I've done them in two places:

1) In my office in front of my desk (looked at my desktop computer, which is an iMac)

2) In my guest room, with my laptop on the floor.

You can get away with a pretty small amount of space in a pinch.

The playroom! I tell my kids - "Mommy's doing Pilates in the playroom tomorrow morning. Go make sure all your toys are picked up!"

In my office in front of my desk is where I do my mat classes. I have to get a laptop so I can take it into the spare bedroom where my reformer lives.

In my living room... Same as Cynthia, I make my family clean up their mess first. This way Pilates keeps me fit and my house clean!

I'm on vacation right now and getting ready to teach class out on the dock to my friends! You really can do Pilates anywhere and anytime!!! I also take classes in my living room (must move coffee table etc..) and hotel floors all over.

Pilates class on the dock!

Love the dock class! I hope you video taped?

Home gym over our garage with elliptical, weight machine for my husband, Stott Reformer and 60" TV for PA. Room is mirrored on two walls so we can check form. Grateful to God for strong body so I can work hard to relieve stress.

In my home studio with a BB reformer, chair, spribgboard and a spine corrector:))

Wow, the 60" TV sounds great. Would love to see a photo of that setup.
