No @sueinmn, no windows. Just the sliding barn door. We placed screened-in vents near the roofline to allow for ventilation. He told me he thought a treadmill might be more conducive for me getting out and walking, also, because I wouldn't be so concerned with uneven surfaces with my stability issues. I use walking sticks every time, and put on my lightweight hiking shoes for good support. Getting outside, I like to look around, and listen to the world. I figure when the weather turns bad with rain or snow, I can "gerbil walk" in the house! At least we have windows!
