Home Extensions Kirrawee
Built For The Way You Live
Kirrawee homes were predominantly built between the 1960s and 1980s, with solid brick construction on decent sized blocks that offer genuine extension potential. Many properties sit on 550 to 700 square metre blocks, giving you room to extend out the back or add a second level without losing your yard space. The original floor plans in these homes often feature smaller living areas and dated kitchens, making an extension the smart choice over buying elsewhere in the current market.
We’ve completed extensions throughout Kirrawee and across to Gymea and Miranda, working with the area’s brick veneer and full brick homes to create modern family spaces. Our team knows the local building conditions, from the sandstone you’ll often find when excavating to the council requirements specific to Sutherland Shire. Every extension we build is designed to match your existing home while giving you the extra space your family actually needs.
With Kirrawee’s proximity to the train station, quality schools and Westfield Miranda, families want to stay in the area rather than move further out. Property prices have climbed steadily, making it more cost effective to extend your current home than to upsize in the same suburb. A well planned extension can add $200,000 to $400,000 in value while giving you the home you want in the location you already love.

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!"

We handle the entire approval process for you, working with our consulting team to get your DA or CDC through efficiently.
Can I extend a brick home in Kirrawee?
Absolutely. The majority of Kirrawee homes are brick construction, and we regularly extend these properties with additions that perfectly match the existing brickwork and roofline.

We’ve been extending brick homes across the Shire for years and know exactly how to make your addition look like it was always there.
