We are continuing to invest in climate protection: in addition to improving our indoor climate, we will drastically reduce our heating and cooling requirements in the long term by replacing all windows, from the basement to the offices to the workshop. We would like to thank Holzbau Lafrenz (https://www.lafrenz-holzbau.de/) for their excellent and speedy work. As part of the window renovation, we chose a new color and repainted all other (rather aged) surfaces accordingly. We would like to thank the painting company TIEBE (https://www.maler-tiebe.de/) for this.
