We believe that part of doing an excellent job is regular communication and strong client relationships.

Clarke Construction was established in Marlborough in 2007 by Ant and Sarah Clarke, and has grown to become one of the region’s leading architectural building companies.

Our solid reputation for service, reliability and excellent workmanship, has enabled us to establish strong relationships with local architects, designers and tradesmen. We use experienced sub-contractors and suppliers for all our building projects, and have a reliable, hardworking team who are forward thinking and embrace new technologies, materials and products.

We pride ourselves on our ability to develop strong relationships with our clients, and believe that regular, open communication is integral to the success of every building project.  This proven approach means that most of our work comes from repeat business or referrals. Our clients enjoy working with us and we love being part of their building journey.  

Our sister company

In August 2018, we purchased sister company Haack Construction to extend our offering and expand our capabilities. Haack Construction specialises in building and renovating commercial buildings, with the new ASB Marlborough Anderson Theatre currently under construction. Notable past projects include the Blenheim i-Site building, the Picton Emergency Operations Centre, school buildings and other Marlborough commercial projects.

Health and safety

At Clarke Construction, we operate under strict workplace safety guidelines set out in our Intesafety Health and Safety Management Plan and meet all occupational Health and Safety regulations both on and off site. We are also a member of the Registered Master Builders Association.
