  1. Thumb up Thumb down 0

    I can’t believe that a list of the “Top 250 US Architectural Firms” is based solely on revenue.

    In millions.


  2. Thumb up Thumb down 0


    An accountant must’ve compiled this list, or someone that could tell the difference between BIG NUMBERS and small numbers. not Architecture.

  3. Thumb up Thumb down 0

    for all who will complain that its based on revenue

    what? are you gonna tell me that you dont want to be on this list?? i’d love to be, hell i PLAN to be

    • Thumb up Thumb down 0

      These aren`t necessarily most caring about staff either. Could be managers and shareholders make them top the list.

    • Thumb up Thumb down -1

      If you want to be on that list then you are not an architect. Don’t read archdaily. read economist and design ugly buildings.

      • Thumb up Thumb down +2

        I’ve worked at two of those firms – probably did more designing there than at my current smaller firm. Debating going back to one.

  4. Thumb up Thumb down 0

    The firm I work for has risen substantially on this list. There isn’t a firm or a company out there that cares more about their people than my firm. We also design superb, cost-effective facilities and have a tremendously talented staff. I am not management or owner either just a very happy employee.

  5. Thumb up Thumb down 0

    Try to look at it this way, and understand that the larger revenue (thru AR services) means more projects done/completed… the more those firms practiced architecture during the time of survey.
