KG+D Architects Vice President Erik Kaeyer unveiled concept designs of the proposed Hindley, Royle and Holmes elementary school additions at a Board of Education meeting last month. The designs were unanimously approved by the Board of Education. The estimated construction budget for all three schools is a little over $68 million, with base bids coming just under budget, officials said. All three buildings were last updated in the late 1990s. All three designs have been presented to the Architectural Review Board and are expected to enter Planning and Zoning hearings toward the end of November.
