Home Extensions Mount Annan
Built For The Way You Live
Mount Annan’s housing stock is predominantly modern family homes built from the late 1990s onwards, sitting on decent sized blocks that typically range from 450 to 700 square metres. Many of these homes were built with future growth in mind but as families expand and work from home becomes more common, the original floor plans often fall short. An extension makes far more sense than uprooting to a larger home, especially given the strong community connections many families have built here.
We’ve completed extensions throughout Mount Annan and nearby suburbs like Currans Hill and Narellan Vale, working with the area’s brick veneer and rendered homes. Our projects here range from simple single room additions through to full ground floor expansions and second storey builds that take advantage of the views towards the botanical gardens. Every job is managed by our licensed team who understand local building codes and council requirements inside out.
Mount Annan attracts young families who want good schools, parks and a relaxed lifestyle without being too far from Sydney. Property values here have climbed steadily over the past decade as the area matures and infrastructure improves. Adding a well designed extension not only solves your immediate space problems but adds significant value to your property, often returning more than the build cost when it comes time to sell.

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 Mount Annan?

The timeline depends on the scope of work, weather conditions and material availability. We’ll give you a realistic schedule during the quoting process and keep you updated throughout the build.
Do I need council approval for a home extension in Mount Annan?
Most extensions in Mount Annan require either a Development Application or Complying Development Certificate from Camden Council. The approval pathway depends on your property, the size of the extension and setback requirements. Our team manages the full approval process including architectural plans, engineering and all council submissions so you don’t have to worry about the paperwork.
Can I add a second storey to my Mount Annan home?
Yes, many Mount Annan homes are ideal candidates for second storey additions given their solid brick construction and concrete slab foundations. We assess the existing structure to ensure it can support the additional load, and design the upper level to complement your home’s existing style. Second storey builds are popular here because they maximise your land without losing backyard space.
