Building an addition on the roof of an existing building takes a certain degree of expertise and after dozens of successfully completed projects the formula for success becomes simple.
The structure that is added must act in as much an codependent fashion as possible not relying on the existing. New steel joists span across the existing roof to support the new floor its roof and create a new outdoor roof terrace.
Set back from the facade of the existing building beyond the sight lines of pedestrian traffic allowed the addition to be easily approved by the landmarks presentation commission without a public hearing.
Simple design and elegant lines come together to create a modest addition deserving of the building it was placed on.
