A useable kitchen is a must and it is often the details of the design that make the difference. Once the overall working space has been thought through, the fittings become the focus.
Lifemark in New Zealand has partnered with Blum kitchen products and fittings that help make any kitchen more functional regardless of level of capability to open, grasp, or carry things. Drawers instead of cupboards are now standard in kitchen design, but storing items logically and tidily is another matter.
How to make your kitchen more usable covers workspaces and cabinetry, flooring, colour contrasting, taps and handles.
Other ideas
This item from a Todd Brickhouse Associates newsletter includes some good kitchen design ideas. Scrolling down the page, you can see a picture of a pull-out table that nests neatly under the kitchen bench and over the storage drawers when not in use. Colour contrast is mentioned as an important feature. Another idea is a dual height island bench which has multi functional use. The newsletter includes other items that are probably more specific to north America and also some disability specific items.
