In what country are you building this house? 9 foot or vaulted ceilings are taller than the US builder average of only 8 feet (this is the distance from the ground to the ceiling). If you have a small room, having a higher ceiling (even only 1 foot extra) will make the room feel more open and airy. In a small house of 1500 square feet, having high ceilings would go a long way in making it feel much larger than it really is. It is especially beneficial in a hot climate because heat rises so you will spend less on cooling costs. It is not so beneficial in a cold climate. It still looks nice, though!

Give the room a THEME to give life to a room . This white design looks brilliant just add some colorful pillows and a small tv and picture frames on wall . Also add a colorful ottoman or upholstered chair . For more inspiration Check Maharaja Express compartment interiors pictures ;)

Send a rough sketch with measurements . IT'll be easy. And do you want it to be bed cum study?

Ravi, Are you planning just a small room or would you have a pooja cabinet as well in the room. You may need more space for a seated pooja arrangement and often you have multiple people while pooja. Decimal measures are just fine no such constraints that I am aware of. Thanks, Nitin. Cornerstone Designs, Bangalore.
