Home Extensions Dolans Bay
Built For The Way You Live
Dolans Bay features predominantly brick and weatherboard homes from the 1960s through to the 1980s, sitting on generous waterside blocks that back onto the bay or Port Hacking. These original homes were built with modest footprints and basic floor plans that no longer suit modern family life. With land this close to the water impossible to replicate, extending your existing home makes far more sense than selling and moving.
We’ve completed extensions throughout Dolans Bay and neighbouring suburbs like Lilli Pilli and Bonnet Bay, working with the sloping blocks and environmental considerations common to this waterfront pocket. Our team understands the local building constraints, from bushfire ratings to council requirements specific to the Port Hacking foreshore. Every project is managed by our licensed builders who live and work across the Sutherland Shire.
Dolans Bay homeowners value the quiet, private lifestyle and direct water access this small community offers. Property in this tightly held area rarely comes on the market, and when it does, buyers pay a premium for the location. A well designed extension not only gives your family the space you need but significantly increases your home’s value in one of the Shire’s most desirable waterfront locations.

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."
Amanda
"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!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. From drawings to completion it was a breeze working with them. They were easy to work with and extremely efficient and professional. Thank you for all the hard work and effort, I will recommend you to everyone I know."

We provide a clear schedule during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Dolans Bay?
Yes, most extensions in Dolans Bay require either a Development Application or Complying Development Certificate from Sutherland Shire Council. Properties near the waterfront often have additional environmental and foreshore building requirements. Our team manages the full approval process on your behalf, working with certifiers and council to get your extension approved.
Can I add a second storey to capture views?
Many Dolans Bay homes can support a second storey addition to take advantage of water views over Port Hacking. We assess your existing structure, review council height limits, and design an upper level that maximises views while meeting all structural and environmental requirements. A second storey is often the best way to add significant value in this waterfront location.
