Ellen Van Loon is an architect at the forefront of her field. Alongside six partners, including Rem Koolhaas and Reinier de Graaf, her work at the Dutch architecture practice, OMA, has encompassed some of the most iconic modern buildings in the world, including the award-winning Casa da Musica in Portugal. Two of her projects, The Rothschild Bank headquarters and Maggie’s Centre near Glasgow, were recently nominated for the RIBA Stirling Prize. She joined the practice in 1998 to lead the design for the headquarters of Universal Studios in Los Angeles. Her specific expertise lie in the balance of business acumen and an in-depth understanding of all technical and operational aspects. Here we profile Ellen, with The Rothschild Bank as a backdrop, learning about the strong bond that forms between architect and building.
