In 1869, Thomas Coatsworth purchased a plot of land on the affluent Cottage Street in Buffalo, NY, and he built a large house for his wife, Electa. The mansion, built in the Second Empire style, which is still standing, has an octagonal tower on one corner from which Thomas liked to watch his ships coming into the harbour. The house is built on 8,374 square feet and has 20 rooms with a coat of arms above the entry which was noted to be the banner under which the Coatsworth family served in the War of the Roses.
In 1899, Thomas built a house on the adjacent plot for his daughter which came to be known as The Blue House but it is dwarfed by its neighbour as you can see in the picture above. Thomas only had two daughters, Mally and Jane, and I believe the house was intended for Jane as she was still single at the time. Sadly, Jane died in May 1899 so may have never lived in it.
The Coatsworths eventually moved uptown some time around the turn of the century, and the house began to fall into decline. It was home for a time to the Brothers of Mercy and Carmelite nuns after which it most likely became a rooming house. The house was recently restored and split into ten luxury apartments by developer Noel Sutton.
