Home Extensions Rockdale
Built For The Way You Live

Rockdale is packed with solid brick homes from the 1950s through to the 1980s, sitting on decent sized blocks that give you real options for extending. Many properties here have garages or rear yards that are crying out for better use, and with land values what they are, building up or out makes far more sense than moving. The housing stock is built to last, which means you’ve got good bones to work with when planning an addition.

We’ve completed extensions across Rockdale and the surrounding suburbs, working with everything from post war cottages to brick veneers that need extra space for growing families. Our team knows the local council requirements inside out, and we’ve built second storeys, rear additions and ground floor expansions throughout the St George area. Each project is different, but the goal is always the same: more space that works for how you actually live.

Rockdale families are staying put rather than trading up, which makes sense given the location between the airport and the city. Property prices have climbed steadily here, and a well planned extension can add serious value while giving you the extra bedroom, living space or home office you need right now. With Rockdale Plaza nearby and good schools in the area, it’s a suburb where people want to stay long term.

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 Rockdale?

Council approval times can vary, but once we’re on site, we keep the project moving efficiently. We’ll give you a clear timeline once we’ve worked through the design and approval stages.

Do I need council approval for a home extension in Rockdale?

Most extensions in Rockdale require either a Development Application or Complying Development Certificate through Bayside Council. The requirements depend on the size and type of extension you’re planning. We manage the full approval process for you, including all plans, documentation and council liaison.

Can I add a second storey to my Rockdale home?

Most brick homes in Rockdale have solid foundations that can support a second storey addition, but we always do a structural assessment first. Adding a second level is often the best way to gain space without losing your backyard. We’ve completed many double storey extensions across Rockdale and know what works with the local housing stock.
