Home Extensions Asquith
Built For The Way You Live
Asquith is dominated by brick homes from the 1960s and 1970s, most sitting on generous blocks of 600 to 800 square metres. These solid family homes were built for a different era, and many now need more space for growing families or modern open plan living. With land in the Upper North Shore at a premium, extending your existing home makes far more sense than selling and moving.
We’ve completed dozens of extensions throughout Asquith and the surrounding Upper North Shore suburbs over the years. Most of our work involves opening up the rear of brick homes to create larger living areas that connect to north facing backyards, or adding second storeys to capture views and create extra bedrooms. Every project is different, but the goal is always the same: more space that works for how families actually live.
Asquith offers excellent schools, easy access to Hornsby Westfield, and the train station gets you to the city in 40 minutes. Properties here hold their value well, and a quality extension can add $200,000 to $400,000 to your home’s worth while giving you the space you need. For families who want to stay in the area but need more room, extending is often the smartest financial decision you can make.

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!"

FAQS
Got a question?
How much does a home extension cost in Asquith?
A single room addition typically starts from $80,000, while a full ground floor extension starts from $150,000. Second storey additions generally begin around $250,000 depending on size and finishes. We provide a detailed, obligation free quote after assessing your property and understanding exactly what you need.
How long does a home extension take in Asquith?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the scope of work. Single storey rear extensions are generally quicker, while second storey additions take longer due to structural requirements. We give you a clear timeline upfront and keep you informed throughout the entire build.
Do I need council approval for a home extension in Asquith?
Most extensions in Asquith require either a Development Application or Complying Development Certificate from Hornsby Council. Some smaller projects may qualify as exempt development, but this is rare for extensions. Our team manages the entire approval process for you, including all documentation, plans and council liaison.
Can you extend older brick homes in Asquith?
Absolutely. The majority of homes in Asquith are solid 1960s and 1970s brick construction, which are ideal for extensions. We regularly work with these homes, whether adding to the rear, building up, or reconfiguring the internal layout. The existing structure is usually in good condition and provides a strong base for quality extension work.
