Our Team

Brian Karr

With a strong business vision, determination and natural ability for construction, Brian Karr began his home building career in 1999 and he currently owns Holz & Stein Custom Homes (holzandstein.build). It was then that Brian quickly envisioned changes in the flooring and countertop areas of home design. Thus, Holz & Stein Architectural Surfaces was formed.

“I wanted to reshape the look and feel of wood floors and countertops and bring a European look and design to DFW.  Our floors make bold, distinctive design statements for the contemporary and transitional home”, Brian proudly shares. Brian’s family migrated from Germany in the early 1900’s and settled in West Texas.  Brian grew up in Amarillo, Texas and attended West Texas A&M University and has lived in Dallas since 1999.
