Staunton, much more options. The dining room could be used as a playroom for both younger and older children and is already a room.
We converted a double garage into a playroom/storage room for the children, best thing we ever did but as it was a garage it costs a lot to sort out single skin brickwork, plastering, heating, flooring, electrics, lighting and insulation etc.
The en-suite seems less of a squish in the Staunton one too. Bramhall one the garage is accessed from the outside and there is no possible way to put in a door to access it from the inside unless you lose part of the utility. My FIL's 70s house is like that.
Meaning converting it later isn't really an option.
But Bramhall does have its good points. I always feel that walking from one end of the house to the other with food is a nightmare which you would have to do in the Staunton one. Bramhall's dining room is in the right place.
Can't believe how cheap they are! shock Would buy you a shit one bed flat here if you're lucky!
