OK, I was drawn in by the picture of Austin Nichols & Co. (184 Kent).
But Suzanne Spellen (Montrose Morris, from Brownstoner) has been posting on Substack for over half a year now. She still posts about Brooklyn (see link above), though much of her focus has shifted to Troy, NY, which is also fertile grounds for architecture history. Her research and writing is always top notch, and the Substack is worth checking out.
