who we are

We are a close-knit team who work from our studio in Stokes Croft. The Practice was started in 2007 by Chris Askew and has evolved steadily over the years into the people-oriented place it is today. The practice merged with Cavanna Partnership in 2014.

Along with our core team we like to maintain links with student internship programmes, and as a result our numbers periodically multiply to welcome new faces.

sam whinnett

Sam loves solving problems, and the built environment is full of them.  Whether it’s a tight city plot, fragile natural environment or a rundown shed in need of care, the infinite details that require resolution capture Sam day to day.  From Tasmania, Sam completed the Master of Architecture there in 2009, and has since worked a good few years in offices in Melbourne & Western Australia, as well as a diverse array of building sites.  Before relocating to Bristol, he was working in a furniture workshop for an architect / maker, assisting in both design and making.

Sam undertook the final part of his studies at the University of Bath.  At Askew Cavanna he has become proficient in managing contracts and helping clients and contractors through the journey of the construction stage.  He believes a building can’t be good without being sustainable and has developed a broad and deep understanding of materials and technologies to ensure this goodness. 

Delivering good buildings that are possible for all people requires balancing a multitude of issues; finance, durability, buildability, sustainability, programmes and more, and these keep Sam learning and interested every day.

billy butler

Billy joined the practice in early 2017, bringing a broad range of technical knowledge and and experience in both residential and commercial sectors. 

Central to Billy’s design ethos is that matters of aesthetics, cost, buildability and reduced environmental impact are all considered with equal importance. Key to his design approach is an understanding that successful building projects come about from listening to, and closely collaborating with, the various parties involved, be it client, builder, engineer or consultant.

Billy studied at the University of Edinburgh and Oxford Brookes University before gaining his final qualification at UWE, Bristol. He is a is an RIBA Chartered Architect and as part of his training, he spent a year on site as a trainee carpenter. This experience has given him a deep respect for the skills and knowledge that are found within the construction trades and continues to inform how he works as an architect today.

Billy has a keen interest in sustainable construction methods and innovative approaches to affordable housing, in terms of both design and procurement. This includes custom and self build approaches, co-housing and community land trust models. Outside of the studio he will most likely be found on a bicycle, playing the drums (badly) or listening to music.
