At the age of 80 years I am due to have my FIRST EVER brand new, to my design, kitchen installed.
In the past I have always coped, with some tweeks, with the kitchen I have inherited in whatever propery I was living in.
As it is has already taken me close on a year, of looking at units, etc. planning, and organising getting it done, and know that it will be two weeks of total disruption, I cannot imagine anyone wanting to do it every five years. Does, she donate her existing kitchen units etc. to other people???
One of my daughters had her kitchen done (with considerable re-building), very cheaply about fifteen years ago. Took three months of disruption. She is now planning to have it completely re-done in a few months time, more expensively and taking far less time.
