On the new season of “Mad Men,” Don Draper and the rest of the crew have new digs in the Wallace Harrison-designed Time-Life Building. Anyone looking for their own mid-century office space? I came across Technical Service Park on Linden Lane in Silver Spring a few weeks ago by chance. I’m glad I did. When I first saw the office building with its vintage stone sign and concrete screen block decorated exterior walls, I thought I had taken a detour to LA, Palm Springs or Vegas. If anyone is looking for office space in a mid-century modern building, you can see what is available here (scroll down to the Silver Spring listings.) If you’re not looking for office, at least you can enjoy the pictures of the this well-preserved (at least on the outside) local mid-century commercial space. Speaking of Harrison, stay tuned for a report on my visit to his Empire State Plaza in Albany.
