Visitors to the world’s leading trade fair for woodworking and wood processing will watch a full-scale residential building rise from foundation slab to topping-out ceremony when LIGNA returns to Hannover from 10 to 14 May 2027, with a wood-frame home built live across all five show days. That is according to Deutsche Messe AG, the fair’s organiser, which will deliver the new LIGNA.Builds format in partnership with holzbau.tech of Rosenheim under scientific oversight from Rosenheim Technical University of Applied Sciences.
“It is precisely this level of integration that makes LIGNA unique worldwide,” Stephanie Wagner, head of LIGNA at Deutsche Messe, said of a project spanning concept development, production planning, industrial prefabrication and on-site assembly. Exhibitors will supply materials and tools and even manufacture individual components on machines inside the exhibition halls, Wagner said, with larger elements trucked to the site overnight for safety and smaller pieces moved live during show hours.
Unlike the demonstration structures trade fairs typically erect, the building taking shape on the open-air site will be a fully functional home with a waiting owner, and once LIGNA closes, crews will dismantle the structure, transport it to its permanent address and reassemble it on the owner’s land. A topping-out ceremony is expected on the Thursday of the show, when the house will be formally handed over to its owner and end customer.
The idea emerged early in planning for LIGNA.27, Wagner said, evolving quickly from an ambitious concept into a clear vision for something every exhibitor and visitor could relate to whilst leaving a lasting legacy. Guided site tours, live assembly demonstrations and topic interviews will run throughout the five days, with the team around Professor Andreas Heinzmann at holzbau.tech leading the build.
Wood Central understands the live site will stand beside the Expo roof, the sweeping timber canopy built for Expo 2000 that remains the world’s largest self-supporting wooden roof at 16,000 square metres. Few venues on earth could hand a timber house a backdrop like it.
Flanking the build are two supporting formats, with the LIGNA.Builds Village, presenting technology providers and service companies in compact nine-square-metre wooden pavilions, and LIGNA.TruckStop is returning for a second edition after its 2025 debut. Aimed squarely at the skilled trades, the TruckStop will feature manufacturers demonstrating power tools, hardware, fastening technology, and wood-based materials directly from show trucks and vans.
The live build follows the fair’s post-pandemic rebound, which drew 80,000 attendees from 160 countries in 2023 before LIGNA 2025 attracted 78,000 professionals from 156 countries and 1,400 exhibiting companies from 49 nations. Timber construction has become one of the fair’s defining themes, with short construction timelines, high prefabrication rates and digital manufacturing filling the order books of the machinery makers that dominate the Hannover halls.
Demand for space suggests the industry has already voted, with Deutsche Messe confirming in February that more than 80 per cent of LIGNA 2027’s exhibition floor was allocated fifteen months from opening day and every leading company in the sector registered to attend.
