I live in Minnesota and United Health Care has done both. they've bought newer buildings that were vacated and just built a huge (72 acres) campus on the outskirts of the city: http://www.bizjournals.com/twincities/print-edition/2011/09/02/uhg-to-create-72-acre-campus.html http://www.bizjournals.com/twincities/print-edition/2011/09/... Cargill several years ago built a huge new campus at an abandoned Super Value production plant: http://www.opus-group.com/OurWork/Excelsior-Crossings http://www.opus-group.com/OurWork/Excelsior-Crossings Also, I've seen older 1970's corporate buildings demolished and there's an area in a nearby suburb where they're trying to rejuvenate the area where nearly all the buildings are empty with a $500 million project plan: Demolition: http://hillcrestdevelopment.com/pentagon-park-south-tower-demolition/ http://hillcrestdevelopment.com/pentagon-park-south-tower-de...
