It may not be very popular in the tropical or the warmer countries, but in cold countries, having a sun room is very essential. People in the colder countries wait eagerly for a sunny day and when that bright day comes, they want to enjoy it to the fullest. Therefore, they make an entirely separate room in their house where they can enjoy the sun. This room sin own as the sun room.
It is only obvious that the sun room has to be spacious and a lot of light should come in. therefore, the design of the room would be best if it done in the form of a patio or deck. Then, you can keep easy chairs where you can relax with drinks and keep your legs rested on the deck and enjoy the sun all day long. Remember, there is no point in making a sun room if enough light is not entering the area.
