    CUPACLAD gave us a surface that was complementary with our modern aesthetics. The surface looks different every time… wet and dry. We have this glistening façade one moment and then a buttery smooth matte exterior, the next. CUPACLAD’s sleek, timeless slate material is certainly turning heads.

    The slate contributed to the overall aesthetic with its modern metallic luster and yet modest-compliment to the historic 1913 Calvary building that sits adjacent to the BSA Leadership Center

    We wanted it to be something like a sundial, so the changes in weather and the movement of the sun can be expressed across the building. The natural slate cladding, with tiny stainless-steel clips catching the light at certain angles, was the perfect solution to express the time of day with shadows.
