With over 20 years of experience—including time under renowned architect Lionel Morrison—Nimmo has designed standout residences across Preston Hollow, Bluffview, and Urban Reserve.
His philosophy blends beauty with ecological sensitivity, using passive systems, minimal-impact foundations, and seamless indoor-outdoor integration.

Thad Reeves - A.GRUPPO Architecture
Thad Reeves is co-founder of A. GRUPPO Architects, a Texas-based firm known for inventive, material-driven residential design. With a background from UT Arlington and two decades of experience, Reeves has helped shape modern Texas architecture through precision, craft, and collaboration. His award-winning homes, including those in Dallas’s Urban Reserve, emphasize clarity, restraint, and spatial richness.
Reeves views architecture as an experiential art—responding to site, light, client, and material. His designs often reveal themselves through layered details like warm concrete walls, cantilevered forms, and precise window placement.
In Forest Hills, Reeves applies this philosophy to a residence that embraces the natural landscape while offering modern clarity, comfort, and enduring design.
