Maziar Adab
In the past 23 years, I planned and designed a variety of projects mostly in the areas of residential, hospitality, environment, industrial, and heritage.
Since I moved out to Canada, I worked hard for some good Design-Build and Consultant companies, took some courses to match my skills with my new home.
In the framework of my previous architectural firm (www.prmn.coom) my team and I designed many exciting, good looking and thoughtful public buildings which gradually gave me opportunities to contribute in the processes of decision making and space planning of several sustainable development projects.
In all the past years, I have been proactively worked and supported the concept of the UNESCO Global Geoparks by designing several visitor centres, rural tourism facilities, and eventually established a unique e-platform to connect businesses within Geoparks.
Between 2015 and 2018 I worked as a JICA Project team member with 30 experts from wide range of disciplines which gave me a first hand overview about sustainable development.
I am currently work with NORR Architects on an important renovation project in Ottawa and am a member of Canadian Association of Heritage Professionals and have an application with the Canadian Architectural Board Certification as a Broad Experienced Foreign Architect.

Presently I work with Architecture 49 on the CENTRUS mega project which is a very unique heritage rehabilitaion portfolio in Canada.
I love to bring my technical knowledge and architectural sense to people’s workplace or home through my designs. It is a great way that I can contribute in the betterment of of my community and being a good role model to my children.
