The ETC's Haven Street space, however, looks nothing like the typical cubicle-filled workplace. Much of the old brick is still exposed on the inside. The vertical wood support beams, relics of the King Cork and Seal Building, weren't covered up during the renovation. And the ceiling ducts are visible, a design aesthetic that gives the Highlandtown office an industrial vibe. The floor plan is completely open — tables surrounded with black, ergonomic desk chairs on wheels are strewn about — although there are several, dedicated office spaces for specific startups lining the walls and separated from center area by sliding pane doors. People, mostly in their 20s and 30s, some in T-shirts and shorts, can be found working on most weekdays, but there are older entrepreneurs in shirts, slacks and blazers as well.
