Damn right, we have a path each between each house, 1 slab width maybe 2 foot plus gravel edges of 6 inches either side of the slab... 3 feet - ish!
No windows on the upstairs at the sides tho, just 1 on the ground floor in the laundry, so no need for ladders etc and thankfully no wood to paint or no uPVC needed there either.
Bless the developers for being so thoughtful!!
Mind you, its a 4 bed detached with garage, laundry and the back garden lengths are good at 60 feet, all for £60k 10 years ago so I though "what the hell"!
