Home Extensions Blakehurst
Built For The Way You Live
Blakehurst is packed with solid brick homes from the 1960s and 70s, mostly sitting on decent sized blocks between 550 and 700 square metres. These homes were built for a different era, with smaller living areas and dated floor plans that don’t suit how families live today. An extension lets you keep your established location and street while creating the extra space your family actually needs.
We’ve completed dozens of extensions across Blakehurst and surrounding suburbs like Carss Park and Kyle Bay, working with the area’s typical brick construction and understanding local council requirements. Our team knows how to work with the sloping blocks common around here, particularly those heading down towards Carss Bush Park. We handle everything in house, from architectural design through to the final coat of paint.
Blakehurst offers that rare combination of waterside location, good schools and genuine community feel that’s hard to find anywhere else in Sydney. Property prices have climbed steadily over the past decade, making it far more cost effective to extend your current home than to buy something bigger in the same area. A well designed extension can add $200,000 or more to your property value while giving you the home you want without the hassle of moving.

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!"

How long does a home extension take in Blakehurst?
Most home extensions in Blakehurst take between 3 to 6 months from DA approval through to final handover, depending on the size and complexity of your project. Council approval through Georges River Council typically adds 8 to 12 weeks before construction starts. We provide a detailed timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Blakehurst?
Most home extensions require either a Development Application or Complying Development Certificate through Georges River Council. Some smaller alterations may qualify as exempt development, but this depends on your specific site and plans. We manage the entire approval process for you, including all architectural drawings, engineering reports and council submissions.
Can you extend on sloping blocks near the park?
Absolutely. Many Blakehurst homes sit on sloping blocks, particularly those near Carss Bush Park and heading towards the water. We regularly work with these sites, using appropriate footings and design solutions that work with the slope rather than against it. Our engineers assess every site individually to ensure your extension is built properly and safely.
