Fairylea that's amazing - you are lucky!
We are both around 60. We witnessed PIL struggling in a house that was no longer suitable, long after they were able to look after it or willing to move. We now have to deal with decades of stuff in the house (FIL died last year, MIL now in a care home).
Meantime, our DCs are gone, so we have 2 bedrooms too many (make that 3...), the front room gets used once in a blue moon and the dining room likewise. It's too big. But we both still work full time. Our plan is to downsize to a newer, possibly new build house which won' need the maintenance this house needs (1950s build).
I'm enjoying designing it in my head!
Large roomy kitchen, but few (if any) high cupboards
Utility room off kitchen
Small TV lounge
Smaller, cosy room (or corner) just for me, for reading / glass of wine / bit of sewing or knitting
An 'occasion' room for when guests come probably never
2 bedrooms
A decent sized craft room for me, so I can spread out!
It will have wide doors, a wet room etc so that it will still work when we are old and infirm.
It will be all on one level, except that DH will have the whole of the attic for his model rail layouts. I'll let him have a loo up there on condition he cleans it himself
