How we help you?

Certified Home Extensions provides full project management, from developing your ideas for your dream home, to finding you the right designer, then helping you through the consenting process, right through construction to your projects completion.

It is especially important to us that your home is designed and created to suit your lifestyle, fulfil your family’s needs, and fit within your budget. We will introduce you to one of our carefully chosen design companies that we are confident will help you best in all of the above requirements and more.

How we can confidently supply you with a fixed price fee proposal, even on a challenging extension or custom new home, is by providing all our sub-trades an accurate description of works, before meeting with them at your home where the work is about to commence.
We then check all their quotes to ensure nothing is missing.

You can have peace of mind that your home will be completed to the highest level, from the foundations right through to the finishing touches. During construction you home will be rigorously critiqued against our 266 point quality control checklist to ensure nothing is missed.

Certified Home Extensions are members of the New Zealand Certified Builders Association, so you can enjoy ultimate peace of mind knowing that only qualified, trained and experienced builders are attending to your project. All our work will be backed by New Zealand’s most comprehensive 10 year residential building guarantee.

Communication is the key to success, this is why Certified Home Extensions have developed comprehensive systems to keep you informed every step from design to completion. We have also invested in the most up to date scheduling technology to ensure your home will be completed on time and budget.

Barefoot Walking Guarantee

Sites so safe, you can admire progress in bare feet!

Many of our clients choose to remain in their homes throughout the course of construction, so we place a huge emphasis on keeping a tidy, safe site. This ensures that the building experience is both as enjoyable and as easy as possible for your family, and there are minimal disruptions and as little inconvenience as possible.

The construction stage of your project is the most exciting and we understand that you are going to want to come & admire progress. 

We want to ensure you are safe when we take you through a tour of the construction at your home.

Who are Certified Home Extensions?

Alvin and his lovely wife Annalise began Certified Home Extensions in 2003 after noticing a lack of trade qualified builders providing a premium experience specifically for extensions. 

To this day, there is nothing that they love more then handing over the keys to a top quality home, knowing that families will be enjoying it for years to come.


Look forward to meeting you soon and discussing how we can make your design to construction experience easy!
