Home Extensions Hammondville
Built For The Way You Live

Hammondville homes are mostly brick and tile properties from the 1970s and 80s, sitting on decent sized blocks around 550 to 700 square metres. These solid homes are perfect candidates for extensions, with good bones and enough land to add a new living area, extra bedroom or second storey without losing precious backyard space. The original layouts often feel closed off and dated, making an extension the perfect solution to bring in more light and create the open plan living families need today.

We’ve completed extensions throughout Hammondville and right across the South West Sydney area, working with families who need more space but love their location. Our team knows the local housing stock inside out, from the typical slab on ground construction to the roof pitch and setback requirements that matter when you’re planning an addition. Every project gets handled by our licensed builders from concept drawings right through to the final coat of paint.

Hammondville offers affordable family living with good access to the M5 and local schools, which is why so many homeowners choose to extend rather than move and pay stamp duty all over again. Properties here have seen solid growth over the past decade, and a well designed extension can add significantly more value than it costs to build. Families are choosing to invest in their current home rather than upsize into a bigger mortgage, especially when they’ve already got established gardens and great neighbours.

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!"

How long does a home extension take in Hammondville?

Council approval itself can take 8 to 12 weeks depending on whether you need a DA or can use a CDC. We’ll give you a clear timeline at the quote stage so you know exactly what to expect.

Do I need council approval for a home extension in Hammondville?

Yes, most extensions in Hammondville require either a Development Application or Complying Development Certificate from Liverpool Council. The type of approval depends on your specific project, site constraints and how much floor area you’re adding. Our team manages the entire approval process for you, from preparing plans through to lodgement and dealing with any council requirements.

Can I add a second storey to my Hammondville home?

Most brick homes in Hammondville can structurally support a second storey addition, but it requires a structural engineer’s assessment of your existing footings and walls. The 1970s and 80s homes in the area were generally built with slab on ground construction, which often needs underpinning or additional structural work. We arrange all the engineering reports and handle the structural upgrades as part of your project.
