I use my whole house for my program but the main play area is in my basement - I had a large window installed in the stairway for the additional fire exit because my normal windows were not large enough to meet the fire code bilaws for operating a 'business' down there and that really helps to let light down into the basement in general and make it not feel well 'dank' and I also painted it a pale shade of yellow and added lots of lighting so it does not feel like a 'basement' ... but even still I too personally do not like to spend ALL day down there as a dedicated space ... we play in my main floor family room as well and it up in the kitchen and so forth and well to be honest we spend most of our day outside as long as the weather permits and I just offer all my 'program' out there from art to story time under a tree
