Grendahl Design Company is a design build firm that provides new build construction homes in the Bismarck Mandan area. We are a husband and wife team that thrive together and in the building process. We will design and manage your project from concept to completion.

Roger is the project manager of the homes, and he is hands on during the construction process. He makes sure the projects run smoothly and in a timely fashion. He has a background of 18 years plus in the construction industry, and runs a successful electrical business RG Electric Inc. He has overseen many large projects, and has managed several new construction house projects.

Sarah brings the style (that’s me!) and design. She has a degree in Interior design, and designing homes is her passion. She designs everything from the floor plan and up. Craftsman Coastal design is her favorite design style. She is educated in the Chief Architect program to design and draft custom house plans. Her interior design background allows her to guide clients through the design process. Your home should tell your story, and she loves helping a family bring their story to life.

We use the best computer software to help show clients views their home before construction even begins.

We also use reputable sub contractors and run a project that maintains a good working schedule. We work closely with homeowners to design and create their dream home, while guiding them through all the big decisions and design process.
