After working together for more than three decades on some of the world’s most recognizable casino resorts, Tony Marnell and architect David Howryla are entering a new chapter.

The two officially formed Marnell Howryla Architecture last fall, positioning the firm to carry one of Las Vegas’ most influential design legacies into the future.

The partnership formalizes a relationship that began in 1994, when Howryla joined Marnell Companies as a young architect. Since then, the pair has helped shape projects including Bellagio, Wynn Las Vegas, M Resort and resorts around the world.

Marnell said the partnership represents the next chapter of his company’s story.
