It is important to us that we have a practice ethos and produce work that is ethical and socailly responsible.

Since qualifying in 2005 Tony Broomhead has been committed to exploring how architecture is made and communicated both in practice and academia. 

Through installations, temporary structures, small projects and many collaborations we have developed an architectural agenda that is about honesty of construction and process, and making spaces that are accessible for all. We set up OS31 in 2014 in my home city of Sheffield with the aim of producing architecture that is informed by context and brings people together.

The practice ethos is fundamentally about people and helping them engage with spaces. The approach actively encourages involvement in the design process to create forward looking architecture for people. We work with a number of collaborators from different backgrounds that contribute to specific projects, making the practice responsive and constantly evolving. As a collective we are committed to developing a social architecture that is buildable, honest and adaptable born out of economic needs and a passion for the profession. TB


The main driver behind our research is to encourage debate and empower the user. We believe by doing this a more resilient architectural agenda can be developed resulting in spaces that are focused on human interaction. Research is completely imbedded within our practice and is a mechanism for testing out ideas. 

Working with NKA we established the Amenity Space Research Project which explores the potentials of digital media as an accessible consultation and communication tool for architects. The practice has engaged with communities and cultural organisations across the UK and has encouraged people from outside of the profession to have an active involvement in the design process.

We have established working methodologies for public consultation and brief building. In April 2015 we released a toolkit to assist architects with the consultation process. This can be downloaded from the project website. amenityspace.net

Our research was recently published in Demystifying Architectural Research by RIBA Books and continues to inform both our design process and academic teaching. TB
