Balcony is mainly designed for residents to do outdoor activities and hang clothes. The balcony is an extension of the interior of the building, where residents breathe fresh air, dry clothes and place potted plants. Its design needs to take into account the principles of practicality and beauty.

There are generally three kinds of balconies: cantilever, embedded and corner. Balcony is not only a place for residents to receive light, absorb fresh air, do outdoor sports, watch and enjoy cool and dry clothes, but also a pleasant small garden if properly arranged, so that people can enjoy the cutest colors in nature and breathe fresh and fragrant air without leaving home.

Very noisy. The sound at the bottom changes with the change of environment. Although the ground floor may be quiet, the noise may be loud. This may be the disadvantage of the balcony.
