Home Extensions Tennyson
Built For The Way You Live
Tennyson is home to a mix of older brick homes and fibro cottages from the postwar era, typically sitting on modest blocks between 400 and 600 square metres. Many of these homes were built with smaller floor plans and limited living space, which made sense decades ago but doesn’t work for modern family life. An extension is often the smartest way to gain the extra room you need without leaving a well located suburb close to transport and schools.
We’ve completed plenty of extension projects throughout Tennyson and neighbouring suburbs like Homebush and Strathfield, working with the typical housing stock in this area. Whether it’s adding a second storey to capture more space on a compact block or extending out the back for an open plan kitchen and living area, we understand what works in these older homes. Our team manages the full build from concept through to completion, including all council approvals and coordination with trades.
Tennyson’s location near good schools and transport makes it popular with families who want space to grow without moving further out. Property values in the area have climbed steadily, and a well executed extension can add significant value while giving you the home layout you actually need. Instead of selling up and paying stamp duty to move, extending your current home lets you stay in the area you know while creating the extra bedrooms, living space or home office that modern life demands.

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!"

Our team manages the entire approval process for you, including all documentation and liaison with council and certifiers.
Can you extend older fibro homes in Tennyson?
Yes, we regularly extend older fibro and brick homes throughout Tennyson and the surrounding area.
