The Lower East Side’s hip movie house, the Landmark Sunshine Cinema, will close when its lease expires in January 2018, The Post has learned.

The 30,000-square-foot building at 139 E. Houston St. has been sold for $31.5 million to developers East End Capital and K Property Group, which will convert it to a mixed-use development with retail and upstairs office space. The site includes 20,000 square feet of air rights.
