The Upper East Side’s so-called Bubble House has finally traded hands, and its signature oval windows may not survive the deal.

Property records on StreetEasy show the Edward Durell Stone-remodeled house sold in August 2015 for about $6.85 million. Historical reporting indicates that the exterior is covered by an easement that limits changes, a detail chronicled by Daytonian in Manhattan…
