Calder Stewart is proud of its family owned and operated culture, allowing it to be guided by a long term strategic vision and capable of adapting to changing construction market conditions over the years. Today co-founder Bruce Stewart's four sons, Peter, Alan, Andrew and Donald both manage and work within the business, with Peter and Alan Stewart acting as joint managing directors. Calder Stewart is also proud of its distinct relationship with the Milton community, the place we have called home for more than a half a century. Despite our success and expansion to locations nationwide, the company has resisted relocating our main headquarters away from the community in which it was founded. Our recently completed Milton-based headquarters, awarded a gold reserve medal by New Zealand's Registered Master Builders in 2010 for its environmentally responsible design, is testament to our progressive thinking as a builder whilst maintaining traditional values as a committed employer of a multi-generational skilled workforce.
