I love the idea of creating exceptional tiny/small outdoor spaces. A plant, seating (bench or chair), small outdoor rug and a candle = retreat. Use your small space anyway that makes you happy whether it's a potted garden, outdoor grilling, or a mini gym. If needed, you can had privacy to your balcony with hanging shades, tall plants, or by weaving canvas like materials through metal railings. The view your balcony from the inside of your home should put a smile on your face.
Below are "a few photos" of tiny/small balconies on my Pinterest account:
I hope some of these photos will inspire you to create a exceptional space for your balcony.
Remember to be kind!
