building made the Gardens a year-round facility with an indoor plant conservatory, a butterfly glasshouse "wing," an auditorium for classes and events, a gift shop, a cafe, an events hallway, greenhouses, a head house, staff offices, and two large areas housing all the heating and cooling and greenhouse systems equipment. In 2008, a construction project renovated major sections of the Conservatory Complex. The old gift shop and cafe space was converted into a meeting space and became known as The Garden Room. The gift shop moved into a space next to the lobby, replacing the auditorium. The Maintenance Building was constructed just north of the Conservatory Complex, in between Jack Trice Stadium and the Gardens. Architects Smith Metzger designed the Christina Reiman Butterfly Wing, the Mahlstede Learning Center, Conservatory Complex and Marge Hunziker House. In 2017, Reiman Gardens gained a new entrance sign by University Boulevard. This sign, a long wall with high letters, has a garden bed surrounding it that is maintained by the Gardens. The Joey and Jesse's Herb Garden had its raised beds reconstructed. In 2018, the Hillside Water-Wise Garden opened, the first project completed of the 20-year Master Plan that was released to the public in January 2016. In summer 2018, the DeeAnn Drew Shade Garden opened. In 2019, the Pattern Garden was resurfaced; the Reflection Garden pergola, the Sunny Side Yard trellises, and the fence around the Marge Hunziker House were replaced; and many gravel paths throughout the Gardens were converted to concrete. A mobile and modular insect display was created for the Gardens' lobby with funds from Alliant Energy, allowing the Gardens to display new insects and invertebrates acquired in 2018, 2019, and 2020. In 2020, the front entrance to Reiman Gardens had its walkway repaved and the wooden trellis structure was replaced. Elwood the World's Largest Concrete Gnome had new stairs with a railing installed thanks to a donation from John and Linda Schuh. A pergola was installed at the top of the Hillside Water-Wise Garden thanks to a donation from Joyce and Bud Nichol. More gravel pathways throughout the Gardens were converted to concrete. In 2021, the Sycamore Falls garden space opened after 5 years of construction. This was the second project completed of the 2016 20-year Master Plan.
