Home Extensions Cronulla
Built For The Way You Live

Cronulla homes are mostly solid brick and fibro builds from the 1950s through to the 1980s, sitting on decent sized blocks between 550 and 700 square metres. Many original homes feature modest floorplans with small kitchens and limited living space that no longer work for modern family life. An extension makes far more sense than buying into the current Cronulla market at over $2 million for a family home.

We’ve completed dozens of extensions across Cronulla and neighbouring suburbs like Caringbah and Woolooware, from rear additions that open up living areas to full second storey builds that capture ocean breezes. Our team knows the local housing stock inside out and understands what works on these blocks. We handle everything including council approvals through Sutherland Council so you don’t have to chase architects, engineers and certifiers separately.

Cronulla’s beachside location and strong community keep property prices high, which means renovating and extending your existing home delivers serious value. Families want to stay near the beaches, schools and the village atmosphere without paying millions for a new purchase. A well designed extension can add $300,000 to $500,000 in value while giving you the home you actually want to live in.

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!"

FAQS

Got a question?

How much does a home extension cost in Cronulla?

A single room addition in Cronulla typically starts from $80,000, while a full ground floor extension starts from $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a free quote after an onsite consultation to assess your property and discuss what you want to achieve.

How long does a home extension take in Cronulla?

Most home extensions in Cronulla take between 3 to 6 months from DA approval through to final handover. The timeline depends on the scope of work, whether structural changes are needed, and weather conditions. We provide a clear construction schedule at the start so you know exactly what to expect.

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

Most extensions in Cronulla require either a Development Application or Complying Development Certificate through Sutherland Council. Some minor additions may qualify for exempt development but this is rare for proper extensions. We manage the full approval process including liaising with council, architects and certifiers on your behalf.

Can you extend upwards on older Cronulla homes?

Yes, many older Cronulla homes have solid foundations that can support a second storey addition with the right structural engineering. We assess your existing structure first and work with engineers to ensure everything is done safely and to code. Adding a second storey is often the best way to maximise your block without losing yard space.
