Hi Ju, I looked at your idea pics and they are all very light and neutral. This room doesn't seem like it is really you. If I am on the right track, I would recommend a colorful area rug, a light colored cover for the sofa bed and a colorful throw over the back. A row of framed prints or photos (18" square or close to that size - not too small) on that wall would give more life to the room as well. Two white filing cabinets could flank your desk along with a sleek white leather/chrome chair. Need to brighten it up!

We have black widows rampant... it takes literally inspecting the wood and having a whisk broom handy to de-bug it before putting it in the canvas sling carrier and bringing it in. I've had to go to splitting my wood up a bit thinner to fire my RMH, that has helped too. Neighbor across chunks up and sells firewood, I can get the smaller diameter stuff he can't normally sell very cheaply off him now to fire with; and he has a splitter and has run some of my old 3/4 cord for me. One sling of wood lasts a good 4x of what it used to, so storing inside isn't nearly the issue it used to be.

Well, for lack of a better idea, since you find it a drafty little space. I'm assuming the draft comes in on the right? Most of the necessities in the area are located of the left side; i.e. vent, thermostat, light switch etc. What I would do I think is caulk up the drafty spots, maybe even add sized poster board wrapped in batting I covered in a gorgeous fuscia with diagonal grosgrain ribbons every which way covered with a heavy velvet to be attached to the area above & below the window. (Of course remove the drapes that are hanging in there). This for the purpose of using it as a pin-it board for notes. Attach a table height board covered in felt to carry across the full width of the little room. Leaving just enough space for a comfortable little antique desk chair. Paint the back wall a bright cobalt blue, paint the ceiling a silvery pearlescent white. Find a way to attach a clip-on task lamp. And stretch a heavy duty enough wire across the top of the opening and complete it with a heavy doubled velvet drape with a drooping valance. Place a swag with fringe & jewels on it to be closed when not in use. Voila intrigue is yours!

Try the TV where the sofa is now and float the sofa perpendicular to the fireplace where you currently have the big chair. Perhaps the big chair can then go where the TV was for a quiet spot for one. Or even better, pull the loveseat off the wall and put the big chair to its left flanking the fireplace.
