I have a commercial building for our daycare centre. We have a front entrance with two washrooms, coat hooks, shoe rack. Then we have a preschool area (apprx. 500 sq ft) this is seperated by a small wall into the toddler area (another 400 sq. ft) and then we have an infant area (500 sq. ft) that is a complete seperate area (as they sleep more). We also have a 3600 sq. ft outdoor play area. Total of 36 children and each "room" has two caregivers.
The caregivers have an admin area as well, but it's only about 200 sq. ft.
