Home Extensions Mount Riverview
Built For The Way You Live
Mount Riverview homes are predominantly brick and fibro builds from the 1970s and 1980s, sitting on generous blocks that often back onto bushland or offer mountain views. Many of these original layouts feel dated and cramped, with small living areas and limited connection to outdoor spaces. An extension is the smartest way to modernise your home while keeping the character and location you already love.
We’ve completed extensions across Mount Riverview and throughout the lower and mid Mountains, from single storey rear additions to full two storey builds. Our team understands the local building requirements, sloping sites and the importance of designing around established trees and bushland settings. Every project is managed by our licensed builders who live and work in the area.
Mount Riverview attracts families who want space, privacy and a strong sense of community without giving up access to Sydney. Property values have climbed steadily as more buyers discover the area, and a well designed extension can add serious equity while giving you the extra room your family needs. Instead of selling and starting over, most homeowners find extending their current home makes far better financial sense.

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."

Can you extend on sloping blocks in Mount Riverview?
