Hi, thanks for asking! There may be some slight differences in style; what I'd suggest is 1. create a new node near the N end of the current building, with all the current building's tags copied over, then modify the tags. (Keep the address info, but remove "building", and change amenity to construction:amenity, since the church will return at this location). 2. delete the current building. 3. Draw an area covering the construction zone, and tag it "landuse=construction".
