The Faces Behind Certified Home Extensions

Alvin Chisnall

Commander of Construction

Alvin is the Commander of Construction and Company Director of Certified Home Extensions. His primary responsibility is working with you from design to construction to ensure that the process remains stress free and runs as smoothly as possible.

There is nothing that he loves more and works harder for then the satisfaction of handing over a key to happy clients after another successful extension, renovation or new build has been completed.

When he isn’t on site or on the telephone speaking with clients and managing subcontractors, you can usually find him in the office compiling action plans that will show you every component that makes up your completed dream home.

Other then running around after his four adorable children Makayla, Sofia, Damien and Oakley or spending time with his lovely wife Annalise, his passion is helping you to create a home that you and your family can enjoy for decades into the future.



Alex Nguyen

Marketing & Operations Officer

Alex is a key member of the Certified Home Extensions team. He works closely with Alvin and Emily designing marketing campaigns and working on new initiatives that will allow the company to help more people such as yourself, know that we are the right builders to make the dream that you have for your home a reality.

When he isn’t developing the CHE brand to reflect the company’s family centered values, he is consistently modifying operations within the office to ensure that every person who comes into contact with our team has an unrivalled client experience.

Outside of office hours Alex enjoys spending time with his gorgeous partner Linda and beautiful daughters Ava and Violet especially when it involves walks on the beach, animated movies at the cinema and yummy meals out in flash restaurants.


Emily Higginston

Sargent of Sales

Emily is the vivacious voice behind the phone at Certified Home Extensions. Full of vim and vigor there is nothing she loves more than having a good natter with you about the dream that you have for your home and why we are best qualified to help you make it a reality.

As you proceed from design to construction Emily will support you every step of the way minimizing your stress levels and making sure you remain updated and informed about exactly what is happening with your project.

When she isn’t speaking with clients you can find her continuously working on marketing Certified Home Extensions making sure as many people as possible are aware of our superior reputation as the extension and renovation specialists. In her spare time she enjoys socializing, shopping, spending time with her loved ones including ratbag cats Dude & Bro and sitting (preferably somewhere sunny with a soppy romance).

We believe having integrity and a good attitude about everything we do on the building site impacts positively on the high standard of workmanship... which we strive to deliver on every project. Going that extra mile for you, having pride in our workmanship and enjoying a little good hearted banter and humour with you are all part of our good days work! We look forward to working with you one day soon and we’ll show you what a trustful bunch we really are!
