Thanks so much for your reply.

I think the problem with not having the french doors is that at the side there is a big window where alot of the light comes from.. also there is double doors that will fall into the "3rd bedroom" area. so if we made it a room the kitchen wouldnt have much natural light. There is a skylight there but I dont know whether that would be enough. :/

Oh and we'll be fitting a new kitchen
