Strategy-Led — Always

We look at your property like a developer would. That means we ask the big questions: What’s the highest and best use of the site? What changes will actually shift the valuation? Which upgrades add value — and which just add cost?
"Most renovators build for the now. We build for the next buyer."

Smart Additions, No Money Wasted

Every alteration and addition we design is tailored to what the market wants — and what your site can sustain. We don’t just add space. We add value.
“More square metres don’t mean more return — smarter ones do.”

Faster Outcomes, Lower Risk

We handle approvals, consultants and builders so your project never stalls. Faster completion, lower costs, zero stress.
"We turn potential into performance — without blowing the budget or the timeline.”

Fully Managed — From Feasibility to Final Sign-Off

Design, approvals, tenders, builder management — we run the whole process, start to finish. No chasing trades, no guessing costs, no decision fatigue. Just one clear path from where you are to where your property needs to be.
“You focus on the why. We handle the how.”

Not just a team. A partner in profit.

How it works

Built Like a Developer Would

We don’t do guesswork. Every projct 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, regulatory analysis, feasibility modelling, and ROI projections to confirm an Alteration Addition 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 efficiently, 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.
