Home Extensions Como
Built For The Way You Live

Como features predominantly brick homes from the 1960s and 70s built on generous blocks, many with original footprints that no longer suit modern family life. These solid homes sit on decent sized parcels of land, often 550 to 700 square metres, which makes them ideal candidates for ground floor or upper level extensions. With the Georges River location and established tree lined streets, homeowners choose to extend rather than sell and start again elsewhere.

We’ve completed numerous extension projects throughout Como and neighbouring suburbs like Oyster Bay and Jannali, working with the typical brick and tile homes common to the area. Our team understands the local building characteristics and council requirements specific to Sutherland Shire, which means smoother approvals and builds that respect the existing structure. Whether it’s opening up the back of the house to capture water glimpses or adding a second storey, we design extensions that work with what’s already there.

Como’s waterfront position and proximity to quality schools makes it a tightly held suburb where families want to stay long term. The local property market rewards well executed renovations and extensions, particularly those that add functional living space or extra bedrooms. A properly designed extension not only gives you the space your family needs today but significantly increases your property value in a suburb where good homes rarely come on the market.

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 Como?

Most home extensions in Como take between 3 to 6 months from development approval through to final handover. The timeline depends on the scope of your project, with ground floor extensions typically faster than second storey additions. We provide a clear schedule at the start and keep you informed throughout the entire build.

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

Most extensions in Como require either a Development Application or Complying Development Certificate through Sutherland Shire Council. The approval pathway depends on your extension size, setbacks and site specifics. We manage the entire approval process for you, including all drawings, documentation and council liaison.

Can I build up on an older Como home?

Yes, many 60s and 70s brick homes in Como have solid foundations suitable for a second storey addition. We conduct a structural assessment of your existing home first to determine what’s required, which might include some foundation strengthening. Most Como homes are excellent candidates for adding an upper level with proper engineering.
