Accy.
I have read the book and got the tee shirt.
After my wife died I moved from a gaff with 4 beds, 2 1/2 bathrooms, kitchen and utility room to this very errhh compact flat.
Things i did (and should help you) are
1. Seriously de clutter. Get a friend/relative to help as they can be more ruthless than you eg 12 pairs of shoes....really?
2. Get extra sockets by adding to the existing ones. You don't need an electrician, just a handy man.
3. Put a shelf above the work surface, it really helps.
4. I don't have an oven (it won't fit). What i bought were........
A) a 2 draw air fryer. Dead easy. Google will instantly give you cooking times etc. I use mine every day.
B) a Ninja toaster/grill.......I can now do cheese on toast with one utensil

C) a single hob induction cooker plus 3 stacking pans =wok, fryer and 8" pan
D) microwave. Handy for many things in tandem with the air fryer.
Do get help to de clutter.
