Home Extensions Lawson
Built For The Way You Live

Lawson’s housing stock is largely made up of weatherboard cottages and brick homes from the 1950s through to the 1980s, sitting on generous blocks that typically range from 600 to 1000 square metres. Many of these older homes feature smaller living areas and limited bathroom facilities that no longer suit how families live today. With land this size in the Blue Mountains becoming harder to find, extending your existing home makes far more sense than trying to buy bigger in the current market.

We’ve completed extensions throughout Lawson and neighbouring Blue Mountains suburbs, working with everything from original Federation cottages to mid century brick homes. Our team understands the local building requirements and how to design additions that respect the mountain character while giving you the extra space you actually need. Whether it’s a rear living extension, extra bedrooms or a second bathroom, we build to suit the way your family lives.

Lawson attracts families and retirees who want the mountain lifestyle without paying Katoomba or Leura prices, and property values have climbed steadily over recent years. A well planned extension can add serious value while letting you stay in a location you already love, close to the station and village shops. Rather than moving and paying stamp duty plus agent fees, most homeowners find extending gives them exactly what they need at a fraction of the cost.

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!"
