Bielefelder Bautage Bielefeld

The Bielefelder Bautage is the leading information and advisory trade fair for construction, housing, modernisation and energy in the Ostwestfalen-Lippe region. Held annually at Stadthalle Bielefeld, the event brings together up-to-date expertise, innovative products and practical services for anyone planning, upgrading or improving the energy performance of their home.

The event is organised by S.U.W.A. Messen und Veranstaltungen, an experienced exhibition organiser specialising in consumer-focused formats. In addition to the Bielefelder Bautage, the company delivers further building and home improvement fairs at various locations, connecting regional tradespeople, national suppliers and professional service providers with an audience ready to invest. This approach gives the event its distinctive profile: rather than a simple product showcase, it serves as a platform for face-to-face discussions, tailored advice and well-informed decision-making.

The Bielefelder Bautage covers the full spectrum of contemporary building and residential projects. Visitors can access expert information on new builds, conversions and project planning, as well as refurbishment, renovation and modernisation of existing properties. A particular emphasis is placed on energy efficiency, energy saving and renewable energy solutions – from sustainable heating systems and photovoltaic installations to integrated energy concepts for residential buildings. The programme is complemented by topics such as sustainable, low-carbon construction, property and finance, interior design and home styling, as well as garden and landscaping. Security systems, smart home technologies and the latest product innovations also feature prominently. As a result, the fair offers both inspiration and practical pathways to delivery – from initial concept through to completion.

Exhibitors primarily represent the building trades, architecture, energy and building services engineering, real estate, financial services, interior fit-out, landscaping, and security and building technology sectors. Participants include regional specialist contractors, SMEs, energy consultants, banks and finance providers. The event’s strong regional focus ensures clear relevance to Bielefeld and the wider Ostwestfalen-Lippe economic area, with many solutions tailored to local building conditions, climate factors and funding schemes available in North Rhine-Westphalia.

The core audience comprises private homeowners, renovators, property owners and prospective buyers who are planning specific projects or seeking early-stage guidance. The fair also attracts industry professionals from the trades, planning and real estate sectors for networking and market intelligence. The combination of consumers and trade visitors creates a dynamic, practice-oriented environment. Expert talks, on-stand consultations, feature areas and technology showcases provide valuable guidance in an increasingly complex market.

Stadthalle Bielefeld offers an ideal venue: centrally located, modern and easily accessible by public transport and car alike. Its proximity to the city centre, the main railway station and parking facilities makes attendance straightforward. As a result, the Bielefelder Bautage has become a fixture in the regional events calendar and is widely regarded as a key driver for building and residential projects in Bielefeld and the surrounding region.

The Bielefelder Bautage will take place on 2 days from Saturday, 11. April to Sunday, 12. April 2026 in Bielefeld.
