About IBI Builders

At IBI Builders, we’re sure to keep your functional and aesthetic needs in mind as well as your budget needs when building your new home or remodeling your current one. Founder Greg Grissner’s approach to pricing derives from a flat percentage of the value of your new home. Unlike many builders, Greg does not add in additional costs through mark-ups on materials or subcontractors – which allows IBI the assurance to clients that they are getting the best quality home for the best price. This ‘open book’ approach allows IBI to work with you without having a biased view on any additions or changes to the design of your home.

Experienced Custom New Home Builders

With IBI Builders, you have direct access to Greg during all the stages of the construction of your new home, providing a level of customer interaction few builders can match. He is a hands-on owner who keeps his attention on your details, his eyes your vision, and his diligence on your budget. He takes great pride in making sure that his customer’s satisfaction is guaranteed.

IBI Builders has developed such confidence in two of our home buyers, who are partners in an architectural firm, that they now invite our team to be part of the design phase of other projects. They trust and value our integrity and creativity as well as our ability to see outside the box. For examples of our work, visit our gallery for a virtual tour of past homes or review our client testimonials to read about the experiences of previous home buyers.
