FAQs
GET STARTED TODAY
Can IMSU knock down a house and rebuild?
Yes, we can.
We have extensive experience with knock down rebuilds across a wide range of sites and council areas. We understand the complexities involved and what it takes to deliver a smooth, successful outcome.
Knock down rebuilds can be challenging. Council approvals, zoning checks, site assessments and heritage restrictions can all influence what’s possible. It’s a process that requires careful planning from the outset.
Our team is here to make that process easier. With in-depth knowledge of local regulations and a proven approach to managing approvals, we make the process simple and painless.
How long does a knock down rebuild take?
At IMSU, we take the necessary time to build a home that will last and that we can all be proud of. With that in mind, it usually takes 18-24 months to go from design to completion. It doesn’t take long to knock down a house so the timeframe is the same as a build on a vacant block.
• 6-12 months to complete design, get council approval and prepare the site including demolition
• Up to 12 months for construction
There are several factors that can influence the timeframe for construction but contracting experts helps to reduce delays. Our experience enables us to predict and mitigate delays in the process and keep a consistent timeframe.
Is it cheaper to knock down and rebuild or renovate?
When renovating, you should expect unexpected costs. Your current builders are becoming more familiar with the existing structure and naturally find unpredictable problems.
At IMSU we are able to offer very consistent and predictable pricing because we know our homes well and we know Sydney. We also use modern materials, new systems, and a design tailored from the ground up for a more efficient construction process and a better home. Many homeowners are surprised to find that starting fresh can be both simpler and smarter.
Is it worth knocking down and rebuilding?
In our experience, it absolutely can be. If you love your neighbourhood but your home just doesn’t meet your needs anymore then it is a great option. A rebuild allows for:
• Increased energy efficiency
• Maximised usable space
• Additional rooms
• Improved visual appeal
• A home that feels truly personal
• All-new structure, plumbing, and electrical for better lifespan and function
• Fewer hidden costs or surprises compared to renovating an older home
These are some of the reasons that home owners often work with us to knock down and rebuild their homes. Additionally, our state-of-the-art colour studio gives you the comfort of seeing all the details of your new build before it even begins. We’ve found that this process is often a very rewarding one as it allows you a lot of flexibility, reliability and results in a home, personalised to your needs.
