Hamzah Mansoor

Graduate, B.Envs (MELB), M.Arch (MELB), RAIA.


Hamzah joined our team at BY Projects Architecture towards the end of 2017. He is an Architectural Graduate from Melbourne University, with an innate passion for design that responds to society and the environment. Since completing his postgraduate degree, Hamzah has developed a strong interest in atmospheric architecture; curating spaces that can create and evoke multiple layers of emotion through form, materiality and the intangible elements. These are the qualities he carries as a designer, which are often reflected in his architectural projects and design competitions.

Prior to BY Projects Architecture, Hamzah has worked as part of the design team in a boutique architectural firm in Singapore. He has gained valuable insight to architectural design, working on multiple design competitions and developing 3D models for a variety of projects. Hamzah intends to broaden his scope of knowledge in architectural practice at BY Projects Architecture. He wishes to be a registered architect by the end of 2020.
