Dome is a free standing, open air, eight-lobed—or octofoil—dome. Rather than using pendentives or squniches, which
support a dome by resting on perimeter columns or walls, Confluence Dome’s octofoil
geometry permits an intermediate structural system allowing for an open
interior volume and a free perimeter.
Eight structural cores circumscribe the central volume, supporting viewing
platforms and the dome’s shell.
Dome has four public levels. The
Under Dome is divided into a grassy pyramid’s four sides housing ticketing, a
café, gift shop, gallery, and public restrooms. The Belvedere, 30’-0” above
ground, is an idyllic platform at the center of the dome accessed from the
grassy pyramid. Before reaching the Sky View, 126’-6” above ground, elevators
drop visitors off at the Procession Level, 100’-0” above ground. The final 26.5
foot ascent unfurls along a gently sloping helical ramp cutting through the
dome’s inner mass. As
visitors ascend, they encounter four portals overlooking the landscape below. This
procession heightens anticipation while creating a utility space below The Sky
View where the elevator lift houses are contained. The Sky View level reveals panoramic views with a 47’-0” diameter oculus framing the sky above.
