilation, and other services within. The timber structure will save over 1,000 tons of CO2 and is recyclable and demountable. A central skylight will bring natural light into the building’s interior, reducing the need for artificial lighting. Silicon plates that generate electricity will also be incorporated.

The project will include a new courtyard (within which is a new ground floor space with a garden roof) that leads to a large 100,000-sf+ park with 300 trees, outdoor working spaces, and areas for informal meetings.

The project is currently under construction.

The Harvard studies on the unintended effects of open office defines it as space where 'one entire floor was open, transparent and boundaryless… [with] assigned seats,' and the other had 'similarly assigned seats in an open office design, with large rooms of desks and monitors and no dividers between people's desks.'
