Founders

Seb and Simon founded In Situ in 2015, fuelled by a shared passion to create projects that took inspiration from and provided support to young people across London and beyond. Over the years they have had multiple different collaborators and team members but are currently focussed on growing the studio sustainably to the point of expansion moving forward.

Seb Benson

Having previously worked at Populous for 5 years on the Paris 2024 Olympic Games, Seb has a wealth of experience in large-scale events and infrastructure projects. In addition to his architectural expertise, Seb has always been deeply committed to community engagement and youth outreach. While studying at University of the Arts London, he served as an outreach ambassador, leading initiatives to bridge the gap between creative education and underserved youth. This passion for social impact continues to influence his work at In Situ, where Seb focuses on projects that combine creativity with purpose—whether in stage design, installations, events, or exhibitions.

Simon Keeling

Since going In Situ full-time in 2022, Simon has managed over 30 projects, leveraging his extensive experience and leadership from his time at award-winning practice Proctor + Matthews. Specialising in large-scale developments with local councils and housebuilders, Simon brings a deep expertise in design-to-construction processes. He also oversees the In Situ Homes offshoot, balancing complex projects both onsite and within the studio. Equally passionate about In Situ’s youth-focused mission, Simon has dedicated much of his time to mentoring aspiring architects, musicians, authors, and fashion designers, helping them navigate their creative careers.
