Prefabricated housing market in Central and Northern Europe - Overview of market trends and development - Study extract
Management summary (1/2)

       The market study at hand analyzes the prefabricated 1+2 family housing market in Central and Northern Europe, covering the countries
       Germany, Scandinavia, the UK, Austria, Switzerland and Poland, and is based on primary and secondary sources of information

       The market volume of 1+2 family housing in focus regions is expected to display solid growth of 2.0% p.a. from 2017 to 2022, driven by
       a strong anticipated GDP development, favorable financing conditions, and governmental regulations and subsidiaries

       Among 1+2 family housing, the prefabricated housing segment (c.15% of all 1+2 family houses) is expected to further gain in relevance by
       growing at 3.2% p.a. from 2017 to 2022, driven particularly by an increasing demand for planning security and technology acceptance
       > Germany (c.25 k), followed by Scandinavia (c.13 k) and the UK (c.12 k) are expected to display the largest prefab volumes in 2017
       > Absolute volume growth is projected to be driven by Germany (3.1% p.a. in 2017-'22), the UK (3.8% p.a.) and Scandinavia (3.5% p.a.)
         – In Poland prefabricated housing is currently less popular, considerable catch-up effects are expected going forward (6.9% p.a.)

       Within prefabricated 1+2 family housing, there is a trend towards turnkey solutions with convenience and security as key drivers
       > Turnkey solutions are the prevailing prefabricated finishing type, accounting for c.50% of the market volume, and are projected to
         outgrow the prefabricated housing market in all focus regions (3.8% p.a. vs. 3.2% p.a. volume growth)
       > Germany (c.10 k), Scandinavia (c.8 k) and the UK (c.7 k) are the largest prefabricated turnkey housing markets in 2017 and are
         expected to grow at c.4% p.a. between 2017 and 2022

       The market value of prefabricated 1+2 family housing is expected to grow at c.6% p.a. between 2017 and 2022 in Central and Northern
       Europe due to favorable pricing trends (e.g. shift towards more expensive turnkey solutions and increasing wage levels)
       > Turnkey solutions are forecast to outgrow the prefabricated housing market with c.7% growth p.a.
       > Geographically, Switzerland (c.360 k per average prefabricated house), Scandinavia (c.330 k) and the UK (c.250 k) show the highest
         average prefabricated 1+2 family housing prices in 2017, while Poland (c.80 k) is estimated to have the lowest price level

Management summary (2/2)

       The route-to-market differs by focus region: In the DACH region (Germany, Austria, Switzerland), prefabricated 1+2 family houses are
       typically sold directly to end customers, while the UK has a higher share of intermediaries (i.e. developers and housing associations)

        The key buying criteria of customers are price/quality ratio, quality of sales, product customization and brand perception – Customers are
        increasingly willing to pay for superior quality, given the overall high investment combined with an expected long period of usage

        In the DACH region, several manufacturers of prefabricated 1+2 family housing exist, with vast differences in product price segment and
        level of finishing type
        > The largest manufacturers are DFH, followed by Equistone assets (Bien-Zenker and Hanse Haus), WeberHaus, FingerHaus and
          Polish-headquartered Danwood based on 2016 revenues
        > The majority of manufacturers have been able to gradually increase their revenues between 2012 and 2016, driven by a favorable
          market environment, which is expected to be the base for further growth going forward

       Specifically for Germany, the prefabricated 1+2 family housing market appears to be largely fragmented with the top 5 suppliers
       accounting for c.30% and suppliers beyond the top 5 holding market shares of below 3%
       > Within the prefabricated 1+2 family housing market, the turnkey subsegment reveals a similarly high level of market concentration
       > This market characteristic creates possibilities for M&A activity, which has intensified in recent years

        The entry of new manufacturers in the prefabricated 1+2 family housing market is hampered by several barriers – The main market entry
        barriers are related to technical capabilities, sales network with an attractive online channel, brand/track record and capital intensity
