I had purchased hafele hob 10 months back... I got it serviced 6 times... Now i requested for replacement with new one... Still they have not attended my request...

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.

Concrete gives more premium look i feel if i consider it for a long span of time... Steel will cost alot and plus it will require maintenance. Any guesses how can cost effective moulds can be created of such shape if we wana do it with concrete?

Hello there, You need to consult with a local architect first for the layout and plan approval. They will provide you with floor plan and furniture layout, 3D elevations etc. Also, they would send them for approvals. What you're asking for is a paid professional service. Please consult locally first. Else, if you need anything specific, please feel free to connect with us. Also, your budget is too tight for 800 sqft unless it is an open plan. Cost of construction starts from 1100-2000/ sqft depending on materials and contractor. Usually that will cover design and approvals costing as well. Regards, Aurum Ideas and Spaces Bhubaneswar
