The demolition continues on Caswell Square, this time with the Oral Hygiene building along Dawson Street coming down. By the time you read this, it is most likely gone.
The demolition on the square itself started in March 2020, see this post, and no plans for the land have been announced. If I recall correctly, this is the last building to be removed from the square.
I said it before and I still continue to think that the state government needs to improve the management of their own properties as the loss of these buildings, with private interest in rehabilitation, is a loss for downtown Raleigh.
You can revisit Caswell Square on this December 2016 blog post.
