We are planning an extension and have a choice to extend by 2m or 3m. The 2m extension gives 20x27 kitchen-dining-living room and 53 feet garden. The 3m extension gives 23x27 kitchen-dining-living room and 56 feet garden.
The 20x27 feet room is enough for our requirements, but a 23x27 room has more breathing space and looks better on 3d plan views. I like gardening, but adding a feet doesn't increase the plant beds much, mainly lawn feels bigger.
If you had choice, what would you do?
