Greg Macdonald - Owner

Greg has been involved in the building industry for over 30 years and has a wide and varied expertise from multi-storied concrete structures to turn of the century Kauri villa renovations. He has gone through a traditional apprenticeship following on from his father who was also a builder for over 50 years. During most of his career, Greg has had his own building company with teams of builders carrying out new builds and renovations in the early years to a more commercial focus in recent years. He is a licenced builder a card-carrying LBP, also taken time out in his twenties to return to university and complete his Bbus, adding to that with a Postgrad dip before the building site beckoned again.

Macbuilt Steel Buildings builds sheds big and small - we have an industrial/commercial focus, but we’ll build almost anything and being builders it allows us to complete the project from start to finish. Traditional carpenters at heart we like to see the job through and can also build offices and boardrooms in your new commercial factory. Greg has an in-depth knowledge of the building industry he is involved in, “we have a lot of interaction with designers and engineers to get these buildings to look and preform right for the customer.”

Our mission at Macbuilt is simple, “The customer experience needs to be a good one”, we always want to try and adhere to that mission. With different buildings and sites almost every time, suppliers etc. this mission can be challenging to meet sometimes, but we always strive to meet that standard.

Our move into sheds, commercial and industrial buildings, rural buildings, minor dwellings etc. came in 2006. We saw a gap in the market to build these buildings well and treat the buildings and their owners with the respect they deserve. It’s been an wonderful journey for us, we have built some fantastic buildings and met some fascinating, innovative, creative, hard-working New Zealanders. Who are setting up new businesses, adding on to existing successful businesses or just building a new shed for the farm. They are all interesting, and we get a real kick out of meeting and developing relationships with our customers throughout the project. Kiwi’s are amazing, and in this job, you get to see people doing some incredible things. The biggest kick we get is these incredible people creating their dreams inside a Macbuilt Steel Building.


Building Teams

We currently run two building teams of 4 depending on the project. We have our leading hands Alex and Mike on each site running the teams. Greg has overall responsibility for each project and is on site daily for all or part of the day to assist Alex and Mike and ensure we are meeting our objectives and keeping true to our mission.

Our office is a busy one with our super star Lorraine taking care of all the essential stuff and our part time Quantity surveyor Eric, keeping everyone honest, getting costings correct and suppliers on track.
