Built by brick mason Benjamin Franklin Gregg for Oliver and Mary DeMotte. Duplex with independent basement and main unit, 6 bedroom/4 bathroom underwent major remodel in 2019-20 after lengthy permitting process with the city of Boulder, preserving original stone foundation and footprint, exterior lines and features. Only octagon house in Boulder and one of six in the state of Colorado. House was named by the 1st group of CU Boulder students to live there after the remodel, due to unusual semi-circle door and windows and inordinate number of stairs with low headers leading to basement.[ 22]
