Three-Point perspective is the use of three vanishing points, in this case the third is below the picture so that we are looking down on a building which recedes downwards as well as to the left and right.
I have used Derwent graphic ink pen liners and a water pen to drag the wet ink into shaded areas. I have also used fine nibs in the distance and progressively broader nibs in the foreground.
The deceit of this style that I like is that it mixes rough and clever perspective. The details such as the windows are drawn carelessly to give A loose informal impression, but these components are drawn over a cleverly planned schema to give a sophisticated overall impression of scale and distance.
