About Structured

Structured Builders was established in 2014 originally by Colin Walsh. Over the last 7 years Structured has completed a number of high end and complex residential projects. During this time Colin has built up a team with a reputation for workmanship, honestly and reliability. In 2020 Steven Langerak joined Colin as a Director of Structured, having worked with them as a client on several projects Steven was excited to bring his commercial finance, HR and sales experience to the business. As a team we are hoping to become one of the most trusted and sought after residential building specialists in Auckland. 

Colin Walsh - Managing Director



Born in Luton, England but now a fully fledged Kiwi, Colin is a Licensed Building Practitioner with 20 years experience in the construction industry. Colin began his building apprenticeship back in the early 2000's which saw him working on a host of architecturally designed homes all over Auckland. 

Having qualified as a BCITO Builder Colin's career took him to London where he gained extensive experience as a Project Manager with London based 4C Developments. Colin oversaw several large scale building projects including Central London basement dig outs and the redevelopment of a North London Church into a stunning family home, not to mention a celebrity refurbishment or two. 

Having worked on a vast range of projects Colin is always happy to put forward ideas and suggestions to help bring your plans to life. Colin is focused on the delivery of our projects and managing our operation. 

Steven Langerak - Commerical Manager



Steven has a BCOM with a double major in Accounting and Commercial Law from the University of Auckland. Soon after the completion of his degree he found his way into Executive Recruitment & HR. After 4 years working with a large multinational recruitment business Steven had the opportunity to join a colleague and decided to start their own recruitment business in 2008. The next 12 years were an amazing ride; from just the two partners working out of home they grew to a staff of over 60 people with multiple office and became one of the largest white collar recruitment firms in New Zealand.

In 2019 Steven and the other shareholders sold the business to a private fund and he departed the business after a handover period. During this time Steven developed skills in finance, systems, HR, leadership and generally running a business through growth - all skills that Steven is excited to bring to the Structured team. Steven is focused on ensuring our systems both operational and financial support our team which allow us to deliver amazing projects and client experiences. 


"Colin and Structured Builders took on our large project in Pt Chevalier. This large renovation and extension project had many challenges with both the site and the design. Colin managed the entire project including procurement of materials, management of the subs, building work and council requirements. Our experience with Colin couldn't have been better and the finished product was exceptional."

Steve, Pt Chevalier

"Colin has been an outstanding builder on our renovation project. The job became a beast as we decided to extend and improve the home that was in a poor condition but a great location for us. Colin has brought the best of himself to site everyday over the past year, both in work and fantastic sunny attitude, adding to the process and finished outcome. We have no hesitation in saying that Structured should be your first choice in a professional builder."


Roanne, Freemans Bay

"We couldn't be happier with what Colin has created for us. Our project wasn't exactly straightforward, we particularly wanted our extension in keeping with our original home and Colin absolutely achieved this. Colin had some fantastic ideas around layout and design. A joy to work with and wouldn't hesitate to recommend."


Adrienne, Sandringham

"Colin was absolutely delightful to work with. He kept the process really simple, kept to deadline and worked within my budget. Highly recommend."
