Back Facade

When she renovated the 19th-century home last year, Moskovitz added a new back facade, a third floor, a roof terrace and an artist's studio on the basement floor. The home has an angled roof with solar thermal panels (for hot water) and photovoltaic panels (which reduce electricity).

Living Room

The exposed brick is one of the few details remaining from the original structure. Some of the brick was taken from fireplaces, which were removed because of the air they allow into the home. Tighthouse uses 90% less heating energy.


Large windows may not seem conducive to insulation, but the Passive House Planning Package allows owners to assess all design vs. efficiency tradeoffs. Moskovitz used triple-glazed Schuco windows throughout the house.


The stairs were designed to increase natural light, hence the perforated stainless steel treads.

Master Bathroom

All lighting in the home is either LED or fluorescent. Efficient lighting is just one of the many features that cumulatively reduce overall energy expenditure to 75% less than standard homes.

Front Facade

The gray stucco facade is but one of many layers that helps insulate the home. The original row house was built in 1899 and Moskovitz renovated it in 2012
