Agenda 21 Architects Studio is a design-led RIBA Chartered Practice that has been operating from Clerkenwell for the past twenty years, helping clients and businesses improve the way in which we build, live and work.


The practice offers a comprehensive range of services in the fields of architecture and urban regeneration, with emphasis on community and recreation buildings as well as residential developments, hotels and medical facilities.


We have developed a reputation of working successfully in partnership with community organisations, through understanding the particular needs of each social group and assisting them in the challenges they face in turning their aspirations into reality.


Agenda 21 also work closely with developers and private clients to craft inspired, optimised and cost-effective solutions which are also at the same time practical, elegant and of exceptional quality.


Put simply, we are committed to adding value to our clients' assets.
