Duplex Design Specialists
Duplex developments require careful architectural planning to balance site efficiency, planning compliance, and strong residential design outcomes. At Yaz Design, we specialise in designing duplex homes that maximise the development potential of residential sites while maintaining architectural quality and buildability.
Every duplex project begins with a detailed planning review to understand zoning controls, minimum lot requirements, setbacks, floor space ratios, and other planning constraints. From there, we develop well-considered design solutions that respond to the site conditions while delivering functional and marketable homes.
Our approach focuses on creating duplex developments that are practical to construct, compliant with local planning controls, and carefully designed to achieve strong long-term value for both owner-occupiers and investors.
01.
Initial Consultation & Feasibility Review
We begin with an initial consultation to understand your objectives, site conditions, and project scope. This stage focuses on due diligence.
We review the Planning Certificate (Section 10.7), zoning controls, relevant LEP and DCP provisions, title constraints, and available site documentation to identify key planning considerations and potential limitations.
Where required, we advise on the most suitable approval pathway, including DA or CDC. The outcome of this stage is clarity — an informed understanding of what is achievable and a defined direction before formal design work begins.
02.
Proposal & Project Engagement
Following the feasibility review, we prepare a detailed fee proposal outlining the agreed scope of works, deliverables, staging, and associated costs. Once the proposal is accepted, the project is formally engaged and we proceed into structured design development.
03.
Design Development & Client Approval
The design stage commences with concept plans responding to the site constraints and project brief. Layout efficiency, built form articulation, setbacks, height controls, and compliance considerations are addressed from the outset.
Through structured review meetings, the design is refined into a resolved architectural proposal including developed floor plans, elevations, site planning, and key documentation required for submission.
04.
Documentation & Consultation Coordination
Once the architectural design is confirmed, we coordinate the required consultants and prepare the supporting documentation necessary for submission.
Depending on project requirements, this may include structural engineering, stormwater design, BASIX or energy assessment, geotechnical input, arborist reporting, town planning advice, and other specialist documentation.
All consultant information is integrated into a coordinated submission package.
05.
Approval & Certification
The final stage involves lodging the project for approval.
Where applicable, this may proceed via Development Application (DA) with Council or through a Complying Development Certificate (CDC) pathway with a private certifier.
We manage the submission process and assist through to determination, resulting in an approved set of documents ready to proceed to construction.
