Many regional design firms enjoyed Texas-size gains in revenues last year, with the wealth spread among both large and mid-size firms of virtually all stripes. Of 2014's Top 50 firms, a full 80% reported revenue gains over 2013, a reflection of brisker business in the region, particularly in the Lone Star state.

Significant gains also were made among many of the region's Top 100 firms, so we've extended the list to share their accomplishments last year with ENR readers.

We'll have much, much more to report about the region's Top Design Firms in the June 15 edition of ENR Texas & Louisiana, including a ranked listing of the Top 100.

Meantime, what follows is an alphabetical listing of them, as determined by 2014 revenues.
