Update: Not much at the moment. The insulation of the three windows has been plastered, but the final topcoat is still missing. Two of the three new doors/frames have been installed. Additionally, a small balcony photovoltaic system with 640Wp as a temporary solution. This can also support the new duo multi-split air conditioning for the bedroom and children's room. However, I am still waiting for the meter change for the photovoltaic system and the BAFA funding for the Klimaanlage heat pump. More was not possible because child #2 has not allowed much in the last 7 months and I myself was severely limited for several months due to a slipped disc.
