Hallo,
why did you delete the two buildings?
I reverted this with www.osm.org/changeset/169174940
For their construction see https://www.cartoriviera.ch/gmf/photos_historiques/luftbilder/?type=ortho&east=2562460&north=1139594&url=https://data.geo.admin.ch/ch.swisstopo.lubis-luftbilder_schwarzweiss/lubis-luftbilder_schwarzweiss_000-218-812/lubis-luftbilder_schwarzweiss_000-218-812_op_2056.tif
