Home Extensions Harris Park
Built For The Way You Live
Harris Park homes are mainly weatherboard and brick cottages from the 1920s through to 1950s, sitting on narrow blocks between 400 and 550 square metres. Many of these older homes have compact floor plans with small kitchens and limited living space, making a well planned extension the smartest way to gain the room your family needs without leaving the area. The original character and solid bones of these homes make them perfect candidates for rear or side extensions that add modern living space while keeping what you love about the place.
We’ve completed dozens of extensions throughout Harris Park and the surrounding Parramatta suburbs, working with the typical constraints of smaller blocks and heritage considerations. Our team knows how to maximise space on these tighter sites, designing additions that flow naturally from the original home while meeting all current building standards. We handle everything from single storey rear extensions through to full second storey additions, always keeping disruption to a minimum during construction.
Harris Park’s location just minutes from Parramatta CBD and the train station makes it popular with families who want space without a long commute. Adding a quality extension can easily add $150,000 to $300,000 to your property value while giving you the extra bedrooms, larger kitchen or open plan living area you actually need. Instead of moving further out and losing that convenient location, most Harris Park families find extending their current home makes far more financial sense.

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!"
