Home Extensions

HY’s were recommended to us after our builders went into liquidation. They were so focused on finishing our house and getting us back in. My only wish they could have been with us from the beginning!”

— Maureen Bell



A home extension, done professionally with proper planning and consideration, can be life changing for a family and add massive value to your home by appealing to a wider buyer’s market.

Deciding to add an extension to your house is a pretty big deal, and one that will be undertaken by most people once, maybe twice, for the duration of your stay in any one house.  

Whether it’s a bigger kitchen you require, or that all-important extra bedroom and bathroom, deciding to extend is an exciting and unforgettable process from start to finish, and one that the team at HY’s has gone through with families around NSW hundreds of times.

Needless to say, our understanding of extending and renovating has been greatly refined and our skills honed, to be able to deliver a finished product perfect for you. 

Hear about Alex's experience whose living room we recently extended in Woolloomooloo...

"We hired HY's to extend our living room, to completely re-do our backyard, and create a seamless indoor / outdoor experience. I have to say that the result exceeds our expectations.

I would definitely recommend HY's, they're a quality outfit, and I give them a lot of credit for in particular three things:

1) They were very open to ideas and excellent at structuring everything I threw at them into an overall plan and then project managing that plan from start to finish.

2) During the execution a few extra opportunities for improvement popped up and HY's brought them to us pro-actively. They're really good at thinking about the project from the owners perspective and don't mind being flexible.

3) Their work is top quality. It's hard to find good builders in Australia. HY's did quality work from start to finish that gives me confidence that it will last for many years. If you're looking for a competitive, top quality, boutique builder then I can definitely recommend this one." Alex Spurzem, October 2014

  • What to look for when getting a quote

    It’s important to know what to look for as you may get some estimates which seem comparatively less than others.

    Take a closer look and there can be things missing, meaning you’ll get a nasty surprise as the costs mount up.

    That won’t happen with HY’s.

    We quote for everything... that means the demolition, plumbing, electrical, splashbacks... It is priced to complete.

    HY’s provide you with talented carpenters, painters, tilers, plumbers and electricians – all without having to shop around yourself.

    And remember, we’re a small builder, so we can turn things around quickly and professionally yet make it an enjoyable process with a friendly, approachable team.

    We’ll get back to you with an estimate and timeline within 48 hours

  • Plan your budget & goals carefully.

    It’s so easy to overspend or rush into jobs which will cost you further down the track. Generally it’s a good idea to factor in an extra 10% contingency budget. And think about what is worth paying a little bit more for now which can help to reduce bills and make things more comfortable while you are living there.

    We’ll guide you

    The beauty of using HY’s is that we have the best renovation specialists to hand and take the hassle out of all the different options and decision-making, because we help guide you.

    The first thing we do is to book a consultation with you, so that you can describe the vision you have for your renovation.

    Planning and design

    At your consultation, we’ll review and measure up the space and discuss design options such as layout, cabinetry, flooring, lighting, plumbing, fittings and finishes.

    From here we guide you as to the best solution for your property’s structure, your lifestyle and your budget.
