My house is turning 100 this year. We have a screened side porch that is connected to the home through french doors in the living room and french doors in the master bedrrom. We are planning another child and I would like to stay home. While at home, my plan for income is to open a small at home daycar. I would like to close in this screened porch and create an area where I could have the at home day care. What is good advice about closing this area in.
