A comprehensive approach to design and implementation of the plans would benefit you in this case. A team of interior designer, contractor and possibly architect (if walls are moving or there is a more involved construction plan beyond decorating what is there and dealing with functional issues related to the interior design). Sequencing of trades and scheduling is the job of the contractor while providing costs for the implementation of design work. Designing and dreaming up solutions is the job of the architect and interior designer. Using a team approach with egos left at the door will give you a doable design, a solid budget and a reliable schedule. Best of luck with your project!

So for this to work, you need to go back through my question and make sure you have answered all of them the best you can. Is the electrical outlet for the counter space going to be right next to the switch, or is it that blurred spot that I see in the picture, . If your walls are Travertine marble, and there are not already electrical boxes in the exact location the lights go, we are going to have a hard time. If a 30" vanity goes in the corner, and you leave 5" on each side for the lights, that leaves a 20" mirror with one light jammed tight into the corner. So if we leave another inch on both sides, for clearance, that leaves 18" mirror. If you put a 3" frame around the mirror mirror, that only allows for 12" of actual mirror. I don't think that is enough mirror. Your bath is too narrow for a mirrored cabinet with built in lights unless it is recessed into th wall. The plumbing is probably in the way for that. Give me your thoughts on what I have just said, and then go back and answer all my questions. Then we can take it from there with a narrower down and focused search.

Change the pipes which material won't get rusty and corrosion, plastic or PVC is suitable. I think concealed rain shower system is more perfect for your bathroom. Check the link and choose the ideal set: http://www.homary.com/shower-faucets-shower-systems_c157

coming to the dining area..yes id say you remove the seating entirely and concentrate on a foyer area since you already have space for a drawing room on the floor.. id suggest erecting a glass and marble wall in line with the wall that runs between the pooja room and the bedroom..say a bit of marble-glass-marble-glass-marble.in this case you have a small foyer area demarcated by this wall feature.you can deck it up by placing a nice console table in front of the central marble wall with a nice mirror to reflect the space and make it look larger or a sculpture with beautiful bracket lights on either side to accentuate the same.and on the backside of this wall you could have a crockery unit with a huge painting or a cluster of family snaps above it. if you could brief me a little on the look you're adapting for your house i could suggest some more treatments for the walls.if you want to avoid using too much marble you could also opt for a marble wood and glass look where you could take out some concealed storage for shoes etc. regarding the drawing room - what about a huge 4 seater in the center instead of 2 - two seaters with a table in the middle as in the plan..if you remove the central coffee table maybe you could replace the single seater with a chaise for 2 and also replace the 2 center tables with a nice long table in the center with an area rug running below it..if you could help me with the room dimensions maybe we could add 2 pouffes in front of the 4 seater so it creates more seating and doesnt obstruct the view if you plan to put a TV on the wall. what look do you have in mind for your terrace garden ? something zen or a little rustic toeing on the lines of the contemporary ? sorry for the late reply as i was travelling.. hope this helps! :)
