GC's who like to do modern

So, we are working on an addition/remodel of our 1951 modern ranch house... we plan on adding on about 750-800 sqft. I talked with a very highly reccomended GC's, but he wasn't so keen on flat roofs.. nor did he see value in concrete floors... Does anyone have a reccomendation of GC's in the portland area who like modern design.. and would like to tackle such a project?

Thanks!

try scott at White Dog Construction. he did the doug fir and is excited by all things modern...
