I would ordinarily recommend that you don't mix cream/ivory with white as they can often clash, but you have pulled it off with the worktops! bringing in more white in the form of the glossy table will only enhance the look you have already created. the only other option would be a glass table with white chairs or stick with the accent colour of subtle grey for the chairs.

It is a gorgeous room with lovely features. I would second Minnie's colour choices, I have Farrow & Ball Pale Powder in my bedroom and it is a gorgeous colour - like an Eau de nil but changes colour throughout the day and is very soothing. I have dark wooden floors and dark brown leather sofas like you and I think I'm going with Farrow & Ball Borrowed Light when I come to decorate to give everything a lift, a pale rug is also a great idea. The cabinets you mention I would choose white to go with your existing bookcase and also to keep things light against the walls. This is currently my inspirational living room pic, the walls are borrowed light.

My advice is to visit an independent kitchen showroom. Oftentimes they have access to more standard priced options than the big kitchen firms. Reduced height cabinets can be set at almost any height by wall hanging them, or changing the plinth height or having bespoke feet. Since standing is a challenge I presume you will also need to talk to them about pull out units (all of my crockery is in drawers which is much easier to access) you can also put fridges, ovens etc at any height making them easier to access. You might also look at different oven doors, some slide underneath or open to the side making access to the oven easier. You can get dishwashers the size of a single oven which might be easier to load and of course can be set at any height. If your overall strength is compromised you might choose bigger handles to open cabinets. If you want over counter cabinets you might choose to have reduced depth base cabinets to improve access to the cabinets above. You can get extractors that work with a remote control which helps future proof your kitchen if at a later date you find yourself sitting more or unable to stand.

I am putting in a new kitchen in a large open plan room. I wI'll have an island that is 2.4 X 1.1 and will be moles breath colour from farrow and ball and a grey quartz worktop. I am wondering what type of pendant lighting to put over island. I intend to have three pendants but cannot decide what will work. Thanks
