To say this is reasonable?

[RhythmAndBlues64]

To say that if you live with adult kids, it's still my house my rules?
I want to set up an office for DP. It will be in the bedroom my son has just vacated. DP will be taking a lot of zoom calls in there. It is directly opposite my daughters room.
Adult DD seems fed up about it. She is often here during the week as works alternate days which can fall on a weekend.
She is saving hard to move out so I can sympathise but it's still what we want to do.

Yanbu

I'm not really sure I understand what her issue is? Can't she and your DH both just shut the doors to the rooms they are in?
What is the difference between your DH using the room and your son using the room? She's being a bit precious I think OP, sorry.

The noise does carry and DP does have a loud booming voice so I sort of get it. She hasn't said anything but I know her well enough to know she isn't happy about it.
My son was barely at home to be honest as was always at his partners.

I wouldn’t worry about this. It’s a her problem

So she needs to suck it up!!!

I think "my house my rules" every time would probably be too rigid and lead to resentment, but you're not unreasonable on this one, at all. Get her some noise cancelling headphones for Christmas.

I wouldn’t be happy with her attitude!! He’s working not partying. In his own house. If she doesn’t like it she should leave quicker.

I work on the principle that I pay the mortgage and the bills, and that whilst you are very welcome to live here as an adult child, if you don't like the conditions then feel absolutely free to move out, pay for the roof over your own head and swing naked from the chandeliers if you so wish.

He's working and so she'll need to accept that.

Is your DP her bio dad?

Once my kids became adults l always said " it's your house too".
No l don't believe in rules like what you suggest

Working from home trumps wanting peace and quiet. One earns the household money, the other doesn't. Suck it up buttercup. Go to a different place to chill, put headphones on, go out.

Can you just tell she's unhappy about it or is she letting you know passively aggressively?
As much as you have the right to do what you want with the room, you can't police her feelings about it. Maybe the noise is bothering her but she hasn't said anything because she respects that it's your house?

@RhythmAndBlues64

youre not living with adult children, they're living with you!

how long has DP been on the scene?

where is he working from now?

is there any other option?

Is your DP her dad?

Honestly a "big booming voice" can be such a PITA, especially if it stops her being able to enjoy / relax in her bedroom, which should be a nice space she can chill in.

I hate the 'my house, my rules' line to your own children. If your partner needs an office then he needs an office, but there's no need to be all 'my house, my rules' when your daughter hasn't even said anything. It's not nice if you can't get peace in your own bedroom and it sounds like she's doing well, saving hard and not complaining anyway.

Tell your partner to be quieter. No one has to be loud.

Agreed. Being loud is annoying.

Eh? She's not happy but is respecting your decision and not saying anything, surely that's enough? What are you expecting her to do, change her feelings or just hide them better?

"My house my rules" suggests that you think she's not following your rules. If your rules are "pretend to be happy at everything regardless of whether you actually are" then yes, that's unreasonable. If your rules are "let me do what I want" then surely she's already following them...

How long has he been living there? Is it possible she feels like she's being pushed aside in favour of him?

We never married but he is her father.

Does he have to “boom”?

Tbf I have dh working at home downstairs in the study, but there is no door, and his calls are loud and very annoying. I can ignore them most of the time because if I'm downstairs then I'm busy, but if I'm trying to think or do something quiet they grate very quickly.
On the very odd occasion I've still been asleep when he's started work, his first thing in the morning meeting always wakes me and that's not next door.
He's normally softly spoken, fine on the phone, but put him on a Zoom call and he shouts and over the call they seem to get louder and louder.

So I have a lot of sympathy with your dd.
I work full time out of the house, so I get maximum an hour or two when I get back if he's working late, but that is enough for me.

Has he got a headset -might be an idea

You can set up an office in any vacant bedroom in your home. It's not like your kicking her out her room to accommodate the office.
Surely he just keeps the door shut.
If she works nights for example, I can see it could be a little disruptive though. But it is your house and she needs to compromise a bit. He could also make an effort not to be unnecessarily noisy.
It's great she's saving money to move out soon.

Sounds like it’s OP’s house.

DO should make an effort to keep his voice down. There’s no need to shout. That’s what the microphone is for.
