    What's special

    Built in 1886–87 for German immigrant and Galveston merchant Jacob Sonnentheil, this residence is among the island’s most recognizable historic homes. Believed to have been designed by renowned architect Nicholas J. Clayton, it blends Eastlake, Gothic, and Italianate influences with elaborate double galleries and intricate craftsmanship. Extensive exterior work has been completed in recent years, further preserving this landmark property. Planned “from the inside out,” the expansive interior features formal living and dining rooms, a library, breakfast room, spacious bedrooms, five fireplaces, two elevators, hand-cut patterned parquet floors, original plasterwork, rare curly-pine millwork, antique light fixtures, and original stained glass. The detached garage apartment offers two bedrooms, a full bath, kitchen, living area, and gated parking. All within easy walking distance of The Strand and Postoffice Street’s galleries, restaurants, shops, and entertainment.
