What REBUILD does

REBUILD is an annual B2B trade exhibition and congress organized by Next Business Exhibitions S.L. (Nebext), a privately held Spanish company registered in Madrid. The event is positioned as the leading innovation event for off-site construction, digitalization, and sustainability in Spain, and is held at IFEMA Madrid, with the 2026 edition running March 24-26, 2026 and the next edition confirmed for March 16-18, 2027. REBUILD 2026 attracted 32,487 construction professionals, 758 exhibiting companies showcasing 2,417 solutions, and 732 expert speakers across 363 congress sessions.

The core offering combines a physical Innovation Showroom with an Advanced Architecture and Construction 4.0 Congress featuring 8 simultaneous auditoriums and sector-specific forums covering off-site construction, BIM, AI, digital twins, sustainable materials, decarbonization, and smart buildings. Specialized programs include the Contech Startup Forum, Advanced Architecture Awards, Talent Marketplace, One-to-One Speed Meetings, and multiple construction challenges. The technical infrastructure supporting the event comprises a registration and ticketing system, the REBUILD Mobile Application for attendees, and a post-event Video On Demand platform.

REBUILD's business model is event-cycle driven, monetizing through three primary streams: exhibitor and booth fees structured as Partner, Exhibitor, and Newcomer participation packages; congress and visitor passes (Business Pass, Premium VIP Pass, Virtual Pass at €60 for recorded sessions); and sponsorship and partnership contracts across Global, Event, and Institutional tiers. The customer base spans developers, architects, builders, engineers, installers, and rehabilitation companies across Spain and Southern Europe, with major partners including Holcim, Saint-Gobain, Deloitte, AEDAS Homes, and institutional endorsements from MIVAU and the Comunidad de Madrid. A parallel REBUILD Rimini event in Italy signals an emerging international expansion strategy.
