About Great Divide Home Builders

Rob Martin, owner of Great Divide Home Builders has been building custom homes for over 30 years. With a background in architecture and the skill that comes with many years of experience, our homes are not only beautiful and functional but meticulous in detail.

If you're thinking of building your dream home, you might have a picture of that home in your mind. You've probably even collected a few photos of different architectural or design elements you like: a sprawling front porch, an airy cook's kitchen, a loft with a family room. But is it possible to make all the ideas you've collected work together? How will you know if that porch, kitchen and loft can be combined into a cohesive design?

That's where we at Great Divide Home Builders come in. Because we do all our own design work using three-dimensional software, you can see exactly how your custom home looks before we ever break ground at the building site. We work very carefully on our plans working towards nice, open, flowing plans that reflect the artistic vision of the home owner. We at Great Divide also pay close attention to the trend toward homes that have less environmental impact meeting or exceeding Energy Star efficiency standards. The results are houses that are incredibly workable and suited to Montana's environment and landscape.

“We found Rob's work to be of unsurpassed quality with exceptional attention paid to detail. Door hardware and bath accessories were matched to the lighting fixtures we chose. Adjustments were made in the kitchen cabinetry and plumbing fixtures to fit with the appliances we chose. The fireplace was finished according to our wishes, and the door styles chosen matched the architectural features of the home.

We were able to work with Rob largely through e-mail and phone over a distance of 1200 miles. When we arrived in Helena, our new home was exactly what we had envisioned.”

“I wanted to thank you for the great job you did remodeling/adding on to our house and building the deck. This has been the easiest building process I have ever experienced and I have built many homes. Living in southern California and being able to trust someone 1200 miles away is difficult but you had that trust and delivered a quality product. The quality of your work is outstanding and the attention to detail exemplary. Your bid was fair and complete and the only change orders were for changes I requested. You also delivered when you said you would even when the road conditions were bad. You were also very helpful with ideas to make the addition have the same feel and look as the rest of the house. Thank you again for your hard work and please feel free to use me as a reference anytime.”
