where can I see the info? I checked fragments but it doesn't list it there!

You can open the recent season akivements section. In there there is an akivement associated with unlocking the house and if you expand it it has a list of the needed pieces and what you already unlocked.

Journal > Recent Seasons > General > Get Away From It All.

Edit to add:- You need to use the items before they will show up as collected in your achievements.
