NORTH DAKOTA — Mercer Mass Timber (MMT) announced the completion of the first phase of construction on the Theodore Roosevelt Presidential Library, a future cultural destination located in the heart of the North Dakota Badlands, and the largest mass timber project in the state to date. Phase one construction began one year ago and is centered on the museum building and its dramatic roof structure of sweeping curves and complex geometry. The roof, designed to echo the rolling topography of the Badlands, required precisely engineered connections and joints, supported by steel wrapped in wood to maintain a seamless timber look. Phase two of construction is scheduled to begin on June 1, with Mercer Mass Timber contributing canopies designed to support photovoltaic panels—enhancing the site’s sustainability and expanding mass timber use in outdoor architectural features.
