A floor plan is needed.

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.

Instead of temple with storage, go only for the temple, one open, spacious temple with some glass or any other treatment as per your budget. In the kitchen don't go for the show kitchen thing as you'll be needing dry platform for your gadgets. The sink shouldn't be near the cook top. The offset provided at the end of the main platform isn't correct, instead go for a 27" or 30" platform which is convenient to the cook. In bedrooms, there isn't enough storage. we require dimensions for rest of the layout furniture placement.

The top cabinets above washbasin/sink should be ideally placed at least 90 cms above the countertop. This will prevent the head touching the top cabinet while using the sink. That is the common design principle in Euro/US kitchens.
