I am not in the UK. We are a family of four and we live in a 3 bedroom bungalow in the med. My dc are a boy and a girl who are preschool age. We have frequent visitors. When people stay the dc share a room. The bungalow is a strange layout. The kitchen is at one end of the house and then a lounge diner at the opposite end. Two of the bedrooms are off the kitchen and both the kitchen and master bedroom open out on to the garden.
The kitchen is quite large and we don't use it very often and it currently has no seating at all. We had a breakfast bar but the stools were uncomfortable and I didn't like looking at the wall.
I have space for either a sofa, or an island or a nice table and chairs but I can't decide which. I wondered about a sofa bed but is it odd to put up guests in the kitchen? And DH can't get his head around a sofa in the kitchen. We both want the room to be more like the heart of the home like it is in most houses and don't want to spend too much.
