Improve Your Home by Building Modern Home Extensions in Perth

We go out of our way to make our Perth home extensions stress-free. As a homeowner, there’ll always be a time when an upgrade is the best solution for your changing needs. Rather than going through the stressful, drawn-out process of selling your current home and purchasing another, many Perth homeowners are turning to home extensions as a more affordable and simpler option.

Home extensions are a great way to get the features you want without blowing your budget. We know how disorienting the process can be, so we take great care to disrupt your home life as little as possible. You can even live in your home while we’re busy extending your space.

By adding more square metres to your living space, you’re also instantly and dramatically increasing the value of your home. With over 40 years of experience, Sertorio Homes has been trusted to build some of the most impressive home extensions in Perth.

We cater for both single and double-storey home extensions and build on your ideas to transform them into outstanding creations.
