which doors do I keep when I knock through?

[lulubop1]

I have a 3 bed semi. I'm planning on knocking through to my kitchen and also knocking down the wall between the lounge and dining room. I want the front room to become the lounge and the back room to be through from the kitchen. The front room is currently the smaller of the rooms but I want it to become the bigger section of the whole open plan. however, I'm unsure which doors to keep and which to close. Can I keep just the middle door or do I need to have 2 separate entrances.

We kept all our doors when we did this. The living and dining room doors lead onto the hall. The kitchen door led onto the end of a corridor and we made it into a cupboard.

open plan loses more heat. If you are open to the staircase the warm air will all rush upstairs.

if the cooking area is open plan, the cooking smells will spread.

you need to keep the stairs safe with a door - ideally a fire door - as this may be your only means of escape from upstairs in the event of a fire !
