Here is the promised update. The roof is being installed. I assume that it is completely finished in about 2 weeks. Also, the walls of the two lower apartments were completely finished and plastered. Electrical and water connections were also relocated. Very soon we will tackle the upper floor. Another update will follow in March.
Here is finally the long-awaited update of house 2. 3 months after the start of construction I can only say that a lot has happened again. The last ceiling tile for house 2 is ready. Now come the posts to the roof and then covered. Next update then in January for house 2.
Construction of the second house was on 27 August. Here are the approved blueprints.
