Duplex

A duplex isn’t just two homes on a block — it doubles your opportunity - live in one, sell the other, or rent both. We handle everything from planning to completion, maximizing returns while reducing risk.

Strategy First. Every Time.

Before we lift a pen or lodge a DA, we run the numbers. That means site-specific feasibility, market testing, and zoning analysis. That way, your duplex stacks up financially even before it is built."
"We build backwards from the return — not just forward from a floorplan."

True Fixed Pricing

No lowball quotes or nasty surprises. We run competitive builder tenders to secure fixed-price contracts that protect your bottom line and peace of mind.
"If the numbers don’t work, the project doesn’t happen. It’s that simple."

Smarter Designs that Sell (or Rent)

Designs that work for the specific market are crucial. Our in-house design team creates layouts that elevate livability and resale value. More light, more space, more return.
“Smart design isn’t a luxury. It’s how you win the market.”

Smarter Designs That Sell (or Lease) Fast

Two homes means two chances to impress — and we don’t waste either. Our in-house team designs floorplans buyers love, tenants queue for, and valuers reward.
“Smart design turns space into value.”

From Concept to Turnkey — Fully Managed.

You don’t need to babysit the builder. We manage everything: demolition, approvals, design coordination, builder tenders, and handover. One team, one plan, full accountability — so you can stay focused on the big picture.
“We don’t hand you off — we handle it all.”
Not just a team. A partner in profit.

How it works

Built Like a Developer Would

We don’t do guesswork. Every Duplex project follows a proven roadmap — from feasibility through to handover — led by experts who’ve done it all before.

Step 1

Strategic Site Review

Before we draw a single line, we pressure test the strategy. That means deep market research, zoning analysis, feasibility modelling, and ROI projections to confirm a Duplex is the smartest move — not just the default one.

Step 2

Design That Drives Results

We don’t design for vanity — we design for value. Every floorplan, facade, and feature is driven by what the market wants and what your site can support. Data-led decisions, not guesswork.

Step 3

Approvals on Autopilot

No chasing consultants. No red tape delays. We coordinate DA or CDC approvals fast, using our systems and experience to keep your project moving.

Step 4

Full-Scope Construction Oversight

We manage the entire build — including builder negotiations, site prep, and quality control. Regular inspections, clear reporting, and tight risk management mean no corners are cut and no nasty surprises.

Step 5

Sell or Hold — Either Way, You Win

Once complete, we don’t disappear. Whether your goal is to sell for profit or hold for income, we bring it home — so the final move is just as strategic as the first.

I’ve been in finance for over a decade, helping thousands of clients build wealth, but when it came to doing a development for myself I knew I needed the right partner. I had spent years and a lot of money on courses, but real life is different from theory - and that’s where OIC stood out, turning knowledge into real results. Clovia’s expertise goes far beyond design: she understands finance, feasibility, timelines, cost control, and she knows how to navigate every challenge. What I respect most is the integrity - OIC isn’t just building to sell, they are creating homes with long term value for families, which is exactly how I see wealth in finance. For me, working with OIC is more than a service, it’s a partnership - and this project we’re doing together is proof of what’s possible when design, finance and strategy all come together.

We came in with a million ideas for our dream house. Clovia took all of that, really listened to us and turned it into a design that was smart, beautiful and exactly what we wanted. When we saw the 3D renders - the facade, the skylights, the way the spaces flowed - we knew that this is it. Working with her was so easy - she handled everything and we felt in such good hands.

I am a buyer’s agent, but when it came to property development I knew I needed a team I could trust. With Clovia and OIC handling everything, I barely had to lift a finger and it felt just as smooth as the service I try to give my own clients. I had tried courses and even worked with other teams before, but the results were poor. With OIC, the value far outweighs the cost. Their pricing isn’t the cheapest, but you see why — they actually care about quality and create homes people truly want to live in, not quick, low-grade stock. For me, that long-term mindset is what matters most and it’s why I tell anyone starting their first development or building their dream home: find a professional team you can trust. For me, that’s OIC.

Most people think design isn’t worth spending on, but as a builder I know that good design saves money later. With OIC, the drawings are clear and thought through at the start, so the build runs smoothly and there is less wasted time and cost fixing problems. Clovia can be picky on site - but in a good way, because it means fewer mistakes and less risk for me as a builder. She also strikes the right balance between design and budget, choosing materials and details that deliver maximum effect without overspending. To me, that is real value! My advice to anyone building a home is simple: listen to professionals like OIC - it will save you time, money and stress.
