Ryan Koster (Owner)-  I started this company to serve the greater Des  Moines area as a premiere Residential Building Company. My vision is simple, I want to provide the highest quality product and service that my clients deserve. We treat every project as if it's our own home. I have learned that great service begins and ends with experienced and friendly professionals. I believe that my team and our subcontractors can provide the best in the business, and have complete and total confidence in every person working on my job sites. Platinum Design Build, LLC. finishes each project on schedule and with the highest level of quality. With a focus on personalized service, competitive rates and customer satisfaction, we’re always striving to meet and exceed expectations. My goal is to provide you with an experience that puts your budget and vision in the forefront and be a true Design + Build company. I will work with you one-on-one to design your project inside and out, then take the project all the way to completion with the build process.
