YRM (Yorke Rosenberg Mardall) is no longer in business.
It provided architectural, interior design and urban planning services from their London office and partner offices across Europe.
It was founded in 1946, and worked within the evolving modernist tradition with an emphasis on simplicity, integrity and quality. Work covered sectors including:
Airports - Airport planning and terminal design
Corporate - Office buildings and campus planning
Healthcare - Hospital buildings and campus planning
Industrial - Logistics and technology buildings and estate planning
Lifestyle - Arts, hotel, residential and retail buildings and estate planning
Science and Technology - Data, new media and pharmaceutical buildings and estate planning
With sadness, the global recession of 2010, followed by natural + industrial disasters elsewhere in the world brought an end to YRM's projects and it was sold to RMJM in 2011.
