Hello Gregory

Thanks for your feedback. Yes, there were some houses I was unsure about.
I have sometimes used Bing for comparison, but it is difficult because of the offsets.
I have not thought about adjusting the offset in Bing. I will try that next time. I have tried changing the offset in both ID and JOSM in another task.
In project 12803, the instructions state that you must adjust the offset before starting. Is it ok to write the offset in the comments? The offset will probably be different from task to task. Here several houses are selected together and it makes sense to change the footprint - I could not get shift+ctrl+G to work in JOSM. What am I doing wrong?
