Need advice please on splitting a bedroom.

Hi, I'm new on here and hope someone can help me. My son has additional needs and is not able to share a room so we are hoping to split the largest bedroom upstairs (remove built-in wardrobes and large window to replace with two single ones) we cannot convert our garage as we need the storage space and can't afford it. I've attached the floorplan could splitting this room work? How much do you think this might cost? My husband wanted to split both bedrooms so we get four but I don't think that's a good idea.

That is a similar layout to a house we used to own (as a buy to let)  Our next door neighbour did just this.  You obviously need to add an extra window to the front, and then create a lobby to extend the landing a bit to give a door into each bedroom.  Dividing it with a partition wall is the easy bit.

 

When I saw the finished result I was surprised how much the extra lobby took out of the left hand bedroom.  You might explore taking a bite out of the rear bedroom instead to create the lobby to allow all of the front bedroom to become the 2 new bedrooms?

 

Cost wise (this was 10 years ago) I think they said about £10K  It required planning and building control.

What would Kirsty say? But seriously, the cost of fitting out half the garage (leaving front half for storage) wouldn't necessarily be much greater than doing the interior conversion.

Thanks for your help. Wow I was not expecting it to cost that much! Very helpful tho!
