Tanya Awadallah

Tanya has a broad architectural background and over a decade of professional experience. As Practice Manager she works closely with the Principals and Directors developing and implementing systems and strategies that cater for our ever expanding practice.

Tanya has an invaluable understanding of practical building requirements and solutions, and her innovative documentation skills are a result of her considerable experience in the engineering and construction sectors. Her key responsibilities at MHNDU include managing operations, human resources, marketing, communications and our externally audited QSEMS.

She is passionate about MHNDU’s role both as an innovative design practice and a force for positive social change in the community. To this end, Tanya conceptualised the generous and historical office garage as a potential space for a profit for purpose cafe, selling coffee and exhibiting art by local unrepresented, emerging and disadvantaged artists, winning an internal staff competition for her ingenuity.
