Customise This Duplex House Plan
Would you like to change the room sizes, move internal walls, modify the kitchens or bathrooms, or adjust the exterior appearance?
At Australian Floor Plans, we can help you modify the Mark 11 Duplex Design to better suit your site, budget and lifestyle.
Simply send us your requirements, sketches or marked-up floor plan, and we can provide a quotation for the changes.
Upgrade to Full Construction Plans
When you're ready to progress beyond the concept stage, ask us about upgrading to a more detailed construction drawing package.
Depending on the agreed scope, additional documentation may include building sections, construction notes, bracing and tie-down information, and further building details.
Site-specific engineering, approvals, energy assessments, surveys and local professional certification may be required separately.
Important – Concept Plans, Not Permit-Ready Drawings
This product is a Premium Concept House Plan package, not a complete set of approved construction drawings.
The plans are intended for preliminary planning, builder pricing, design discussions and further development. Before construction, the design must be checked and adapted for the building site, local regulations, engineering requirements and relevant approvals.
Why Choose Australian Floor Plans?
We offer affordable house designs backed by more than 50 years of residential building and construction industry experience.
Our aim is to help you explore suitable designs, discuss building costs and make informed decisions before committing to expensive detailed documentation.
