This is more for washing than doing business, whatever business you might want to do. Make sure you can clean yourself, your dishes and your clothes in this if you want or need to.
Paint your window box with bright paint. Plant some vegetables. Plant all different flowers. Repeat some or all steps if there is more than one window box.
Plant flowers and get a deck chair or bench. Put up a bird house and bird feeder if you want. Try putting up a small washing line to dry clothes. Get garden toys such as a hula hoop, small paddling pool, a ball etc.
Get some potted plants. Get two chairs and a table. Consider putting up a small washing line on your balcony to dry clothes.
