At East Slope, we believe successful projects come from good collaboration – both with you the client, and the contractors. During our ‘Construction Obersevation’ phase we make sure the design intent is followed through to completion.

    » Review 3D models

Design Development

Time Length: ~ 8 Weeks

  • Explore the details of the project further

About East Slope

Lead Architect + Craftsman, Ryan Costner

Ryan is a licensed Architect in Colorado who earned a degree in Environmental Design focusing on Architecture from CU Boulder. During his 15-year career as an Architect, he has developed expertise in using 3D design as a tool for design and communication. Ryan has extensive experience in designing custom residential projects, including both remodels and new builds. He has also designed commercial spaces such as a climbing gym, breweries, restaurants, multi-family homes, and offices. In recognition of his residential design work, Colorado Home and Lifestyles Magazine awarded him the Five Under Forty Design Award in 2019.

Ryan’s passion for craftsmanship began at a young age when he used to build furniture with his dad in the driveway. He has carried this hobby and passion throughout his life and continues to push his designs and construction techniques to higher standards. His pieces are built to last and intended to become handed-down heirlooms, honoring the quality of the hardwood trees they come from. Multi-generational furniture supports a sustainable future, which is what Ryan strives to achieve through his work.

Ryan’s plans for East Slope Design Studios involve designing structures with thoughtful, sustainable designs. He intends to use the latest construction methods and material science technologies to achieve this.
