Brighter room gives an illusion of a bigger space. To get more natural light you can add windows or install a bigger size window or install a skylight. Skylight makes a room brighter with natural light and the room feels more open and airy. It comes in different shapes and sizes. You can plan a weekend DIY project by installing a small skylight like this. Since it’s small, you don’t have to worry about the heat too much. It looks like a recess lighting with no electricity.
Or you can bring the outdoor feeling inside by installing a big skylight in your living room or bedroom, like this. You can see the sky and clouds from the comfort of your sofa or bed.
With the skylight that big, you can count the stars if you have trouble sleeping =). The downsides with this big size skylight are the room can be overheated by the sun exposure and it’s really not helping if you like to sleep in on the weekend or holidays. To control the light and heat, you can install a motorized retractable shade, like this.
Skylight is definitely an energy saver and definitely a plus if this can be incorporated to any room design =). Here are some more pictures for your inspiration =).
