weldwood is located in a rural setting of southwestern dublin, on the south side of old troy road about south of old marlborough road. it is a 1-1/2 story wood frame structure, with a gabled roof, two interior brick chimneys, and a clapboarded exterior. its main facade is five bays wide, with a shed-roof porch extending across it, supported by round columns. above the porch, three gabled dormers project from the main roof line. a secondary entrance is located on the street-facing north facade, sheltered by a gabled portico and topped by a half-round transom window. the building features corner pilasters and other greek revival features, possibly recycled from a farmhouse that previously stood on the property.
