Good evening,

We are planning to purchase a 3 floor house. As I understand the doors between the stairwell and habitable rooms have to be (FD30) fire doors.
As per the floor plan attached (I hope I was able to attach) on the 1st floow there are 2 fire doors, one between the kitchen and stairwell and another one between the living room and stairwell. We would like to move the door 2 to be door 3 (i.e. we will terminate door 2, to wall in and make a new door), and the door 3 will be a double fire door. This way there will be still firedoor between the stairwell and living room but on a different place.

My question is if it can be done please? Obviosuly we have to call a structural engineer too to make some calculation but from building control perspective is it possible please?

I've exchanged some email with the local building control expert but he hasn't replied yet what I have to do to get an official confirmation.
Could anybody please help me?

Thanks a lot!

Apologies, for some reason I can't upload image.
However hopefully the floor plan can be viewed on https://drive.google.com/file/d/1E981QWdgOn_PY3Bu3oey2ieaWBQIexPZ/view?usp=sharing

As you say, the requirement for this type of house is that the staircase must be protected to facilitate safe use in a fire. The existing doors, as described, should be suitable for this purpose and the proposed alterations should maintain that level of protection. 

Building Control may require evidence that the alterations do indeed maintain the required level of fire protection.

Thank you, Neil for the reply!
I presume I will need a confirmation from Building Control before the alteration that they are happy with the proposed solution. Does it mean that I have to apply for a property visit from Building Control when I can explain what the change will be please?
Or what can I do please to prevent a shock when the builder completed the job (moved the door and changed the single fire door to a double fire door) but Building Control would say that 'it is not correct like that, please change it back'?

Thank you very much for your help!

Best to contact your local Building Control office for advice. My experience, having received different comments from different LBC offices.
