One has to appreciate that all these apartments, condos, co-ops are designed the same way. Everyone has a balcony. If you have a balcony you usually have a patio door. How do you decorate these small spaces? The sky is open to everybody. Blue skies, cloudy skies, stormy skies, gray skies. Have you underlined this outdoor view with a pretty scape of our own? How you decorate you indoor rooms usually reflects how you will decorate your outdoor space. Take your clues from there. Same style, same color scheme. It’s ok to break the rules, but usually it’s good to keep your eye moving easily from one room to the next. If you have a neutral room in one or the other, you could add a splashy color.
Being able to step outside and inhale the fresh air is an enormous experience. If you have a table and chair and you can sit with a cup of coffee or a glass of wine ( any drink of your preference). Decorate with a pot or pots of flowers makes a tiny space, a beautiful space to relax, to visit, to review.
Tending a garden is a very therapeutic occupation. Having foliage around and in your home is very healthy. Lots of good reasons to take advantage of the space immediately outside your windows/doors. It does take time to find what plants work well for any location. Keep trying, you will find a lovely assortment of greens before too long. Ask your neighbors or your local nursery what might work.
