After being awarded the design and execution project for the refurbishment of its auditorium in Madrid carried out to the entire client satisfaction, Ercer carried out the turnkey project for the design and building of a collaborative area in one of the floors of its Madrid headquarters. The building is located within the Calle Hermosilla complex in the capital city. In addition to informal meeting areas, a training room was established and the central staff dining room was renovated.

Since then Ercer has continued working on different projects with the Garrigues firm. The refurbishment in its study center or the fit out of the offices in Valladolid stand out.
