Home Extensions Yanderra
Built For The Way You Live
Yanderra’s housing stock runs from older weatherboard and fibro cottages through to brick homes built from the 1970s onwards, sitting on generous rural and semi rural blocks. Many of these homes were built as simple three bedroom layouts that no longer work for modern family life. With land values staying affordable compared to metro Sydney, extending your existing home makes excellent financial sense rather than buying bigger elsewhere.
We’ve completed extensions across Yanderra and throughout the Wollondilly region, from single storey rear additions to complete second storey builds on older homes. Our team knows the local building requirements and works with the terrain that’s common to this area. Whether you need more living space, extra bedrooms, or a proper home office, we build to suit your block and your budget.
Families are choosing Yanderra for the space and community feel, often moving from tighter suburbs closer to the city. Adding a quality extension means you get the extra room you need without losing what drew you here in the first place. A well planned extension can add $100,000 or more to your property value while giving you a home that actually works for your family.

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 Yanderra?
A single room addition 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 access and existing structure. We provide a free quote and fixed price contract so you know exactly what you’re paying before work begins.
How long does a home extension take in Yanderra?
Most home extensions take between 3 to 6 months from council approval through to final handover. The timeline depends on the size and complexity of your project, weather conditions, and how quickly materials arrive. We’ll give you a realistic timeline during the quote process and keep you updated throughout the build.
Do I need council approval for a home extension in Yanderra?
Most extensions require either a Development Application or Complying Development Certificate through Wollondilly Shire Council. Some smaller projects may qualify for exempt development, but this is rare for proper extensions. Our team manages the full approval process including plans, engineering, and all submissions to council.
Can you extend older weatherboard homes in Yanderra?
Absolutely. Many of Yanderra’s older weatherboard and fibro homes are perfect candidates for extensions once we assess the existing structure. We often need to upgrade some foundation work or reframe sections to meet current standards, but these homes extend beautifully. The key is getting the design right so the new work complements what’s already there.
