Most of the images of the Guildhall show the rear of the hall that is viewed from the market place in the High Street such as this one here SU3645 : Andover - Guildhall this is the actual main entrance on the other side.
SU3645 : Andover - Heath Vale This large semi-detached house, originally the site of 47 and 49 Winchester Street, which stood over a passageway to the cul-de-sac Heath Vale, has been demolished since this photo was taken. It has been replaced by a very 'modern' 3 storey pair which also straddles the passageway (streetview https://goo.gl/maps/u3QKW21HYhmDHhzW9 ), presumably flats.
