Great opportunity to create a penthouse with roof rights, atop a stunning townhouse on the Upper Westside's best block: "The Museum Block" - 78th between Columbus & Amsterdam Avenue. Presently, a partially renovated 1 bedroom plus office floor-thru cooperative, with lot line window, in a 4 unit brownstone. Kitchen and European bathroom needs moderate finishing in this stunning, sunny apartment with decorative fireplace, a cathedral ceiling in the living room and hardwood floors in one of the most charming and upscale townhouse coops in the city. Architect has prepared a suggested floor plan for creating a second level on the roof to include an additional bedroom, bathroom and deck. This is a co-exclusive with Cynthia Crowley at Olshan Realty.
