Seyi joined DSDHA in 2019 after completing her Part II at the London School of Architecture with Distinction. Her thesis project explored how cities like London can better accommodate those displaced by crises, and the networks and infrastructure required to aid their transition. She qualified as an architect in 2022.

Since joining DSDHA, Seyi has worked on a number of projects, such as the Tustin Estate, that utilise meaningful engagement and collaboration to create more inclusive landscapes and urban spaces. Seyi also co-led the London School of Architecture Design Think Tank on Spatial Justice.
