Woonona Custom Home Builders and Duplex Specialists
Custom homes, duplexes and knockdown rebuilds in Woonona, built by an award-winning local team
Woonona might be the busiest duplex suburb in the northern Illawarra right now, and for good reason. Wide, flat blocks in the streets between the Princes Highway and the beach, strong rental demand, and a village feel that families do not want to leave. TAG Homes has completed a luxury duplex here and the Lang Street custom home, with another duplex underway in the suburb today. We won the Medium Density Projects, Dual Occupancy category at the 2026 Master Builders NSW Southern Regions Excellence in Building Awards, so this is work we are recognised for, not work we dabble in.
Building Services in Woonona
We build custom homes, duplex and dual occupancy homes, and knockdown rebuilds across Woonona, from the older streets near the school up to the newer pockets below the escarpment. Many Woonona blocks sit in a low density residential zone where Wollongong City Council permits a dual occupancy once the lot meets minimum size and frontage requirements, and getting that assessment right before you buy or commit is where we add value early. Salt air is a real factor this close to the beach, so we specify fixings, frames and finishes to suit coastal conditions rather than treating every site the same.
Why Choose TAG Homes as Your Woonona Builder
We take on a limited number of builds at a time so the directors stay across every site, and Woonona is home turf for our trade base. You deal directly with Grant from the first phone call, you get a genuine guide price from comparable Illawarra builds before spending anything on documentation, and you sign a fixed price contract before we start. Our completed Woonona duplex and the Lang Street custom home are both in the portfolio, and the clients who own them are the kind of proof no brochure can fake.
Building with Us in Woonona
The process starts with a phone call about your block and your brief. From there you send through your plans, or start with our drafting team if you do not have plans yet. We give you a realistic guide price, and if the numbers work we produce full tender documentation for a set fee. Whether you are weighing up a renovation against a knockdown rebuild or planning a duplex to live in one side and rent the other, call Grant on 0423 409 212. It is the easiest way to get the conversation started. Building a few streets south? We work across the neighbouring beach suburbs too, including Towradgi.

Woonona Building Questions We Hear Most
Can I build a duplex on my Woonona block?
In most of Woonona's low density residential streets, Wollongong City Council permits a dual occupancy once the block meets minimum lot size and frontage requirements. Send us your address and we will tell you where your block stands before you spend anything on design.
Is it cheaper to renovate or knock down and rebuild in Woonona?
For most original Woonona homes, a renovation of any real scale costs a surprising portion of a brand new build and still leaves you with old bones. A knockdown rebuild gives you a new home, a new warranty and a design that actually suits the block.
Can I live in one side of a duplex and rent the other?
Yes, and it is one of the most common reasons our Woonona clients build one. You get a new home for your family and a rental income next door, on land you already own.
