American studio The Brooklyn Home Company has designed a Brooklyn townhouse using Passivhaus principles in New York's Carroll Gardens neighbourhood.

The Sackett Street townhouse comprises four storeys as well as a rooftop with views of the Manhattan skyline, along with a basement and a drive-in garage.

Stairs from an outside decking area lead to a back garden, and a private terrace is accessed from the main bedroom.
Passivhaus is a recognised European energy standard for homes that require minimal energy to heat or cool and promote high indoor air quality. The Sackett Street townhouse's back garden
