Lionel Morrison and Mark Dilworth began their architectural careers in 1977 as architectural interns at the same firm in Dallas. Eventually their career paths diverged but each achieved great success in his own right. In 2010 they rejoined and along with Cari Walls formed Morrison Dilworth + Walls for the purpose of producing outstanding architecture for discerning clients.

The principals are highly respected professionals having consistently won design awards for office, residential and retail projects with budgets ranging from $2,700 to $150,000,000. They are frequently published in national and international periodicals and books.

Mr. Dilworth and Mr. Morrison are responsible for the design of two of Dallas' most recognizable icons: the new NorthPark Center and One Arts Plaza in the heart of the Dallas Arts District.

The firm's principals are well-versed in the science and art of building and bring to their clients considerable energy, expertise and talent. To Morrison Dilworth + Walls the only successful projects are those that achieve their financial, civic and architectural goals while exceeding their clients' expectations.
