After hiring Oasis Design Group to develop their 2010 Garden Master Plan, Birmingham Botanical Gardens will work once again with Oasis to complete a redesign and expansion of the Upper Plaza entrance area. The Upper Plaza is a transition space between several garden areas and serves as an important part of the Gardens' entry experience. Oasis' redesign of the Upper Plaza provides for an expanded Gardens Café outdoor dining area and an adjacent upper plaza to accommodate special events. The design improves drainage by directing surface runoff into an on-site swamp, provides barrier-free accessibility; improves pedestrian circulation; and creates better visual connections between the adjacent garden spaces.
