272 West 86th Street is a project where East River Partners purchased three landmarked row houses on the Upper West Side. ERP created plans to combine all three buildings into one, luxury doorman building. The combination of the buildings required preserving the front facade, which is preserved as a landmark but demolishing virtually everything else behind the front facade and building anew. In order to do that, ERP along with its contractor, Ross & Associates, designed a temporary steel bracing system that would support the exterior walls while the remainder of the three buildings were demolished.
In the picture below, you can see that the complicated demolition work has successfully been completed and now the work of building a brand new building behind the front wall may commence.
The construction is more complex than if the building were developed from the ground up since the facade must be carefully preserved and restored.
