My son used to help me cook in the kitchen - he is 190 cm, I am 175cm. I have an old-fashioned breakfast bar which is raised above the level of the kitchen benchtop. My son would stand at the raised section, I would stand at the lower section, it worked really well. An alternative might be to have a pull out step in the kick board spaces for your wife to stand on - I don't know if it would be high enough, but it might make things more comfortable. Speaking from the point of view of a tall woman, I will have my next kitchen cupboards and laundry raised at least 10 cm to make my life more comfortable - bending forward for any length of time is seriously UN comfortable!

anything is possible depending on budget but you'll need to find examples of suitable sinks (preferably several options with specific installation instructions that can usually be found on brand websites and printed out) then ask a kitchen cabinet maker (who uses Silestone counters) and a plumber to inspect the site and suggest options and quotes

Very true! The five key points stated really can make the difference between going through hell or having an enjoyable experience, which should be had when renovating!

Kate - Whilst I appreciate moving the door would be a great idea, it joins up to our laundry and the door is directly across from the laundry external door that leads to the side garden. I will take photos to show what I mean. Juliahocking - thank you for your suggestions. I am inspired by adding in cupboards/pantry on the opposite wall. Regarding flipping the kitchen 45 degrees, I have added measurements to clarify the space, and if I understand you correctly, there isn't enough room to flip the u-shape (although it is a great idea). I have added another (old) picture that shows the entry door, and next to the entry door is a sideboard/side shelf - this is where our butchers block/island is situated - so gives you an idea of the limited space. Old photo: Entrance door on the left. Next to the door is where the butchers block sits, underneath that painting.
