Since designing the museum’s expansion that opened in 1999, Cornerstone Design has continued to work with the museum on major exhibit projects. The latest and largest of these is an exhibit on the science of construction, housed in a “building in a building” constructed within the museum gallery. The enclosure includes cut-outs showing the various layers of materials in walls and roofs. Planning and fundraising for the exhibit was done by a cross-disciplinary team that included architects, developers, contractors, union representatives, and museum staff.
