At least one first column having a lower portion attached top a first floor and an upper portion attached to a second floor. The upper portion has a bore with an inner dimension. At least one second column having a lower portion and an upper portion attached to a third floor or building top structure. The lower portion has an outer dimension that is substantially the same or slightly less than the first column upper portion inner dimension so that the second column lower portion may be slidingly received in the bore of the first column upper portion in an overlapping, telescopic arrangement. At least one first retainer is attached to the first or second column, the retainer capable of engaging and supporting the second column thereon. The method of construction provides for lifting without the aid of mechanical lifting devices the lightweight columns, lowering each column into the immediately below column to form an overlapping, telescopic portion which braces against bending of the columns, and retaining the columns in place with retainers that do not need to be field bolted or welded thereon.
