When Siegal wanted to integrate a discarded tractor-trailer into her own home, she turned to Hype Arc. The firm, which partners with architects and other industry pros on an array of projects, helped with the custom steel-and-glass doors that connect Siegal's instant addition to the backyard. Hype Arc also fabricates architectural components such as stairs, doors, and countertops. Hype Arc Design + Build, 310.333.0898; www.hypearc.com
