Esther Stevelink studied at Delft University of Technology from 1992-1997, where she graduated successfully as an architect. She gained professional experience at leading architecture firms such as Claus en Kaan architects in Amsterdam, Geurst & Schulze in The Hague and Van Sambeek en Van Veen architects, also in Amsterdam. At these firms, she worked on a variety of projects, from urban planning assignments to the design of schools and residential buildings.
In 2006, she started GAAGA out of a wish for more direct contact with end users combined with more custom-made architecture. In addition, she focused on research and education, including a guest lectureship at TU Delft. From 2007 to 2010, she was a member of the building aesthetics committee of the municipality of The Hague. In 2015, she was a jury member of the biennial European ideas competition Europan 13 for architecture, urbanism and landscape, for which she and Arie Bergsma won second prize in 2001 and first prize in 2010. She joined the OpenBuilding.co network as a founding partner in 2021.
