The decision to…...design one home suitable for several generations.A multi-generational home is as much about relationships as space. We shaped the layout to give each part of the family its own privacy, while keeping a firm hold on cost, so the home met everyone's needs without overspending.
The SymphonyArchitects forSydney homesand commercial fitouts
Renovations, extensions, heritage homes, new homes and duplexes, designed and taken through council by a registered architect. Cafés, restaurants, shops, salons, clinics and offices, designed and built.
At OIC Architects, we specialise in three areas: boutique residential architecture for families, commercial fit-out design for small business owners, and building those commercial fit-outs.
Whether we're designing a family home or transforming a space for a small business, our approach goes beyond design alone.
With extensive experience in architecture, design approval management and construction supervision, we consider feasibility, planning approvals, build costs and project delivery from the beginning. Our goal is to help you make informed decisions early, protect your investment, and move confidently from concept towards construction.

Selected projects
Good projects start with good decisions.
The decision to…...design one home suitable for several generations.A multi-generational home is as much about relationships as space. We shaped the layout to give each part of the family its own privacy, while keeping a firm hold on cost, so the home met everyone's needs without overspending.
The Symphony
The decision to…...turn an awkward floor level into a feature.The tenancy came with level changes across the floor that affected access and buildability. Instead of fighting the uneven floor, we folded it into raised platform seating and let a softly lit suspended ceiling shape the room.
Sushi Train Rose Bay
The decision to…...turn one property into two homes.A tired old house in Marrickville, redesigned as two mirrored homes with the flow, natural light and open feel today's buyers look for. Approval is in progress; the images show the design.
The Duet
The decision to…...carry one brand across three different shops.Aqua Beauty Clinic's Sydney clinics in Hurstville, Burwood and Parramatta each came with a different tenancy. We kept one colour and material language, soft green, warm timber, champagne gold and curved forms, and fitted it to each site.
Aqua Beauty Clinic
The decision to…...knock down and rebuild to what the street allows.A comparable development on the same street showed what the location could support. So rather than renovate a house at the end of its life, the site is being rebuilt to that potential (it is under construction now), with a design that stands out rather than blends in.
Aurum
The decision to…...split one warehouse into two saleable units.One factory building became two separate commercial units, each with its own roller door onto a shared, landscaped forecourt, so the owner had two spaces to sell instead of one.
Food Processing FactoryHow working with us starts
No open-ended free meetings, no surprise invoices. 4 steps, and you can stop after any of them.
A free 15-minute call
Tell us about the property and what you want. We'll tell you honestly whether we're the right fit, what the approval route probably is and what the sensible next step would be.
A paid first step
For homes, a feasibility study. For businesses, an assessment before you sign the lease. Both cover planning requirements, potential issues and budget considerations, with findings provided in writing.
A written proposal
A fixed fee for each stage, what you receive at each one, how many meetings are included, and a point after the concept where you can stop.
Design, approval, build
We design, take the project through council or a certifier, document it for builders' quotes and, if you want us to, stay involved during construction.
Why people choose OIC
We Understand What You Really WantEven when you can't quite explain your vision, we know how to listen, ask the right questions and turn your ideas into a design you'll love.
Beautiful Design That Can Actually Be BuiltWe understand how buildings go together. Every design considers real construction methods, so fewer details are left for builders to figure out.
We Think Ahead, So You Don't Have ToWe consider approvals, technical requirements and construction challenges early, helping you avoid unexpected problems, delays and costly changes.
We Think Like Developers, TooWe've invested in and developed our own projects. We balance great design with realistic costs, long-term value and smart material choices through our supplier network.
Clear Communication, From Start to FinishWe listen, explain your options clearly and keep you informed. You'll understand what's happening, what decisions need to be made and why.
Extensive Experience in Commercial FitoutsFrom cafés and restaurants to shops and clinics, we understand the complex technical requirements behind commercial spaces AND how to make them look good.
"OIC considered what I'm going to do and how my family's going to use the space, not just the house itself. They asked things I hadn't even thought about, like whether I would have more kids, and they planned for it either way."

Could your project qualify for CDC instead of a DA?
Choose your project type, enter your property address and upload your Section 10.7 Planning Certificate. Our online CDC Checker reviews your property's planning information to help identify whether:
- CDC may be available for your proposed project.
- A DA may be required instead.
- Further investigation is needed due to constraints such as heritage, flooding, bushfire, etc.
Get a clearer understanding of your potential approval pathway before committing to detailed design.

Questions people ask
Do you design for homes and commercial fitouts?
Yes. Home projects (renovations, extensions, heritage homes, new homes and duplexes) and business fit-outs (cafés, restaurants, shops, salons, clinics and gyms) are run by separate people in the practice.
Where do you work?
We provide residential architecture services across Greater Sydney, with a strong focus on the Inner West (such as Leichhardt, Annandale, Lilyfield, Balmain, Tempe and Marrickville) and Lower North Shore. We've also completed projects in Wollongong. For commercial fitouts, we work with businesses across Sydney.
How much does an architect cost?
It depends on the project, so we don't quote a percentage blind. After a free 15-minute call and a paid first step, you get a written proposal with a fixed fee for each stage. Our fees page explains what each stage includes and what the whole project typically costs in Sydney.
Do you build?
Commercial fit-outs, yes: our fit-out construction team builds cafés, restaurants, shops, salons, clinics, gyms and offices, to our drawings or yours. Homes, no. For a home we design, prepare and manage the approval, and document the project so licensed home builders can quote on the same drawings. You sign the building contract with the builder you choose, and we can stay involved during construction if you want us to.
Do I need a DA or a CDC?
It depends on the property and the project. A CDC is the faster route when a project meets the state's standard rules; a DA is assessed by council and suits anything outside them, including many heritage projects. Our CDC or DA guide walks through it, and our online CDC check is coming soon.
Do you speak Mandarin?
Yes. We work in English, Mandarin, and German and you can choose the language for the first call when you book.
