Hall layout: Updates in some sections at BAU 2021

February 15, 2020
  • 200,000 square meters of space in 19 exhibition halls
  • New in 2021—modular construction and architectural building materials
  • Strong demand for climate change solutions

The new halls C5 and C6 prompted a major re-shuffle of the sections at BAU in 2019, so adaptations for BAU 2021 are only moderate in scale. The basic layout of the sections in the halls remains largely unchanged, but there will be an update in some exhibition sections. In 2021 BAU will again be taking up 200,000 square meters of space in 19 halls. Excluding the open-air site (which is not used at BAU because of the weather in January), this represents full capacity utilization of the Messe München exhibition center. Set out below are details of what to find where in the individual halls at BAU 2021:


  • Traditionally the sections on stones / soils / joining solutions are located in Halls A1 and A2. New here in 2021 are modular construction and architectural building materials. The theme of carbon concrete has been added to the product range. So, this area now includes the following: Concrete/porous concrete/reinforced and carbon concrete, pumice/fiber-cement building materials, sand-lime brick, facade systems, plasters, screed, insulating materials and the themes of dry interior finishing and prefabricated/modular construction.
  • Roof tiles and roof construction will again be taking up all of Hall A3. The brick and tile industry will be showcasing its entire repertoire—from masonry blocks and roof tiles to roof windows, roofing membranes and entire facade sections.
  • In Hall A4 the section on tiles / ceramics will feature more exhibitors and more space, and will also include the theme of stone / cast stone. By increased integration of the theme of marble, this section of the exhibition is therefore even more attractive. “This hall serves as an interlinking element between facade elements and floor coverings,” explains BAU´s Exhibition Director Mirko Arend.
  • The manufacturers of floor coverings took up two entire Halls, A5 and A6, for the first time in 2019. Because of strong demand in this area, that situation will continue in 2021. The exhibitors are showcasing their entire repertoire of elastic (linoleum, PVC, rubber, cork) and textile floor coverings to laminates and parquet, including laying techniques and applications.


  • Together Hall B1 and Hall C1 form a single exhibition section. Here the focus is on facades, systems and profiles of aluminum. The 20,000 square meters of exhibition space here also includes machinery for aluminum and steel processing.
  • More space is being given to the section on energy, building systems and solar technology in Hall B2—a result of the strong demand for products and solutions to respond to climate change. Manufacturers will be showing how technological solutions—air-handling and solar construction—can be integrated into buildings in both an energy-efficient and architecturally attractive way.
  • Also in Hall B2: Building and facade systems, plus steel profiles, as well as systems, products and surfaces of stainless steel, zinc and copper.
  • Gate and gate-drive technology will again be in Hall B3. An important part of this hall is an impressive display of intelligent parking systems.
  • The themes of locks, fittings and security form a single section in the exhibition. Doors and windows of wood, aluminum, plastics and glass are at the heart of Halls B4 and C4. The offering is rounded off with a wide range of locks and fittings, plus anti-intrusion systems, door-drive technology and access systems.
  • Hall B5 is once again the place to see an extensive range of products and solutions from the wood industry. Covered here are the themes of timber construction, prefabricated construction, interiors, wood derivatives, staircases and veneers.
  • As at BAU 2019, chemical building products will have an entire hall, Hall B6, dedicated to this theme. Here leading manufacturers will be showing how and where their extensive ranges are used: plasters, varnishes, paints, adhesives, insulation (thermal, noise, fire) and seals.


  • The themes of light in combination with smart building were introduced in 2019—and straight away they were a resounding success. In 2021, too, Hall C2 will again combine the theme of light with the theme of smart building / building automation. In the area on light, the focus is on daylight deflection, lighting concepts, daylight vs. artificial light. Exhibitors of solutions in building automation and management are also gathered together here, and form a link to the existing areas such as facade systems, windows and doors, and energy technology.
  • The exhibitors from the glass industry moved in 2019 from Hall C2 to Hall C3. And that is where they can be found again in 2021. Leading companies in the international glass and glass-facade industry will be exhibiting the latest developments and products in the areas of glass and glass architecture.
  • The section on construction tools, which is very popular with the visitors, will again have a dedicated area to itself, in Hall C6. The “Tradesmen Meet” platform, where special practice-oriented demonstrations and lectures of interest to building tradesmen and -women take place, fits perfectly into this setting.
  • BAU-IT, which together with the new digitalBAU (which premiered in Cologne from February 11 to 13, 2020), is the biggest display of its kind in Europe, keeps its place and so, as in 2019, will be taking up an entire hall—Hall C5. Here visitors can find IT solutions of all kinds for tendering, contracts, billing, project planning, measurement technology, project management and controlling. The “Digital Village” is also located in C5. Here, start-ups, software suppliers and companies from the building industry will be presenting concepts and ideas for digital planning and building in the future.

Hall B0

  • “Investing in the Future” is the motto of the smaller Hall B0. Gathered together here are representatives from universities and institutes and associations from the building industry. In the forum in Hall B0 the themes of building research and grants are top of the agenda. For this a dedicated lecture program has been put together on the subject of renovation and modernization of existing buildings. The offering in this hall is aimed primarily at young professionals between the ages of 25 and 35 who have already gained initial experience in the sector and want to take the next step.

The site plan for BAU can be found on the website:

The broad-ranging spectrum covered at BAU 2021 is tailored to all the key visitor target groups of interest for the building sector.

  • Planners: Architects, interior designers, engineers, structural engineers, local and central-government building authorities, energy consultants.
  • Investors: Housing associations, private and local-authority developers, real-estate managers, fund managers, retailers/retail chains, facility managers.
