Work that Matters

LHB gives talented professionals in architecture, engineering, and planning a chance to do their best work. We encourage innovation and ambition, and our multifaceted portfolio is deep and diverse–offering staff a chance to explore nearly every aspect of the design profession. From bridges and buildings to highways and pipelines, our projects allow designers to explore, experiment, and excel.


Driven by Curiosity

Finding the right solution to a problem begins with asking the right questions. We value curiosity and ingenuity. We have enough experience in design to know that the best answers are rarely the easy ones. The LHB team is humble, dedicated, creative, and always looking for better answers–fresh ideas and approaches that can serve clients, improve experiences, and maybe even change the world.
