Home Extensions Dulwich Hill
Built For The Way You Live
Dulwich Hill is full of federation homes and Californian bungalows on narrow blocks, typically around 12 metres wide. Most of these homes sit on 400 to 550 square metre blocks and were built between 1910 and 1940. With limited land to work with, building up or out is the only practical way to add the extra bedrooms, open plan living or home office that modern families need.
We’ve completed dozens of extensions throughout Dulwich Hill and the surrounding Inner West suburbs, working with the character of these older homes while bringing them into the 21st century. Our projects range from single storey rear additions with new living spaces to full second storey builds that double the floor area. Every job gets the same attention to detail whether it’s a small bathroom extension or a major two storey renovation.
Dulwich Hill has become increasingly popular with young families who want to stay close to the city without paying the premium for Newtown or Leichhardt. Property values have climbed steadily over the past decade, making a well planned extension a smart investment. Adding functional space means you can stay in the suburb you love rather than upsizing to somewhere further out with a longer commute.

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."
