Architectural Building Week Sofia

Architectural Building Week is Bulgaria’s leading international trade fair for architecture, construction and real estate development. Each year, industry professionals gather at the Inter Expo Center (IEC) in Sofia – the country’s most advanced exhibition and conference venue. Organised by the IEC itself, the event positions the centre as a key driver of regional development in both the built environment and the wider economy.

Far more than a conventional product showcase, Architectural Building Week serves as the premier platform for knowledge-sharing, innovation and emerging trends across Southeast Europe. Its broad thematic scope spans the entire construction lifecycle – from planning, design and structural engineering to interior finishing, building services, landscape architecture and industrial facilities. Core themes include innovative materials, BIM technologies, sustainable construction, smart home solutions and the ongoing digital transformation of the sector. Exhibitors present practical, market-ready solutions to current industry challenges – from cutting-edge machinery and construction materials to software for intelligent building automation.

The event is closely aligned with Sofia’s dynamic urban development. In recent years, the Bulgarian capital has emerged as a hub for architectural innovation and urban regeneration. Architectural Building Week reflects this transformation, providing a platform for both domestic and international stakeholders to showcase ideas, launch projects and forge new partnerships. A comprehensive programme of high-level conferences and seminars reinforces the fair’s role as a trend barometer, covering topics such as accessible design, energy efficiency and future technologies.

A particular highlight is the annual awards ceremony hosted by the Bulgarian Association of Landscape Architects, recognising outstanding achievements in landscape and open space planning. Live demonstrations and product presentations further enhance the visitor experience, fostering direct exchange between manufacturers and end users.

Exhibitors represent a broad cross-section of the industry – from building materials and machinery manufacturers to software developers, energy providers, architectural practices, urban planners and landscape architects. The event attracts a professional audience that includes architects, civil engineers, project developers, investors, contractors, public officials and decision-makers from construction and real estate companies.

Conveniently located next to a metro station and easily accessible from both the airport and the city centre, the Inter Expo Center offers state-of-the-art exhibition halls, conference facilities and digital infrastructure – the ideal setting for an event that not only reflects the pulse of the construction industry but helps define it.

For those shaping the future of the built environment, Architectural Building Week in Sofia offers inspiration, innovation and international connections – all in one place, hands-on and forward-looking.

The Architectural Building Week takes place for the 26th time on 4 days from Wed., 11.03.2026 to Sat., 14.03.2026 in Sofia.
