I have just signed the contract for a house with not the best layout. The issue has arisen from the owners filling the side veranda in. This has left the bathroom and a bedroom windows opening into another bedroom. I have proposed closing in both windows, and then having a windowless bathroom and bedroom. Not sure if there are some building regulations I need to be aware of before I close them in. I was then thinking of installing a good extraction fan in the bathroom, and the bedroom door opens into a hallway with a window- may get ventilation from there. Another idea is to move the walls for both small bedrooms (only single bed can fit in) to make them maybe a double hopefully and then the study in the middle with the bedroom window still opening into there.
This house is proposed to be a rental. Any suggestions will be greatly appreciated!
