Moving into a house where the ground floor has an open space layout and some quirks due to it being an old victorian house. Photo 1 (a very rough mockup) shows what each element in the picture is and some measurements. We have a baby grand piano that needs to be placed somewhere and a bit confused which layout would work best. Photos 2, 3 and 4 show possible options but open to other suggestions.

The only thing I do not want to do is use the skylight room for the piano as it has a lot of light and is a new extension and then that room would only be used for playing if we place the piano there.

I am leaning towards making the skylight room as a living room though it might be slightly tight - although in length it is slightly longer, it is limited by its width and the awkward corridor next to the kitchen.
