I feel theatre room should be very dark and soundproof as well. Because when you watch a movie there has to be dark in your surrounding area then only you will able to watch movie happily.

Some creative things have to be there when we are planning anything for children. As they learn what they see so better to make things in a proper way and something which they can grasp knowledge in a good manner.:-D

I prefer instead of purchasing furniture I would make custom-made furniture. As it will be as costly as ready but custom-made will be according to our requirement and design as well.

These custom designs are so costly better to go with custom or 3D painted tiles which are less costlier than these custom shaped design tiles. (Not oppose to anyone)

In TV room & Bedroom, there should be soft rug which will give good feel and look. On the first floor, you can keep marble (Color according to your choice) and same can be in the bathroom.
