The Problems We Solve

Misinterpreting council regulations for FSR or lot size can kill a project early.

Designs That Don't Maximise ROI

Generic designs fail to optimise for the highest possible return on your investment.

Every week waiting for council feedback adds holding costs and stalls your return.

Get Straightforward Answers From Our Design Experts

Here are straightforward answers to the questions we hear most from investors.

What are the first steps for a duplex build?

It all starts with a simple conversation. We’ll chat about your unique vision and budget, and review your specific block of land. From there, we provide premium duplex designs offering spectacular dual living arrangements. After we lock in a clear timeline, we’ll start crafting your new facade and blueprint.

Approval times can vary depending on the local council. However, because we focus so heavily on 100% compliance from day one, we help you dodge those typical, painful delays. Our average turnaround from our first chat to approved plans is exceptionally fast. You’ll typically see results in just 4 to 6 weeks.

Absolutely. We specialise in creating intelligent layouts for challenging blocks, like sloping or narrow lots. We see these constraints as creative opportunities. Our team crafts intelligent double-storey designs that maximise your footprint and can turn that tricky block into a valuable asset.

Yes. We’ll present you with a range of dynamic designs for your build, so you’re never locked into a single restrictive idea. We bring a premium, refined feel to your custom plans, ensuring you get outstanding value. We’ll keep refining the layouts until they’re perfect and you’re completely thrilled with the final result.
