Custom Home Design
New Homes
We design custom new homes across Sydney, from luxury residences to more modest builds, including acreage properties and knockdown rebuilds.
As an accredited building designer, we provide complete building design and architectural drafting services, tailored to your lifestyle, budget and site conditions.
All designs are developed with council compliance, buildability and long-term value in mind.
DA & CDC Approval Specialists
We offer creative building design, expert architectural drafting and essential supporting documentation required for DA applications, CDC fast-tracking, and Construction Certificates (CC).
Our precision ensures your project moves smoothly from the drawing board to the construction site. We manage the technical details so you don't have to.
Expert Management of the NSW Planning Portal
Navigating the NSW Planning Portal can be a major hurdle for any home project. We take the technical stress off your hands by managing the entire digital lodgement process, from initial site reports and zoning checks to final council approval.
Whether you need a Development Application (DA) or a Complying Development Certificate (CDC), we ensure your documentation is 100% compliant to prevent costly delays and rejections.
We provide building design, architectural drafting and planning support for dual occupancy, townhouse and small-scale residential developments.
Our focus is on maximising site potential while meeting council planning controls, zoning and compliance requirements.
From concept design through to DA or CDC documentation, we deliver clear, buildable plans suited to developers, investors and homeowners.
Sustainable & Bushfire-Responsive Design
With a degree in sustainable design, we incorporate passive solar principles, energy efficiency and site-responsive planning into all projects.
We also have extensive experience in bushfire-prone areas, including BAL-40 and Flame Zone design requirements.
Our approach ensures homes are not only compliant, but more comfortable, efficient and suited to their environment.
