Home Extensions Mulgoa
Built For The Way You Live
Mulgoa homes sit on some of the most generous blocks in the Penrith area, with many properties on acreage or large residential lots built from the 1980s onwards. The area features a mix of brick and weatherboard homes, older cottages, and newer rural residential builds. With land this size, extending your existing home often makes more sense than the disruption and expense of moving, especially when you can design exactly what your family needs.
We’ve completed extensions throughout Mulgoa and nearby suburbs like Wallacia and Luddenham, working with the unique character of rural residential properties. Whether you need a second living area, extra bedrooms for a growing family, or a modern kitchen and dining space, we design extensions that work with your existing home and block. Our team understands local council requirements and manages every stage from concept through to completion.
Families move to Mulgoa for the space, privacy and semi rural lifestyle while staying close to Penrith and the motorway. Property values in the area continue to climb as more buyers seek larger blocks away from dense suburban development. A well planned extension protects your investment and creates the home you need without sacrificing the lifestyle you moved here for.

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."
