Summary

Description
In order to make the program come alive and for the 21st Century, our firm:

  • Shored up historic (1883) masonry facades during demolition.
  • Sequenced interior demolition of masonry partitions to create an open atrium that allows natural light from the skylight to cascade down through living areas on all floors terminating at a central courtyard on the first floor.   Structural design also included incorporating an elevator shaft and multiple stairs into the home.
  • Braced the front wall prior to opening it up to accommodate a geothermal drilling rig, which was delivered disassembled.   Our team oversaw its transport through the home, and re-assembly in the rear yard.
  • Drilled of a 1,200’ deep down in a 8” diameter single-borehole.   The standing column well we designed supports a 30-ton HVAC system.
  • Designed ground-source heat pumps were coupled with high efficiency boilers and DHW generators to meet house demand.
  • Plumbing, Sprinkler, & Fire Alarm Systems were provided for comfort and safety of the residents.

We were able to maximize air circulation & provide superior quality indoor air by strategically utilizing the central courtyard and interior balconies- all governed by a custom control and operating logic that we formulated.
