If you want to remove a building from your portfolio, there are two options. The building can be archived, or it can be deleted.

If the building is archived, all of the information, including marketing material is retained, but the building can't be published unless it is unarchived. It will also not appear in the list of buildings in Findspace unless the user requests that archived buildings appear.

If the building is deleted, it is erased and cannot be retrieved. All information associated with the building is also deleted.
In order to archive or delete the building, once the building is located in the Building View, click on the ellipse(three dots) on the right hand side as shown below. You may need to filter the list of buildings in order to have the building appear by selecting the city, or other criteria to narrow the list of building that appear on the page.
