To begin with, it would be large and airy, with tall windows at regular intervals along the wall, to let the daylight in. Curtains, easy to pull and adjust, would hang at these windows, so there would never need to be a glare of the blinding sun at any hour of the day, but only soft light filtering through the cloth.
Comfortable seating would be the next essential in this room. Comfortable couches and saggy arm-chairs would need to fill the space of the room, just beckoning and waiting to be sat on, sprawled upon or even fallen asleep on. The seating must be the type to make even the heartiest and most energetic feel as if they’d like to sink into the pillows and take a little nap.
Next, the lighting. While there must be some sort of strong central light, it shouldn’t be needed most of the time because of the many small lamps, hung with crimson or orange shades so as to cast a comfy, romantic glow. There must be a big, heavy, wooden desk with a good and upright desk chair to go with it.
Lastly, and most importantly – books. The walls are shelves, leaving not one empty space for a picture or hanging. The books are both the adornment and the purpose of the room. Their smell fills every nook and cranny and their soft murmurings are ever present, demanding quietly that you pluck them out of the shelves and lose yourself in them.
This would be my perfect room, and if I ever get enough money to own a house, I’m definitely going to try to create it.
