The verandah is one spot of your house where you might wish to relax and spend some time alone while thinking about something important or just relaxing your body and soul. If you have adequate space in your verandah to add a swing, go ahead. It would be a pleasant experience to be seated on a swing while relaxing. You can even doze off on the swing while the cool breeze in the verandah keeps you comfy.
If you have a small family then installing a swing with a single seat would be good enough, but a big family may need a larger swing. There are those long swings which can easily accommodate three to four persons at a time; you can get one of those. You will need good enough space for the larger swings as they would otherwise make the verandah look congested. A swing in the verandah is a very good option.
