Mark Potter
Director
Mark is one of our founding partners. He completed his architectural training at Cambridge University and has now worked in the business for over four decades. Since opening the doors to Potter & Holmes in 1987, Mark has designed and built hundreds of very successful projects, which reflect his extensive, diverse experience in the field.
Mark co-directs the London office and has always championed the practice’s personal, collaborative approach to client work. He has a particular interest in architecture with a social purpose and he focuses on what he calls ‘Havens of hope’ – property for those in need – and affordable starter homes.
When he’s not at work he spends time with his family in SW London and deep sea diving.

“We have a duty as human beings to tread softly on the ground we have been given, to use our resources efficiently and to inspire and delight where we can with our creativity”

Key Projects
Polly Church
Director
Polly co-directs Potter Church & Holmes’ London office working primarily on the medium to large scale projects and is a key player in the practice’s focus on finding truly innovative and creative design solutions. She is highly accomplished at the design and delivery stages of a project, working closely with clients to come up with imaginative schemes, often to tight budgets.
Polly has taught architecture at Greenwich and Westminster universities and prior to Potter and Holmes worked on large infrastructure and commercial projects for Foster and Partners. Before qualifying as an architect in 2000 from The Bartlett (UCL) Polly took a degree in German at UEA. Speaking fluent German, she has lived and worked in both Germany and Austria and still indulges her passion for 20th century German & Austrian literature. Her must read novel would be Austerlitz by WG Sebald. Outside of work she spends time with family and playing tennis.

“Great architecture is a process of collaboration influenced by the character of a place and its physical, social and cultural conditions.”

Vruti Parmar
Practice Manager
Vruti is the Practice Manager, having worked as an architectural assistant for 14 years on residential, commercial and educational projects alike. Her understanding of project management and the architectural process gives her the tools to keep the practice firmly on its feet.
During her studies at Kingston University, Vruti developed a rather unusual interest in how residential developments incorporated crime prevention, with her dissertation focusing on the extent of which design can influence the level of crime.
When Vruti has spare time away from being a mum she enjoys running and yoga. She has a good few 5K runs under her belt and her next challenge is to up her distance to 10k and beyond. She is also passionate about food from around the globe – both cooking and eating it!

Sara Jarman
Finance and HR Manager
After years working as an IT Project Manager, Sara joined Potter Church & Holmes’ London office as Practice Manager in 2010. Her role is wide and varied, but with the emphasis often on the financial side of the business, she keeps a close eye on the practice’s bottom line.
With her children growing up and becoming more independent, Sara has been able to indulge in her own interests and hobbies. A keen rower, she is often to be found sculling up and down the Thames, as well as walking alongside the river with her large, energetic dog, Griff. She also loves photography, tending her allotment and has an, as yet, unfulfilled ambition to speak French fluently.
