About Grant

For the past 30 years, Grant has been building landmarks all over Marlborough. While most of his work in recent years has been as a site manager running large commercial jobs, there have been some very interesting, high-end residential builds as well. With all this experience, Grant has a keen eye for detail and a sharp mind for problem-solving. As a Licensed Building Practitioner and with his extensive knowledge and understanding of building practices and construction methods, Grant is well-qualified to undertake pre-purchase and building inspections.

As a proud Marlburian, Grant enjoys all the region has to offer, and with the Marlborough Sounds a stone’s throw away, can often be found boating and fishing. A dedicated family man (Dad of 4 and Grand-dad of 2) and a keen member of the Marlborough Vintage Musseleers Golden Oldie’s Rugby Team, Grant also has a love of travel and exploring the world, so it’s just as well his wife has a Travel Agency!
