Top 100 US Architecture Firms according to Architect Magazine

Architect Magazine listed the Top 100 U.S. firms based not just on their size, but on three elemental and critical aspects of each one: profitability (revenue per employee, based on 2008 gross revenue), sustainability (with variables such as percentage of LEED projects in 2008 and green policies) and design quality (based on awards on 2008).

Some of this practice have been featured on ArchDaily like Skidmore, Owings & Merrill, Perkins Eastman & SHoP Architects.

    I had never even heard of William Rawn Associates before.

  • ashok

    william rawn!???

  • sbtrct

    I have heard of five of these firms, and three of those five are in the top four. Admittedly, I work in Europe, but still…

    A casual perusal of randomly chosen links reveals a common thread – a distinctly average collection of large scale built work. I suspect the profitability of these firms was weighted more favourably than the other criteria. Not exactly the raison-d’être of this blog.

  • Jason

    no REX.. no Mrophosis.. really?
    what a joke!

  • h

    William Rawn would be the last of my concerns. They actually do very nice work. Are thye tops? No. But they could be top 100. Just a very brief look at the firms from the bottom up….Look at no. 98,99 & 100. Holy craptastical!

  • ripbang

    this list is nutty; if you’ll take look at the full article in the magazine, the way the rankings were determined leave so much room for ambiguity. the rankings are based on the self professed “Revenue per Employee”, percentage of leed APs/Green Projects, and ’08 awards received. the surveys were completed by the firms themselves and leave plenty of room for “embellishment”. it is also worth noting that some of the firms listed in the top 100 have completely imploded this year. For example, DLR has 200 points for having revenue of $100-199.9 million. That’s a pretty broad range of revenue, no?
    good luck with that, everyone….

  • ripbang

    SOM is listed at #2, but I heard that they closed almost the entire LA office early last year. Jerde is listed at #48(?!) and they dwindled from about 110 employees to around 30 in a matter of months. i’m sure that there are similar stories across the boards. what a sad state of affairs.

    But forget the money, we’re in this for the fame and the glory, right?

  • vincenzo

    where is Steven Holl? Maybe he is Japanese…

  • Daniel Con

    What a JOKE!

  • nono

    What about Pelli Clarke Pelli Architects?!

    • zomboy


  • biboarchitect

    morphosis isn’t one of them???

    • j

      exactly my sentiments… what a letdown

  • javi

    where is KPF?

    The Architect’s Journal in the UK have just unveiled their AJ100 interactive list of the UK’s biggest practices:

  • Katsudon

    Ah… got it!


    “Ok guys i’m about to push Enter key.”

  • hairpiece

    If you read their criteria this list is based on:
    1. Profitability
    2. Number of LEED projects
    3. Number of Design Awards

    First of all, not all offices publish their profit information. So, this list is already limited to those offices chose to share how much money they made this year, or are publicly traded (which aren’t most). Do you think REX or Morphosis want to share their profit information? What would their interns think? It’d be mutiny for sure.

    Secondly, the number of LEED projects is also in a way subjective. What if I work on three very large projects, but another office works on five which are a fraction of the total square footage? Also, what if the buildings I design are environmentally friendly, but not LEED? Sure sustainability is important, but a better measure would be an actual direct measure of energy conservation.

    And finally, design awards…sigh…what can I say about design awards? Most tend to be as flawed as this list. So now you have a subjective ranking of subjective awards… Is an AIA Gold award weighted more than an local government award? What if I win the Pritzker that year, but nothing else, and another firm wins 3 no-name awards? How do you know if one award is “harder” to win than another? What about B.S. professional organizations like SARA which only exist to give their members awards and beef up their resumes?

    Finally, my last point, and most intellectual of the bunch…list a just dumb to begin with.

  • EHDD Architecture

    EHDD ranks No. 20 among architecture firms

  • Bbay

    what the heck, Gensler lost #1? I’ve always assumed they held that spot for a while, but to put them as #13? Did I miss something? did they downsize or perhaps gotten into some trouble I didn’t know about?

  • Jeff Frame

    Creating a top 100 list is not easy, and who gets the top spot really depends on the person creating the list. So it’s hard to rely on lists even if they are so called “official lists” since rankings would vary from one criteria to the other. But this is a good guide. At least we know which ones are vying for the top spot.

    • olayinka olamilehin

      can someone rate this list in percentage and suggest a better one, so that we can know the true best 50.
