Brad was Knight in shinning amour, when I took over more retail space and needed, a wall up and walls down and new racking put up, Brad and his team came in and worked fast and professionally, they left the place immaculate,and looking fabulous, and in a timely manner to get my business reopen. I wouldn't ever hesitate to use him and his team again. One of life treasures, always willing to go above and beyond 🙏 Sassy Sadie Waihi

I recently had a deck built by Black Line Development, and I couldn’t be more impressed. Brad and the team were fantastic—professional, knowledgeable, and genuinely easy to deal with.

They really listened to my ideas and concerns before the build, offering great advice and options along the way. What I had in my head, they managed to turn into something real—and better than I imagined.

Quality work, clear communication, and a team that cares. Highly recommend Black Line Development!

We had a fantastic experience with Blackline Development. The team was friendly, efficient, and incredibly professional from start to finish. The quality of their work is outstanding — every detail was finished to the highest standard. Not only do they build beautifully, but their landscaping work really brought everything together.
