Creating an Upper Loft (1.5 story) Home

[TheLunas]

Hello,

 

I am trying to create my home I currently live in + am having some issues with the roof + creating a loft (1.5 story home). For some reason, when I create the roof, on one side, it gives two roof edges. I'm not sure why this is and how I can get rid of it. 

 

Loft. Our home is 1.5 stories + has a loft space. I can't seem to create this without adding unnecessary walls. Our loft space follows the roof line. We are in the midst of trying to redo our living room + kitchen, take out stairs, etc which is why I'm trying to do this loft. Photos attached so you can understand! Thank you!!
