Its a really lovely room! what a great place for kids to share. I like kids sharing rooms. I think you need another colour to tie it together. I would suggest a blue tone.... teal, navy blue, duck egg blue. to tie it together. Its a little to pale and looks sparse, but actually isn't. I would leave everything exactly as is, BUT, paint the back wall behind the bed teal and find a simple navy blue wall decal that is fun and kid- like maybe one with a sillouette of a boy and girl playing. I would paint the wall behind the sofa duck egg blue. Then I think it would suit both kids more and look more kid friendly. the blues will balance the pink and cream, but because you have a pale carpet i don't think it will look too dark. don't worry about making it totally kid like, its a room they will grow with, not a kindergarten, and it also needs to peaceful and restful for sleeping. besides with their art on the walls and bright toys everywhere it soon looks bright and kid like. Good luck!

haha you have a great problem! refer to the attached sketch plan,roughly 12'x6'10" will be your kitchen and utility you can accommodate a fridge, a washing machine, sink for washing utensils. keep it combined kitchen + utility. for guest bedroom, bathroom will be 4'x6'10" exactly, comfortable and as per standards. and my suggestion would be keep the living as living as by going the changes to kichen area you will get a wall where you can mount a TV . and placing a small dining table will serve as breakfast table, and also use your dining room as a study our your own personal leisure space. and about the costing part, there will be a lot of civil work involved , demolition, water proofing of new bathroom, plumbing for bathroom, new accessories new tiles. consider a range amount of 10 lakhs to 20 lakhs depending upon finish, chosen contractor rates and specifications. these are very rough figures.

you have to elaborate on the cinema kit you plan to set up. pls share the specs and details of the space

Many thanks for your valuable comments. 1. My intention of raised cabinets was to clean it daily, as cabinets that touch floor accumulate lot of dust and food particles below. If we rule out steel legs, any inputs on raised floor only of cabinet area and then cabinets?(Just like plinth in modular cabinets- but this will be permanent and of tiles) I have not seen such structure anywhere, so curious if it will work. Otherwise I will go with traditional ones. 2. Moving pooja out of kitchen is very difficult as other rooms are just enough for their function. Currently a small Mandir is attached on wall where Fridge is shown in layout. I thought the new area could be little extra for all pooja related things. Will like to know the reason of your recommendation, is it odd in whole design, or not suitable in area .. or anything else? How about moving it to corner of dining area?
