ICA was retained to design and restoration of the historical 1930 Thordarson Estate Boat House located at Rock Island State Park. This iconic structure was in need of significant exterior repairs across multiple parts of the building. The exterior renovation preserved the historic structure from further deterioration. The Boat House is subject to treacherous weather conditions on the island within Lake Michigan. The project consisted of restoration and/or replacement of all windows and doors, sills and aprons, abatement of all remaining lead paint, repointing and repair of exterior masonry, and assessment and repair of the interior chimney.
