Aloha withlove,
1. Not a problem, draw the curtain.
2. Hire a carpenter and...
To keep it simple I'd Activate those directions in the livingroom.
3. I don't know why you're activating the NE - PEN or general space feng shui as showns on P.13 in the Level one course. If it's you romance/relationshi direction hang a double happiness symbol or actvation card on the door.
4. How do you psychologically map the space of each area? Use that.
Much Love,
Shawn
