A barn raised on the grounds of Gladstone's Atkins-Johnson Farm and Museum has reopened as a $3.5 million, 7,300-square-foot event hall that can seat around 200 wedding guests, replacing a deteriorating structure that was torn down to make way for it. The new AJ Barn opened last month, and it will host its first wedding reception later this September.
The project traces back to planning that began in 2023, with construction starting in July 2025, according to The Kansas City Star. The new barn was built by Centric, a Kansas City-based builder, and was funded largely through Certificates of Participation, a municipal financing tool the Gladstone City Council formally approved at $2 million for the event facility and barn replacement back in April 2024, according to City of Gladstone council records. The city owns both the new barn and the rest of the surrounding property.
Even as the old barn came down, the museum held onto pieces of its past: the original cupola now sits atop the new structure's roof, and other materials and artifacts from the old barn were preserved, the Star's report notes. Mika Schrader said the revitalization restored a deteriorated part of the property, and separately reflected on the site's deeper history, saying that continuing family memories and relationships more than 200 years later is special.
What's Inside the New Event Hall
The barn includes a kitchen, two bridal suites, a sound system, and optional open-air full-length windows, per the same account. Wedding packages include 12 hours of rental time along with planning consultation, tables and chairs, event setup and tear down, on-site support staff, and property use for engagement photos. Packages start at $4,500 during peak wedding season from April through October, dropping to $4,000 from November through March.
Demand has already stretched years out, with the venue receiving rental inquiries for events through 2028. Beyond weddings, the AJ Barn has already scheduled a Scouting America event and a graduation party, and museum leaders say the space will also host museum-related events and educational opportunities. Linda Borders said the venue is a great asset for the city and community.
Rooted in a Two-Decade Preservation Effort
The barn is the latest chapter in a much older story. The City of Gladstone acquired the historic farmhouse and its two-acre property from owner Lena Johnson back in 2005, stepping in to save the structure from demolition after it racked up code violations, according to the Friends of the Atkins-Johnson Farm. The farmhouse itself began as a log cabin built between 1831 and 1834 before Jonathan Q. Atkins expanded it into a four-room I-house in 1853, making it one of the oldest continuously occupied residences in Clay County across 155 years of private family ownership, per The Historical Marker Database. The property earned a spot on the National Register of Historic Places on November 4, 2007.
The National Park Service describes the federal Historic Preservation Tax Incentives program as a way to leverage private investment in the adaptive reuse and preservation of historic properties.
Gladstone later expanded the footprint in 2009 by acquiring the adjacent, abandoned Big Shoal Cemetery through the Missouri Attorney General's office — an 1824 burial ground holding 165 marked and unmarked graves, including veterans of the War of 1812, the Black Hawk War, and the Civil War, according to the Atkins-Johnson Farm and Museum. The farmhouse finally opened to the public as a restored museum and educational farm on April 27, 2013, following years of municipal and volunteer restoration. Today the full complex spans 22 acres within Gladstone's Big Shoal Heritage Area, incorporating heirloom vegetable gardens, walking trails, beehives, and preserved outbuildings alongside the new event space, according to Shape Architecture Studio.
Timber Frame Design and What's Next
Architectural plans from Shape Architecture Studio describe the AJ Barn as a prefabricated timber post-and-beam structure manufactured by Legacy Post & Beam, anchored by a 3,600-square-foot main great room with 16-foot sliding glass doors opening onto views of the surrounding meadow. The farm also plans to construct an outdoor ceremony space with a pergola, with that addition expected this October, per the Star's reporting.
Revenue from the new event bookings is expected to support future museum operations and ongoing needs, easing the financial pressure of maintaining the historic site. The museum also grows corn, pumpkins and sunflowers, which are sold at various events on the property, and it hosts a free annual Big Shoal Farm Sunflower Field Festival on a seven-acre sunflower field, according to Kansas City on the Cheap. To mark the barn's debut, the museum is also running a special exhibition called “Lace, Laugh, Love: Wedding History in Missouri,” on view from July 8 through October 3, 2026, showcasing 200 years of regional wedding artifacts.
According to U.S. Census Bureau QuickFacts, Gladstone's median household income was $79,271 in 2020-2024.
