From Plan to Keys: The Step-by-Step Process of Building a Duplex with Casaview Homes

Building a duplex in Sydney may sound complex, but with Casaview Homes, you’ll be supported at every stage. Whether you’re developing an investment property or creating a multi-generational living setup, our proven process ensures a seamless experience from start to finish.

Your Duplex Build Journey with Casaview Homes:

1. Site Assessment & Initial Consultation
We begin with an initial site assessment to evaluate your land, understand your goals, and assess zoning and development potential for a duplex. We also explore options like mirror-image layouts or asymmetrical designs to suit unique block shapes.
2. We offer Standard and Custom Design with Transparent Quotation
Our in-house architects will work closely with you to help you select a standard design or tailor a duplex layout that suits your lifestyle and the specific characteristics of your block. You’ll receive a detailed, site-specific quotation that covers all aspects of the build, from structural components to luxury finishes.
3. Council Approvals & Full Documentation
We prepare and submit all required documentation, including architectural plans, engineering drawings, BASIX/NatHERS reports, and development applications. Our team liaises with your local council to ensure timely approvals and resolve any compliance issues.
4. Interior Selections & Styling
Visit our colour studio to select your tiles, cabinetry, kitchen finishes, and interior palettes. You’ll be guided by experienced design consultants, with additional meetings organised with our preferred kitchen and tile suppliers. We aim to blend function, style, and value in every choice.
5. Construction & Supervision
Your new duplex is constructed under the supervision of a dedicated site manager. You’ll be invited for a formal inspection before wall sheeting and can request additional site meetings at any stage. We maintain open communication to keep you updated from the slab to the roofline.
6. Final Handover & Quality Assurance
When construction is complete, we’ll walk you through your new home at the final handover. You’ll receive a full handover pack, including warranties and certifications. Casaview Homes also provides a three-month defect liability period to ensure complete satisfaction.

Additional Post-Build Support

We stand behind every home we build. Our commitment to aftercare includes responsive communication, advice on property maintenance, and a clear process for addressing minor adjustments during the post-handover phase.
From concept to completion, Casaview Homes is your trusted partner in building quality duplex homes across Sydney—delivering design excellence, honest guidance, and real value for money.
