Renovations to existing dwellings is the bulk part of our contracts and a market we strive in.

We like to work closely with our clients to understand their vision and their idea of a final product, then our goal is to implement it and bring that vision to reality. Everything from re-clads, new joinery, kitchen and bathroom makeovers all the way up to major re-fits, re-roofing etc

We would love to hear from you and what ideas you have for renovations  and how we can help.



Get in touch if you're looking to extend your home and add that extra master ensuite, go up another level to capture that Seaview or add an extra self contained unit! We work with recognised architects that are well established on Waiheke Island, together we can make your dream a reality. 


Shipping Container Conversions

We have done multiple shipping container conversions for clients that want a stand-alone, minor dwelling on their property for visitor accommodation, or a stylish, private office/work space. 

We also have experience in building tiny homes both on trailers and on solid pile foundations of various specs and sizes. 

Please don't hesitate to contact us for some advice, and a free no-obligation estimate.

With high end carpentry being our main business, we also like to change it up every once in a while and provide a top quality, efficient and professional concrete service, to a very high standard.

We have great credentials and testimonials around our concrete work, whether you're looking for a new exposed aggregate concrete driveway, pathways, platforms or anything concrete related, we can help!

Outdoor Construction

Back in early 2019, I got approached by a project manager to undergo a unique job, something a bit different to our normal business.

We reclaimed most of the old Matiatia wharf timber when it was under construction, and created a 100m2 outdoor communal co-working space on a private property in Onetangi. Working with Jarrah hardwood and rusticated pine.

We enjoyed this project so much, that we have decided to offer outdoor construction as a service within Coast Built.

COAST BUILT is a high end, architectural building company based on Waiheke Island.

Being a long time local Waiheke resident for over 25 years, and with a strong presence in the Waiheke trades industry for the last 12 years, we can provide not only top quality workmanship, professional client focussed manner and job efficiency, but we also bring with us all of our well established, quality sub-trades network that we have built up over years of business relationship, which sometimes can be a big challenge if you're not established in the local construction market.

We cater to all aspects of residential and light commercial construction and have experience in all types of building materials, project specifications and scope of works.

From commercial shop fitouts, to large, bespoke $10m+ architectural builds.

One of the point of differences at Coast Built, is that we like to work closely with our clients, and really dig deep in the planning stages to better understand their expectations and roles and responsibilities for the project, great communication is the key to a successful project. We also take this time to discuss with our clients any additional ideas they have for the project and how we can incorporate these ideas into the finished product.
