Sancal and Lucas Muñoz have designed the interiors for CoLab, a creative labatory in Madrid, Spain.

CoLab is a collaborative project by Sancal and Lucas Muñoz Muñoz where, together, they transformed part of Madrid's first modern office building, O'Donnell 34, into a creative laboratory.

"Designed in 1966 by pioneering architect Antonio Lamela, it was both an honour and a challenge," said Sancal. "His son, who continues the practice, lent his support."

By carefully stripping back decades of fittings – more archaeology than architecture – Sancal and Muñoz reinterpreted part of Spain's first modern office building, reflecting deep respect for the building's history and commitment to social inclusion.

As a result, any material that could not be recycled remained.

This project has been longlisted in the sustainable interior category of Dezeen Awards 2025.
