The Brooklyn Bridge anchorage vault spaces were previously used as storage by the DOT. DSP was hired to design the space for events, art exhibitions and live performances. A custom mix of crushed walnut shells under high water pressure were used to clean the stone yet not damage or impact the integrity of the original mortar. This historic exterior renovation was challenging. The use of neon and special lighting effects give definition and scale to otherwise large, vacuous spaces. The space has public restrooms as well as being ADA accessible.
