Home Extensions Arcadia
Built For The Way You Live
Arcadia properties sit on generous acreage blocks and large residential lots, with many homes dating from the 1970s through to the 2000s. The rural character and spacious blocks make these homes perfect candidates for extension rather than moving. Whether you’re working with a brick home on five acres or a weatherboard cottage closer to Arcadia Road, there’s real opportunity to expand and modernise without losing the lifestyle that drew you here.
We’ve completed extensions throughout Arcadia and neighbouring areas like Galston, Fiddletown and Dural, where homeowners want to add space while maintaining the rural feel. Our team understands the challenges of building on sloping sites and working within bushfire prone land requirements that apply to much of the area. We coordinate all trades, manage approvals and keep your project moving from design to completion.
Families move to Arcadia for the space, privacy and semi rural lifestyle, and most plan to stay long term. Rather than selling and relocating when you need more room, extending your existing home lets you keep the property you love while gaining the extra bedrooms, living areas or studio space your family needs. With median land values continuing to climb across the Hills District, investing in a quality extension protects and increases your property value.

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 Arcadia?
Most home extensions in Arcadia take between 3 to 6 months from council approval through to final handover. The timeline depends on the scope of work, site access and whether we’re building a single storey or double storey addition. We provide a clear construction schedule before work begins so you know what to expect.
Do I need council approval for a home extension in Arcadia?
Most extensions require either a Development Application or Complying Development Certificate from The Hills Shire Council. Additional considerations apply in Arcadia due to bushfire prone land classifications and rural zoning requirements. Our team manages the full approval process including surveys, bushfire reports and all required documentation.
Can you extend homes on sloping blocks in Arcadia?
Yes, we regularly work on sloping and elevated sites throughout Arcadia. Many properties in the area have significant slope which requires careful design and engineering, but it also creates opportunities for split level extensions and walk out lower levels. We assess your site conditions early and design an extension that works with your land.

Yes we service Arcadia and all surrounding suburbs. Call 1300 098 730 to discuss your project.
