Miller Moronell Architects was founded in 2018 as a partnership between Leonard Miller and Catherine Moronell, who have been collaborating since 2014. Together MiMo have 12 years of experience on a broad range of projects, from public institutional to private residential work. MiMo is based in Johannesburg.

MiMo is endlessly inspired by the human collaboration that goes into the design and construction process. We strive to build longstanding relationships with clients, consultants, contractors and communites. For us, architecture is the process of design and is not only the product of a construction project.

As urban people, we will spend 80% of our lives inside buildings. It is therefore a given that our design practice is centered on the emotional and physical wellbeing of users and our future.
Catherine Moronell

Catherine has a Masters in Architecture (Professional) from the University of Cape Town and is a registered professional architect with SACAP.
