Perhaps you can divide the space. Possibly using the sofa as the room divider between kids and adult/family space. Defined storage for games and toys and strict rules for kids that they must pick up and toys stay on kids side at all times. Win that battle now.

there is no photos till now, its still under construction but i am looking for ideas to do this job.
really i need more photos to imagine that.

Oh, okay...I understand. :) Can you give an idea of the size of the room? I will hunt around and see if I can find some inspiration for you. :)

3 meters * 4 meters

Hi again. :) Do you have the sofa already? size?

please,, there is no any way for chatting,, i can't post along comments. :( :(

Okay, I will just leave some ideas for you then. :)

Thanks alot,, I appreciate your help :)

Few ideas....not necessarily for color....but notice the use of storage and my suggestion would be more closed units or basket storage to hide things when not in use. Also, combining more adult lighting and end table, coffee table/storage type ottoman will add to a more sophisticated space. If that's what you're after.....I'm not sure? Good luck, I hope this helps.......
