Home Extensions Haymarket
Built For The Way You Live
Haymarket sits right in the city fringe with a mix of older warehouse conversions, heritage terraces and more recent apartment developments. The older terrace homes here typically sit on compact blocks, often around 100 to 150 square metres, where every bit of space counts. An extension is often the smartest move when you want to stay close to the CBD without paying inner city prices for more room.
We’ve completed extensions throughout Haymarket and neighbouring suburbs like Ultimo and Surry Hills, working within the tight site constraints that come with inner city living. Our team knows how to maximise limited space, whether that’s adding a second level or pushing out into a small courtyard. Every project gets the same careful planning to make sure the new space actually works for how you live.
Living in Haymarket means you’re within walking distance of Chinatown, Central Station and the CBD, which is why families and professionals want to stay here long term. The property market here moves fast, and adding usable square meterage through an extension can add serious value to your home. Rather than moving further out, you get the extra bedroom, home office or open plan living area you need while keeping that unbeatable location.

Don't Take Our Word For It
"I contacted Monstructions to get an idea of a price for doing an extension on my home. Of course I contacted many other people but they were the only ones who came back to me and assisted in giving me an idea of the price. I was so grateful. I wouldn't hesitate in recommending this company as we couldn't be more happy with the team, thank you for your help and support."

"We had a plan of what we wanted with our 2nd story + granny flat addition, but also had a budget to meet..the Monstructions team worked hard to make that happen for us. With a few little hiccups along the way from weather delays, the boys kept the job moving as smoothly as possible and the team were amazing in keeping mess to a minimum. Allowing us to stay at home during the reno. 100% highly recommended!"
