Construction accounts for 4 percent of German gross domestic product (GDP) and, with 2.5 million people working in more than 300,000 companies, it is a major employer.
"More and more Germans are putting their money into property," said Hans-Werner Sinn, head of the Ifo economic institute. Ifo's construction sector index rose in November to its highest level since German reunification in 1990.
The index, which measures sentiment in the sector, dipped slightly this month but remains high as the European Central Bank's low interest rates turn more Germans away from regular saving funds and towards property investments.
This increased private sector demand is helping the property market further up the scale from the entry level homes built by companies such as Bauer Holzsysteme in Neukirch.
For instance, shares in real estate group Patrizia Immobilien, which is building 4,000 new flats in cities including Munich, Hamburg and Berlin, have jumped around 120 percent this year.
Still, the construction industry has a way to go to match the boom it enjoyed when much had to be rebuilt in the former communist east Germany following reunification. Turnover in core construction business has increased in the last few years but in 2014 remained about 15 percent below levels of the mid-1990s.
