Home Extensions Vaucluse
Built For The Way You Live
Vaucluse is home to some of Sydney’s most significant period properties, from grand Federation and Interwar estates on generous blocks to solid California Bungalows and 1960s brick homes. Many of these properties were built before open plan living became standard, and most have kitchens, bathrooms and laundries that don’t match how families live today. An extension is often the smartest way to modernise these homes while keeping the street appeal and established gardens that make Vaucluse such a beautiful place to live.
We’ve completed extensions throughout Vaucluse and neighbouring suburbs like Rose Bay and Dover Heights, working with everything from sandstone cottages to post war homes. Our team understands how to respect the original architecture while creating modern, functional living spaces that work for today’s families. Every project is managed by licensed builders who coordinate trades, approvals and timelines so you get a quality result without the stress.
With Vaucluse’s median house price well above the Sydney average, homeowners here are choosing to extend rather than upsize to another property and pay stamp duty again. Adding a second storey, extending the rear or converting unused space delivers real value in this tightly held suburb. The right extension not only improves how you live day to day but protects your investment in one of Sydney’s most desirable postcodes.

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."

FAQS
Got a question?
How much does a home extension cost in Vaucluse?

How long does a home extension take in Vaucluse?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the scope of work. A single room addition is usually quicker, while a second storey or large ground floor extension sits at the longer end. We give you a clear timeline before work starts so you know what to expect.
Do I need council approval for a home extension in Vaucluse?
Most extensions in Vaucluse require either a Development Application or Complying Development Certificate from Woollahra Council. Some smaller alterations may fall under exempt development, but this depends on the specific work and your property. We manage the full approval process including plans, documentation and submissions so you don’t have to deal with council directly.
Can you add a second storey to period homes?
Yes, we regularly add second storeys to Federation and Interwar homes throughout Vaucluse. The key is working with an engineer to assess the existing structure and designing the addition to complement the original architecture. Many period homes in the area have already been extended upwards, and done well, a second storey adds significant value without compromising the character.
