The floor collapse at the New Hampshire wedding venue leaves multiple injured and an investigation underway that could reshape how the state regulates historic event spaces for large gatherings.

What Happened at the Preserve at Chocorua
The collapse took place inside a building on the venue’s property known as the Sap House, located at 88 Philbrick Neighborhood Road in Tamworth. At the time the floor gave way, 144 wedding guests were gathered inside for the start of the ceremony. The floor buckled suddenly, creating an opening roughly 20 feet by 20 feet, and sending approximately 70 people — nearly half of everyone present — falling into the basement below.
Several guests became trapped under fallen beams and farm equipment that had been stored in the lower level. Photos released by fire officials show a chandelier and white wedding bunting still hanging from the ceiling above the caved-in floorboards, along with scattered benches that had been arranged for the ceremony just moments before everything gave way.

How Guests and Staff Responded Before Help Arrived
Before emergency responders even reached the scene, venue staff and fellow wedding guests had already sprung into action. They used ladders to help people climb out of the basement and began providing first aid to those with injuries on the spot. Their fast, coordinated response is widely credited with preventing a much worse outcome.
When the Tamworth Fire and Rescue Department arrived, they found an operation already in motion. They took over and continued assisting those still trapped, carefully pulling guests from the collapsed section of the building.
A mass casualty incident was declared given the number of people involved. Multiple fire departments responded to the scene. The Tamworth Police Department asked residents and drivers to avoid the area and find alternate routes as emergency crews worked through the afternoon and into the evening.
Six Hospitalized, No Fatalities Reported
Six adults were transported to area hospitals, all with non-life-threatening injuries. By late Saturday evening, four of those six had already been released. Two remained hospitalized as the investigation continued, with the full extent of injuries still being determined.
There were no fatalities. Fire officials publicly acknowledged that the outcome, while alarming, could have been far worse given the sheer number of people who fell. Officials noted that the immediate response from guests and staff, combined with the swift action of firefighters, made a meaningful difference in keeping the situation from becoming a tragedy.
Overcrowding Suspected as the Primary Cause
The New Hampshire State Fire Marshal’s Office has taken the lead on the investigation. Fire Marshal Sean Toomey stated that while it is too early to draw final conclusions, officials are actively looking at an overloading situation — meaning the building may have held far more people than its floor structure was designed to support.
Investigators indicated they believe the building was over capacity at the time of the collapse. The structure, known as the Sap House, is part of a historic property that dates back to the late 1700s. The exact age of the Sap House itself was not immediately known, but its age is a significant factor as investigators assess the load-bearing capacity of the original construction.
The venue’s own website had previously described the Sap House as a charming New England maple sugar shack ideal for intimate ceremonies, lounge-style events, and indoor-outdoor cocktail hours. That description now sits in stark contrast to the reality of 144 people packed inside at the time of the collapse.
A Broader Safety Question for Historic Venues
This incident is already sparking wider conversations about event safety at rustic and historic venues across the United States. Over the past decade, barn weddings, farm receptions, and celebrations held in preserved historic structures have surged in popularity. They offer atmosphere and charm that modern event halls often cannot match. But that same rustic character can conceal serious structural limitations.
Older agricultural buildings, in particular, were not built with modern occupancy loads in mind. Many were designed to store equipment, shelter animals, or process crops — not to hold more than a hundred people standing and moving together. When these spaces are repurposed as event venues, the gap between their original structural design and current event demands can go unnoticed until something breaks.
In many states, including New Hampshire, regulations governing the conversion of historic agricultural buildings into commercial event spaces can vary widely. Permitting requirements, occupancy limits, and mandatory engineering reviews are not always applied uniformly — especially for venues that have operated for years without incident.
The Investigation Continues
The New Hampshire State Fire Marshal’s Office has stated that its investigation is active and ongoing, with inspectors expected to continue evaluating the structure over the coming weeks. The Tamworth Fire and Rescue Department is working alongside state investigators throughout the process.
The venue, The Preserve at Chocorua, bills itself as a 26-acre retreat featuring a historic farmhouse, barn, carriage house, and cottages. It markets the property as one of the earliest farms in the region to open its doors to guests. Phone calls to the property went unanswered Saturday night.
Tamworth is a small town of roughly 2,800 residents, located about 115 miles north of Concord, New Hampshire, near the border with Maine. The tight-knit community now finds itself at the center of a story that has drawn national attention and could lead to meaningful policy changes for venues like it across the country.
