Architectural Design for Homes, Multi-residential and Commerical Projects

McCullum Ashby Architects is based on Sydney’s Upper North Shore and specialises in bespoke residential homes, alterations and additions, multi-residential developments and commercial architecture. With extensive experience across the North Shore, Northern Beaches and Greater Sydney, we provide thoughtful architectural design solutions that balance creativity, planning expertise and commercial understanding.

Our work ranges from contemporary new homes and heritage renovations through to townhouse developments, seniors housing, co-living projects, mixed-use buildings and commercial fitouts. We work closely with homeowners, developers and business owners to unlock the full potential of each site while navigating the complexities of council planning controls, Housing SEPP pathways, heritage requirements and environmental constraints.

Every project begins with a strong understanding of site, context and client objectives. Whether designing a luxury residence, testing development feasibility or revitalising an existing commercial asset, our architectural approach focuses on delivering high-quality, functional and enduring outcomes that maximise value and improve the way people live and work.

Our experience includes working with complex sites involving Heritage Conservation Areas (HCA), bushfire-prone land, sloping sites, flood-affected properties and environmentally sensitive land. We regularly work with Councils, providing strategic advice from feasibility through to approvals and construction.

Established under the name of G. Gordon Fuller Associates (GGF Architects) in 1977 by the now retired Mr Gordon Fuller, Christian McCullum and Murray Ashby joined in 2001 and 2003 respectively and continue to serve the local community.  At McCullum Ashby Architects, we believe good architectural design is about more than buildings, it is about creating places that respond to people, landscape and community while delivering long-term value.

Whether you are planning a new home, multi-residential development or commercial project, we can help guide your project from concept to completion through thoughtful architectural design and experienced project leadership.
