Construction of National Schools was regulated by government standard and local communities could apply to the Board of Education for an approved school plan or, as in the case of Gayndah, they could supply their own design for approval in accordance with the following recommendations.
The original school building at Gayndah consisted of a brick schoolroom, 40 feet by 20 feet, with an adjoining infants' classroom 12 feet by 20 feet, under the same roof with a dividing wall towards the southern end.
