Harriett is Hubert Estate’s large modern event space at Coldstream in the Yarra Valley, with polished terrazzo flooring, soaring timber ceilings, panoramic glass and vineyard views. Adjoining courtyards extend the usable experience outdoors, while the room adapts from conferences and brand launches to gala dinners and celebrations. The operator advertises up to 220 seated or 350 cocktail guests, with integrated audiovisual capabilities; a second operator page also describes two bars and a private VIP room. Catering, room setup and access to ancillary spaces should be confirmed for each booking.
