It seems to be Teak, which is a quite expensive wood. Lots of Yachts and Boats are made of Teak and it is used widely on decks, so, I still dont understand what your question is? What you are saying, is that because of the electrical and AC Vent, you need to drop the ceiling? Do you have straight walls/ceiling? can the wood be attached to the existing ceiling? The Carpenter installing the wood, could just lower the AC Vent and what kind of electrical are you talking about? The ceiling can lights?

Well I'll try to make a 3d of the room and upload it. But that will take some time. Thank you :)

Hi, I am from Assam, Guwahati. Yes it is warm humid place with lot of rains (like kerala). The bookcase is gradually drying. Fortunately last few days were very sunny and airy and my room has two big windows. Few mor details of my bookcase. It is 8 feet wide, 6 feet tall and 11 inch deep. It was attached with wall with 6 wall screw and has four pair of legs.I ask the carpenter to divide the bookcase into 3 part (32 inch each) and two door system for each part. Every part has 6 shelve from top to botom. There is no plywood or wood in back. I made it that way because the bookcase is attached in my room's inner wall I understand that the bookcase may have very little gap in between wall and wooden planks and i am ready for it. But I have no idea that beacuse of faulty mesurement, it became 1 inch gap between wall and sheve in the upper side. In lower side it is very minimum gap. I stop the carpenters to put the glass door. But now I see that they also make fault in making the doors. The doors are heavier that the shelf. The wooden planks are 1 inch thick while the door are 1.1/2 inch thick. I actually visit few hardwere shops here, but most have no ideas what to do and few says to apply wall putty to fill the gap. But my back wall is coloured (old wall, that why) and wall putty will not set on old wall and timber. I cannot remove it now from the wall otherwise the wall may destroyed. I really need a step by step guide now that what to do after the heves are dry, how to fil the gap and how to put the door without further damaging the shelf.

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?
