Michál studied architecture in South Africa and moved to London, setting up Walters & Cohen with Cindy Walters in 1994.
Michál's many completed projects include a wellness centre in the depths of the Bank of England, a gallery in Durban and the refurbishment of Boathouse 4 in Portsmouth. She is also responsible for many of the practice's education projects, which began in 2003 with designs for an exemplar primary school under the Department for Education's Schools for the Future initiative. Since then, she has visited and researched school design in Italy, Scandinavia, Australia and South Africa to understand best practice in a wider context. She takes a keen interest in government initiatives and policy, as well as how children learn, and her expertise on the subject of design in learning environments is now well established.
Several innovative schools have been completed based on the principles of the exemplar, which were reviewed and revised in 2012 for the multi award-winning Lairdsland Primary School in Glasgow. Current projects include a major new teaching building at St Paul's School in London, and an Innovation Centre for Somerset College in South Africa.
In 2012 Cindy and Michál were awarded the inaugural AJ Woman Architect of the Year Award and have been on the judging panel of subsequent awards. Michál is one of the Design Council's Built Environment Experts. She regularly examines and lectures at universities, speaks at conferences and judges awards. She is also a trustee for Portsmouth Naval Base Property Trust and a member of the Design South East panel, the London Legacy Development Corporation and the Camden Design Review panel.
