Unable to answer "Does this street have a sidewalk?" for https://osm.org/way/20179160 via StreetComplete 33.1:

There is a footpath along both sides of Halls Close, but it is not a "pavement", When the estate was built (1990?) the less used footpaths in Halls Close, Barn Close, Scholar Place and other local streets were left as grass. AFAIK, this was just a cost cutting measure.
This is complicated by the fact that the highway boundary markers have since eroded and several house owners have planted shrubs in the grass footpaths and made them impassable.
Street Complete needs a "grass footpath" option or a way to change the footpath surface.
