Some of the fireplace manufacturer web sites have photo galleries -- you might try them. Here's a link to Fireplace Xtrordinair's. HearthNet.com also has one. Good luck! Here is a link that might be useful: FPX Gallery

Do you have a picture, even if it is from the real estate listing, architect's elevation drawings, or a pic of a similar fireplace? Hang items from the ceiling (you could install a contemporary ceiling mounted picture rail) Source: http://homihomi.com/pretties-christmas-fireplace-wreath-you-must-see/ You could use a stand for stockings https://www.personalizationmall.com/Fleur-De-Lis-Christmas-Stocking-Hanger-Stand-i50055.item?productid=18575&sdest=fprodcat&sdestid=152

Think about furniture placement. You may not want to put the fireplace centered in the middle of the wall, as it appears your furniture won't be able to be centered in front of it. That bump with the 4' opening is for a door, I assume? Where does the door lead? You will need to leave that whole area along the stairs/living room wall open for a walkway (leaving 42-48" open along the wall would be ideal, IMO) to walk through the living room to the door. If you center the fireplace on the wall, the furniture facing it will need to be off center to account for the walkway. The window and door bump outs are going to be awkward to furnish/decorate around, I'm afraid. It looks like the fireplace wall is just under 17', but after accounting for leaving open space for the walkway, that gives you just under 13' wide of space to work with for arranging furniture in the 10' area (the length of wall with the 3 windows) in front of the fireplace. Or are you planning to put your couch/es in the area where the room widens (the second trio of bump out windows)? If so, how are you going to use the ~13x10' area in front of the fireplace?

Definitely need photos. Have you checked that your fireplace will be to code without a stone hearth? Most fireplaces need them...
