Overview
Thornwood Self Storage Development Project
The Thornwood Self Storage development project involves the adaptive reuse of an existing industrial building into a modern self-storage facility. The property, located at 401 Clairmont Ave. off Broadway (NYS Rt. 141), is just off Exit #28 of the Saw Mill River Parkway in Thornwood, Westchester County, New York, approximately 30 miles north of Manhattan. The facility will primarily serve the communities of Chappaqua, Pleasantville, Briarcliff, and Valhalla, in addition to Thornwood. The property has a curb cut onto Broadway (SR 141), which sees a traffic count of 13,000 cars ADT. The Thornwood Self Storage building sits on 0.89 acres of land and will be accessed via a permanent easement Right of Way through the adjacent Safeguard Self Storage property. The gross building area is planned to be 50,500 square feet, with a net rentable square footage (NRSF) of 34,296, containing 371 rental units on three floors, plus a wine storage component and solar roof panels. A demand study indicates only 2.2 square feet of storage space per person within a 3-mile trade area, with an average household income exceeding $150,000. Construction has begun, with an expected completion date of December 17, 2018.
