A plan to spend nearly a half-million dollars remodeling the interior of the newest state office building in Des Moines is moving forward despite budget cuts that are hitting an array of state programs and services. The Iowa Utilities Board is planning to demolish and redo much of the customer service area in its six-year-old building, adding a conference room and a nicer reception area. Planning documents call for new glass walls and doors, woodwork, paint and even a 75-inch television.
