While sailing in Boston Harbor last weekend, I was struck by the unusual architecture of the pictured building. The slopes of the facades create an optical illusion suggesting the building is “falling down.” After a little research, I discovered that it is a +100 unit luxury condo. A 3 bedroom, 2,500 sqft floorplan will set you back $8.5M. It is little wonder that Boston was just named the 5th most expensive city in the world to live in.
