Federica also collaborated for three years with the University of Bologna and Italian Local Authorities, mapping assets confiscated from organised crime for studying and designing their social and strategic reuse. 


She is keen to bring social value to any of her designs and experiences. She values the input that every user can bring to inform the design, and she always tries to create and stimulate this interaction in any projects and scales.

Throughout his Masters, Richards’ thesis projects focused on the regeneration of urban spaces, starting first and foremost with the people already populating these spaces. He spent time exploring how the introduction of light industrial spaces and simple alterations to the public realm could reinvigorate the High Street. Following this, Richard’s final year thesis pealed back the history of a 1960s housing estate to address issues overlooked or ignored by previous interventions, explored how such an estate could be enhanced to increase building performance and vastly improve the living conditions and environment for residents.


Richard has worked at a number of small practices across London, working on residential projects at a range of scales. Richard is passionate about sustainable building methods and the adaptive re-use of spaces and materials.


Outside of architecture Richard always like to have a few projects on the go, from knitting a fresh pair of socks for the cold months or spending time down at his allotment.
