If you absolutely MUST be mobile, there are electronic "pianos" that are lightweight and very portable. The sad thing: they have to be plugged into electricity. The happy thing: they never need tuning. One of my schools has a Yamaha Clavinova, 88 key - plays like a piano except that you plug it in. This even looks like a modern basic piano - no ugly ironing board type stands for this! Yamaha and Kawai both make these, and some of them are lovely pieces of furniture but they don't weigh what a real piano does! My other school has a baby grand that they used to mistreat. I told them several times: you need to move it away from the doorway, it's not meant to sit in front of a door that is constantly open. The church that uses the Multi-purpose room complained that it was always out of tune. Finally, the district moved it to the stage. I can't use it for music classes up there, so I have one of those little portable Yamaha's that take up space on top of an empty student desk. But it serves the purpose! Jaybird, I hear ya on how much music. Mine is in the shelving under the stairs AND in two crates in the storage room, and some went to college with my daughter (never to be seen by my eyes again, probably - but no matter). DonnaR/CA

We solved the problem by hiring piano movers to take the baby grand piano apart and stash it in the kitchen (on its side), well covered with a plastic tarp to protect against all the dust. Other movers moved all the furniture out of the living room and dining room into the garage. The contractor we hired removed the carpet everywhere from the ground floor and the stairs to the basement. Since we discovered hardwood parquetry underneath, we opted to have it refinished (sanded, stained and varnished). After the cleanup, the piano movers came back and moved and reassembled the piano in the living room while the other movers moved all he furniture back upstairs from the garage. This first phase lasted about a week and we had to move out of the house for that duration, including the 2 cats. Then the basement carpet was removed and new engineered wood floors were installed there, along with other renovations to remove ugly (fake) wood paneling from the walls and replacing fluorescent lighting with some pot lights, a couple of weeks later. This second phase took about 2 weeks including painting of basement and stairway walls and cleanup. All this time we kept the piano covered in a plastic tarp and had a plastic tarp hung over the access to the basement to prevent the dust from spreading to the upstairs and the cats from getting in there. 5 weeks of disruption altogether, but with very nice results in the end. The next phase will involve removing/replacing the moldings and all the ceiling light fixtures (getting rid of the blasted ceiling fans everywhere LOL) and then painting all the upstairs walls and ceilings. Maybe in the spring when we can keep windows open. We are kind of fed up with all the disruption plus we need to find just the right light fixtures.

If this space does not need to be a tv room, I would take the opportunity to create a music/library space. Do a wall of built in bookshelves where the accent wall is and get four super comfy club chairs in either leather or velvet, a couple of ottomans, and a couple of end tables. You could group all four together in the middle of the space, or do two groupings, one closer to the piano.

@Tootsie: The fireplace is non-working/covered, so there's no issue there. It is visually the focal point of the room, though.
