Beyond teaching and practising general architecture, he has distinguished himself as a hospital architect and a healthcare facility planner for well-known local brands such as the Aga Khan University Hospital and AIC Kijabe Hospital to name but a few. In addition to providing consultancy services as an architect at Aga Khan University Hospital in Nairobi, Kenya, he has been involved in the preparation of the preliminary design for the newly opened University Centre Building for the Aga Khan University on 3rd Avenue Parklands.
He is a strong proponent of salutogenesis and works to create health-promoting environments in designs.  He is also familiar with international health building design codes used globally in healthcare facility planning such as the UK NHS facility codes, European HBN, HTM, American FGI, NFPA and other health and safety codes. His area of strength as an architect is design coordination between the architecture deliverable and the engineering building services for hospitals.
