BY Projects Architecture is a Melbourne-based residential practice led by Barbara Yerondais FRAIA, 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. Barbara is a Fellow of the Royal Australian Institute of Architects, registered in both Victoria and Queensland, and a former lecturer in construction and property at RMIT University and the University of Melbourne. BY Projects operates on a fixed-fee model, offering clients cost certainty from the drafting table through to completion. 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 in Albert Park, a second-storey addition in Hawthorn, or adaptive reuse of a heritage building, BY Projects brings the intellectual rigour and warmth to get it right.  

BY Projects Architecture offer a range of services, from early Feasibility Studies through to Construction, complete with total Project Management. We are committed to a social purpose; and through the coalition of technical, aesthetic and economic forces, we seek to provide innovative and sustainable solutions. We endeavour to ensure that our designs are brought to completion on time and on budget.  

Our designs are a response to both the client’s aspirations and the site conditions, with an emphasis on designing for Sustainability and good Urban Design principles. All our designs are given careful consideration as to appropriate construction methods, location, scale and economic expectations.

Howard Siow - Project Architect, B.Arch (MELB), M.Arch (MELB) Hons, RAIA.

After graduating from the University of Melbourne with a Masters of Architecture (1st Class Honours), in 2014 Howard started at BY Projects Architecture as an architectural graduate.

Since registering as an architect in 2017, he now manages multiple projects of varying scale independently as a project architect with the practice. With larger projects, Howard leads a team and delegates tasks and responsibilities appropriately to ensure everyone performs to their best ability, delivering the project smoothly.

Howard is passionate about creating spaces where memories will be formed. He is a strong believer that a project should be both about the end result and the whole journey of getting there. The key to a successful project is managing collaboration well across a team of clients, consultants, planners and builders.

Judit Solerdelcoll - Graduate of Architecture, M.Arch (ETSAB, UPC)

Judit is from Barcelona and graduated from Polytechnic University of Catalonia in 2018. After moving to Melbourne, she joined BY Projects Architecture in June 2021 as a Graduate of Architecture.

She is particularly interested in affordable housing, restoration, and sustainability. Judit believes that the most important aspect in architecture is the understanding of the urban and cultural context.

In Barcelona, she worked in various studios including an internship in the international architecture firm Miralles Tagliabue EMBT.

Sustainability

At BY Projects, no matter what we create, we strongly encourage all of our clients to embrace sustainable building practice. We design ecologically integrated sustainable buildings because we care about the environment, the community and built form.

We practice sustainable architecture, with an underlying philosophy of designing the built environment to comply with the fundamental principles of social, economic, and ecological sustainability. Utilising principles of passive design, we design buildings in response to climate and local conditions to be more comfortable and cost-efficient for you and your family.

“Barbara and her team of architects were recommended to us by a friend and from the moment we met, we could tell that they were a “think outside the box” group. Their interior design ideas for our kitchen and small extension were nothing at all like we had considered but met all our needs, bringing extra light and space to our home. They were prompt in answering all our questions and efficient in dealing with our builder and surveyor. In a nutshell, we couldn’t be happier.”
