Would not try to make a 12'x16' room two zones. You should invest in either pull down shades or miniblinds for each window for after dark privacy. Depending upon your child's age, you might have as a birthday activity having each of them paint a plastic suncatcher that they can hang on the windows during the party and then take their own home with them afterward. They're available at big box and dollar stores as a kit with paint included. Make sure the paintbrushes are as well. https://www.google.com/search?q=child%27s+plastic+paintable+suncatcher&source=lnms&tbm=isch&sa=X&ved=0ahUKEwisxp_1h4zdAhWtmOAKHZQGBcgQ_AUICygC&biw=1366&bih=650 Since it's the end of August, you should be able to find summer outdoor furnishings on sale. You might consider investing in a folding table or two and enough chairs to seat as many people as will be at the birthday party -- not necessarily the expensive kind -- in a mix of sizes. If they can be folded or stacked for storing when not in use, that would be a plus. Your small round table could go in a corner for self serving beverages. The art easel, set in a corner opposite the door, could hold a poster with the birthday child's name/welcome message to guests … maybe a picture of a birthday cake. You could leave the cabinets (?overhead kitchen cabinets? for serving buffet style. You might check into purchasing some wheels or legs attachable w/screws to raise the height. Unable to see the overhead light. Before next summer, consider adding a ceiling fan as your overhead light if there isn't one already.

"Can at least put drinks on it" .........why? To heat them up? You're okay with a misplaced light too. Why? Your architect gave you a contract that spelled out the scope of work. If you want more than the scope, you must request and pay, Otherwise?? I'm inclined to say you have a DRAFTSMAN. And video and sound and cable can go ANYWHERE with an IR repeater. They can go a "a half mile" from that tv in a closet.. In a basement.....etc. Virtually everyone is telling you it doesn't look good. ........and It won;t look better "finished". Sorry. You asked.: )

@waverly6 thanks for replying; I would love to see your end product as well. Like you, now I must find a place for the tv (I had a tv easel on that long N wall). I have posted the photos with the new window and the new poll/ dilemma. If you zoom into the new window, you can have a pick at the mountains after the rockwall… And yes, there is a rockwall, and beyond that, about 5ft of leveled ground before going down a sloped hill. So next project will be to lower the rockwall 😉 If you have time come check it out: https://www.houzz.com/discussions/5893846/help-with-sliding-door-coverings-b-w-brown-other.

Congratulations! First and sometimes second homes are often a bit of a compromise between our ideal and our budget. While saving for our first home my husband and I lived in a 600 sf home that housed my husband, me, my 16 year old niece, 3 dogs and 2 cats. My brother had 2 kids and bought a 3 bedroom home. His 6 year old daughter got the master bedroom, 4 year old son got the next room and he and his wife took the smallest bedroom ( 10x12) because it had a door that went out to the back yard and they didn't want the kids somehow going out the door at night or being afraid. Your solution may not be ideal, but there are some great suggestions here for storage solutions. You don't need to keep a ton of clothing hung in your bedroom. Just enough to get you through a week. The other clothing can be stored in another bedroom and switched out when you do laundry over the weekend. The first photo by artistsharonva is a beautiful piece of furniture that would hold everything you need. There is plenty of room to walk around the bed - you only need 3' and lucky you, your bed can actually be placed where there is room to walk around the bed and not stuck in a corner. You don't mention children or other occupants of the house or how you intend to use the other bedrooms. If you do have young children I may not want to be on the opposite side of the house. If you have teenagers you want as much distance as possible - maybe a duplex so you don't have to share space with them. Good luck and enjoy your space.
