A century-old residence in Oneco, Florida, has achieved a significant milestone in local heritage preservation. The
The house, which was previously listed on the National Register of Historic Places, is noted for its rare architectural style in the region. Designed in the Richardsonian Romanesque Revival tradition, the building features substantial masonry, arched openings, and a level of structural detail that remains largely unchanged since its construction. According to local officials, while the county established its historic designation process over a decade ago, the Johnson Helm House is the first property to successfully complete the requirements for this local status.
A Legacy of Preservation
The landmark status serves as a testament to the dedication of Margi and Pat Nanney, who have owned and maintained the property for 41 years. Since moving into the home in 1985, the couple has focused on conservation rather than modernization, estimating that approximately 95 percent of the house remains in its original state. Key features, including the original woodwork, windows, flooring, and a staircase adorned with hand-carved newel posts, have been meticulously preserved throughout their tenure.
Beyond its architectural value, the home has served as a private residence for the Nanneys, who raised their children within its walls. The couple has actively curated the history of the house, collecting archival photographs and connecting with descendants of the original owners, Johnson and Fannie Helm. These efforts have transformed the property into a living record of the Oneco community, which has deep roots in Florida’s agricultural and citrus-growing history.
Future Protection and Public Significance
The new local designation introduces a formal review process for any future modifications to the property, ensuring that its historic character is safeguarded against significant alterations. Commissioner Amanda Ballard noted that this designation is a landmark achievement for the county’s preservation efforts, setting a precedent for how historic structures can be integrated into modern life while maintaining their original identity.
For the Nanneys, the official recognition is a meaningful conclusion to four decades of stewardship. By securing the home’s status, they aim to ensure that the building’s connection to the early 20th century remains intact for future generations. As the house enters this new chapter, the owners have expressed interest in potentially increasing public access to the site, allowing the community to engage with a rare, well-preserved piece of local history that has successfully weathered the rapid development of the surrounding Suncoast region.
