Mathieson Architects is a Sydney-based architectural design studio.

Design Director Phillip Mathieson leads an approach to design that is grounded in Modernist principles of authentic, timeless design and planning rigour. Central to this philosophy is a strong sense of scale, form and material, and an emphasis on finely detailed spaces built to outlast changing fashions.

The firm has gained a reputation as a leading practice whose work has been widely published both in Australia, and internationally. With significant experience in designing and delivering high-end projects across a range of residential, multi residential, commercial and hotel/hospitality sectors, Phillip is supported by a creative and enthusiastic team of architects and interior designers.

Mathieson Architects was awarded at the Australian Institute of Architects ACT Awards 2019 for Residential Architecture – Houses (New) and at the Asia Pacific Property Awards 2013 and 2017 for Best Architecture Single Residence Australia. In 2019 the studio was awarded The Robert Foster Award for Light in Architecture.
