BY Projects Architecture is a Melbourne-based residential practice led by Barbara Yerondais, specialising in heritage restoration, sustainable design, and community housing. With over 35 years of experience and more than 400 projects delivered across Victoria — including 59 heritage overlays and 235+ social housing dwellings — the practice brings deep expertise in navigating complex council planning processes, heritage conservation requirements, and building science. The practice is known for its collaborative, honest approach — designing homes that are liveable, sustainable, and built to endure, not to impress a magazine cover. Whether it’s a heritage rear extension, a second-storey addition, or adaptive reuse of a heritage building, BY Projects brings the intellectual rigour and warmth to get it right.
Our team of architectural specialists offer the following services:
- Assessments of the property to determine whether renovations are feasible.
- Creating designs to help plan the project and apply for relevant permits.
- Extensions and alterations for heritage homes
- Adapting heritage buildings to be reused.
