Would you prefer a seperate cosy living room and an open plan kitchen dining family space or knock it all out to make one huge space.At teh moment have a kitchen diner with adjoining open plan to small tv area.there is a 14 foot square room next door which I was going to make a cosy adult evening space but it has lovely floor length windows and I think I should just knock it into one.Dp not sure.No toys or anything to consider as ds is 14 and has all his junk elsewhere
