The Hancock Street driveway will be closed for the summer starting on Monday, June 25. To access the building you must enter through the Sedge Road driveway and drive along the side of the building by the gym using the access road. You can then park in the front and ring the doorbell at the front entrance. You will have to exit the same way you came in - around the building using the access road and exiting out Sedge Road. We apologize for any inconvenience this may cause.
