Sharon graduated from Auckland University in 1984 and became a Registered Architect in 1994. Following graduation, she spent 9 years overseas in Australia, Singapore and France working on luxury resort projects. On returning to New Zealand, she worked with several local practices and was exhibition designer for the Museum of New Zealand before establishing Jansen Luke Architects. After the birth of her two children, Sharon joined the practice of Tennent + Brown Architects as senior architect in 2004. During this time the practice won several NZIA Architecture awards for its residential work, including a NZIA NZ Architecture Award for the Leigh House in Northland for which Sharon was design and project Architect. 

In 2013 Sharon was made a Fellow member of the NZ Institute of Architects. Sharon has tutored in Architecture and Interior programmes at Victoria University and Massey University in Wellington. She has served on NZIA Architectural Juries at Local and National level and was Convenor of the National Awards in 2021. Sharon is a member of the NZIA Wellington Branch Committee. She is on the Management Committee for Accreditation of the Architecture Schools for the NZ Registered Architects Board, and a standing panel member for Accreditation procedures.

In 2014 she returned to private practice concentrating on residential projects. The practice focus is to seek elegant architectural solutions for new projects, alterations, and interventions. Her interest is restoration and intervention to existing modernist houses, an era and style she particularly loves.
