Home Extensions Lapstone
Built For The Way You Live
Lapstone sits at the base of the Blue Mountains with homes mainly from the 1960s through to the 1990s built on decent sized blocks, many between 600 and 900 square metres. These older homes often have solid bones but outdated layouts, making them perfect candidates for extensions rather than demolition. The sloping terrain means many properties can take advantage of underfloor space or a second storey addition without compromising the existing footprint.
We’ve completed extensions throughout Lapstone and neighbouring suburbs like Glenbrook and Blaxland, working with the unique characteristics of mountain fringe properties. Many of our projects involve converting garages, adding second storeys to capture valley views, or extending rear living areas to connect with established gardens. Our team understands local soil conditions, bushfire regulations, and the approval process with Blue Mountains City Council.
Lapstone attracts families looking for space and a quieter lifestyle within reach of Penrith and the M4 corridor. Properties here offer good value compared to lower mountains suburbs, and a well designed extension can significantly increase your home’s worth while avoiding the cost and disruption of selling and moving. With the area becoming increasingly popular, investing in your existing home makes solid 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."

FAQS
Got a question?
How much does a home extension cost in Lapstone?
A single room addition typically starts from around $80,000, while a full ground floor extension begins from $150,000 depending on size and finishes. Second storey additions generally start from $250,000 due to structural requirements and site access considerations. We provide a detailed free quote after assessing your property and discussing your specific needs.
How long does a home extension take in Lapstone?
Most home extensions take between three to six months from DA approval through to final handover, though this varies based on the scope of work. Second storey additions or complex builds on sloping sites may take longer. We provide a clear timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Lapstone?
Most extensions in Lapstone require either a Development Application or Complying Development Certificate through Blue Mountains City Council. The area has specific requirements around bushfire protection and heritage considerations in some streets. We manage the entire approval process for you, working with certifiers and council to get your extension approved.
Can you build extensions on sloping Lapstone blocks?
Absolutely. Many Lapstone properties sit on sloping land, and we have extensive experience building extensions that work with the terrain rather than against it. We often design split level additions or use the slope to create undercroft storage or extra living space. Our engineering team ensures all structural requirements are met for hillside construction.
