An award-winning design + build firm devoted to green building, urban living, and improving quality of life for our clients and the well being of the community.

Otogawa-Anschel Design/Build — known as OA Design+Build+Architecture — is a Minneapolis-based firm with over three decades of experience transforming homes through integrated design and construction. We are an award-winning practice devoted to green building, urban living, and the belief that sustainability and beauty are not in conflict — they are inseparable.
Our model is unique: we offer full architectural services, interior design, and our own carpentry and construction team under one roof. This integrated approach means that the people who design your home are the same people who build it — resulting in better outcomes, fewer surprises, and a level of craft that is difficult to achieve through traditional contracting.
Our mission is simple: to improve quality of life for our clients and the well being of the community. We pursue that mission through beautiful, resilient, efficient, and healthy design — from the hidden wall systems to the finely crafted finishes.

Integrated interior design services that ensure every material, finish, and detail is thoughtfully considered and cohesively executed — from flooring to fixtures.
Our own carpenters and production team execute every project with the same care and craftsmanship as the design. No subcontracting the work that matters most.
Green building and environmental stewardship are not add-ons at OA — they are the foundation of every design decision we make.
We believe in the power of local craftspeople, local materials, and local knowledge. Our work improves not just individual homes but the communities they are part of.
Beautiful homes should also be healthy homes. We prioritize materials and systems that support indoor air quality, durability, and long-term well-being.
Every client, every home, every neighborhood is different. Our process is designed to find the best solution for you — not to apply a formula.
