Getting a Valuation soon, would this divider classify a 4th bed room?

I’m putting in 4 big doors on a rail system to make bifold doors and seperate the rooms above the step, both rooms are about 9x5m.
I already have 3 bedrooms upstairs, would this classify as a 4th bedroom when the valuation takes place?

Doors are similar to this

Behind were I’m standing is a bathroom/shower/toilet.

 

ive had problems with created bedrooms in the past where a valuer wouldn't classify the new bedroom as a bedroom.

It is depends on the valuer.

Also a way around may be to use a lender that accepts a desktop

 

Not really a bedroom no

And what light/ventilation is there in the new room

 

Light/ventilation? Not sure I understand. There’s doors in each room that access to outside and windows

 

If I used plaster and one door, would that classify as a bedroom? Is there a building code what sets out what a bedroom is or has to be made of?

 

To be classed as a habitable room it needs to have a minimum light and ventilation (ie opening windows).

If you were to build a stud wall with door that would do the job. You would need to build a vestibule to enter the bedroom as you cannot have a door opening directly off a step into a room

 

Thanks Dave,
Was hoping it would work.
You can enter the bedroom via the outside as well, will be interesting to see what the valuer comes back with. I'll dress it up as a bedroom to see if it will pass.
Can an agent legally advertise and sell the house as a 4 bedroom house if I leave the bifold door divider?

 

They could but teh room wouldnt pass standards if your bifolds are on the step level per above re door opening onto a step

 

Are you basing this on the NCC?

 

Thanks Wyllie, it’s only for valuation purposes. House has 2 large living areas even with 4th bedroom.

 

Latest version of the NCC says this about changes in level (there may be other provisions, I've just had a quick look):

3.9.1.6
Thresholds
Where the threshold of a doorway is more than 230 mm above the adjoining surface it must incorporate steps having 3.9.1.2.

I would have the door into the room open into the corridor though - not into the room - or use a sliding door.

 

Sorry not visualising what you mean? Do you mean use a sliding door below the step?

The red circles are indicating where sliding doors lead to the outside in both rooms and I have a staircase indicated in yellow.

 

I thought you were considering putting up a stud wall in the opening following (on top of) the raised section of floor? Another poster mentioned that this would not be acceptable due to the level change in the floor immediately after the door into the new room.

I have provided an excerpt from the NCC and am just suggesting if you were to create a stud wall along the level change it would be better not to have the door into the room swinging out over the level change.

Were you thinking of putting the stud wall somewhere else?

 

Ah ok, nah was hoping to get away with using bifold doors above the step to seperate both rooms and hopefully pass it off as a 4th bedroom come valuation time. It's a come see valuation so can't do desk val. I'll let everyone know how it goes in a months time.
