We design and build award-winning custom homes

About GN Williams

We build high-quality new homes in the Illawarra and NSW South Coast, with a fully custom design and build service that will keep you front-and-centre every step of the way.

Integrity and experience

The GN Williams team enjoys the highest levels of respect in the industry, from peak bodies to local tradespeople. Our three Directors (who will all be hands-on in your build) have over 60 years’ combined experience. That’s a lot of expertise to help you make your custom dream home a reality.

Local knowledge

We’ve been building custom homes in the Illawarra and South Coast regions since 1996, under our GN Williams name and also our umbrella company South Coast Homes. We know how to build for local conditions and make the best of our beautiful region.

One company. Three builders. And they’re all yours.

When you build with GN Williams, your new home will be built by our three Licensed Builders: Brad Williams, Matthew Anderson and Jimmy Brennan. They’re professionals who treat every GN Williams build like it’s their own, and so they should. After all, they own the company.

When you pick up the phone or visit on site to chat to your builder, you’ll talk to someone who knows that the good reputation of GN Williams rests on the quality of their work and your customer experience. Here’s how our trio work:
