Minimum Room Size for a Yamaha u1 or u3

[calca]

Hi there, just registered and this is my first post. Just a quick question about the minimum room size for a u1 or u3.

I have two children and am planning to have the elder one start to learn to play piano in 2 years when she's 5-6 years old. I know nothing about piano but I'm a classical music lover and planning to learn piano together with my elder one.

I'm looking at purchasing a u1 or u3. We have a den on the main floor, in a corner position. The size of the den is 10'2'' x 10'10'' x 9'(H), with hardwood floor, a mid-size window and a 5' opening to the hallway. Virtually nothing is put in there now as we just moved into this house. I hope to put the u1/u3 in there in the future. I wish to install a two-panel door (similar to this style: https://media-s3.viva-images.com/vivastreet_gb/clad/5b/3/60767583/large/1.jpg)  to the opening so I can enclose the room when someone is playing. That way both the player and other family members won't be disturbed, especially for the younger one.

However I was told not to install a door there because if the room's too small and enclosed the piano won't sound good or the player will feel uncomfortable blah blah... Anyone can give me an idea if I should put a door there or not? What's a minimum space size for a u1/ u3 from the acoustics perspective.

In my opinion, that room is quite adequate for either of those instruments -- and I don't think that adding a door would be a bad idea at all.  If I may suggest it, I would place the piano so that, if the door is open, the player can at least glance through the door -- but that's a personal preference.

I would also seriously consider an area rug, assuming that there is a hard floor -- wood, tile, what have you.  I might also consider placing a tapestry or other fairly heavy hanging on one of the walls.

I might also add that you are going to hear that piano elsewhere in the house!

As to the player feeling uncomfortable with the door open or closed or what have you, that depends on how the others in the house treat the player, not on the presence or absence of a door.
