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.

Mohammad. I understand your program. You may be lost in the details at the moment. Please do follow and trust the advice given here by all these people. You are about to embark on a reasonably expensive journey. Get professional help with someone who you can sit down at a table and brainstorm with them your ideas and intentions. There are Architects and there are professional building designers who are members of the American Institute of Building Design (AIBD) who are well versed in projects such as yours. I personally love a design challenge. After 38 years designing homes and special use buildings I enjoy this type of challenge the most. I am in Ohio and may not be close to where you are but I am sure with a little investigation you will find the best design professional for you.

Congratulations to all of you. Its a wonderful platform to be on and you all are doing a great Job. My favourite Design Style is 'Minimal'. I just have this strong connection with simple, subtle and elegant things. Cheers:)

Dear Abhay, I am Ravi and I am an Architect. Designing is subjective and collaborative field which relies on many factors like context, location, lifestyle, culture, budget and more. Healthy communication and proper flow of information are quite essential part of any design process which leads us to smart and robust choices. There are infinite possibilities that can be done but to do anything we first must decide what not to do. Elegance in Design always work. As you mentioned above that you want to do a bank design; any Bank's purpose is to serve its users in the best and efficient way with ease. Public trust plays an important rule here. Its a place where processing of the system should be user friendly so when one enter the banks, he/she must feel safe and private. People from all age groups, cultures, classes, professions including physically challenged people come to bank so it is very important to create such an ambience which is barrier free also where one must not feel troubled and where everyone feel united. Easy circulation, comfortable seating, clear signage are few other integral aspects of a Bank Design. Hope I am able explain certain subjective and important aspect of your requirements. If you are looking for professional consultancy, you can share your contact here or can contact me. Thanks and Regards Ar. Ravi Prakash 8882204074
