We are proud to have worked on the Waterfront Station development in Washington, DC. We produced Unfading Green Slate wall panels for the exterior and interior of this impressive building located just half a mile from the National Mall. Architects from Shalom Baranes and representatives from the developers Forest City Washington / Vornado / Charles E. Smith travelled to our factory to select the stone and approve dry layouts for color shades, textures and blending.
