Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.

Okay, do you have any theme or colours in mind. Like do you want a modern look, ethnic look or a mix of both. Which colour family earthy tones like reds and browns or Mediterranean like whites, blue and green.

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.

Thanks for both of your responses CUBSpaces team and Shweta from Shades studio. It really gives a clarity about possible consequences. I am now doubt free about changing whole things in Bathroom as it will be interconnected. However will appreciate your opinion on few things: 1. Kitchen wall tiles: I have those from countertop height to roof(almost area of 6X15 feet) which are good and not hollow. I changed countertop 5 years back without any damage to these tiles. It might cost me another 10-15 K, but I feel the whole process and quantity of wasting old good tiles makes me little sad. 2. kitchen countertop: Made new around 5 years back. I don't expect to get it all intact. But large pieces can be cut and can be used as top for other freestanding structures like dishwasher, front load washer, heighten base cabinets, etc. 3. Plywood: I don't mind giving enough labour charges for old sheets recycle. I am planning to use doors, loose sheets(like kept on bed frame of settee frame.) or parts of big frames like settee. I am keen on reducing waste than to save money. You can see various DIY ideas by western people, who remove or sand laminates and re-paint furniture, or carefully remove hollow tiles and re-attach them. Some are also re-painting ceramic tiles. I am just asking myself: Are we creating more and more waste by use and throw approach every 10-15 years, just because we can afford it?
