→  About:

subject/matter is an architecture and design studio based in Columbus, OH. Our passion is crafting new relationships between people, spaces, and materials. We work at a variety of scales. 

Architecture matters at subject/matter studio.

We develop designs that are bold, lyrical, and optimistic about the future. Our studio was founded in Columbus, Ohio with the ambition of developing innovative projects for like-minded clients in the Midwest and beyond. Our work has been featured in Architect magazine and the Architect’s Newspaper, and we’ve exhibited widely. The studio is led by Justin Diles, AIA who is also Associate Professor of Architecture at The Ohio State University. 

We shape materials/materials shape us. This relationship animates our practice. We are hands-on. We enjoy designing buildings and fabricating special projects to test the boundaries of what is possible.

We’d love to talk with you about your project. Contact us!
