The Maison East, located at 1438 Third Avenue, is an excellent example of a condominium conversion that has been done just right. With an enviable location in the Upper East Side, this building has beautifully designed apartments that come in 20 unique floor plans. The effects of the conversion can be seen in every room of the apartment: hardwood floors in the living spaces, branded stainless steel appliances in the kitchens and marble features in the bathrooms are just a few examples.
