Husband working from home

I’m posting in the rant room because I just need to vent before I explode! Since March of 2020, my husband has been working from home. We are fortunate to have a fourth bedroom which we converted into an office for him. We have a 3yo and 9mo. I’m home for the summer, as I am a teacher. He is driving me NUTS working from home. He’s constantly asking us what we’re doing, if we’re going anywhere. If one of the kids is crying, he comes down to see what happened. He’ll come downstairs to chat here and there, but if the girls get upset he disappears immediately. I take the girls out of the house at least once a day whether it’s to my moms, one of my grandparents, the park, friends, library, etc. But, I have had 0 alone time in my own home since March of 2020. Another thing is he will find time in the day to get stuff done...mow the lawn, run to Home Depot, etc (all on his lunch time not company time). But if I have to do something to do (like a dr appt), he suddenly needs to work through lunch. I’m just totally over it.
