The synod hall is prominently sited in an elevated position, making it an important focal point on the cityscape. It forms a component part of an ecclesiastical complex with Christ Church Cathedral, and the associated choir school. It was constructed to designs by George Edmund Street, as part of his restoration of the cathedral in 1875. Street's original design for the Synod Hall placed it to the south of the cathedral, but it was decided instead to situate it on the site of the Church of Saint Michael and All Angels, which dated from c.1815. The new design connected the synod hall to the cathedral by an elevated passageway over Winetavern Street, and incorporates the tower of the earlier church. The latter is visibly of an earlier date, the marked difference in the masonry providing a pleasing sense of contrast, as well as indicating the long ecclesiastical history of the site. This attractive building is well detailed and proportioned, with a variety of window openings which enliven the façade. Its construction attests to high quality stone masonry and artisanship, particularly evident in the fine carved detailing throughout. The masonry is similar to that employed in the adjacent cathedral, creating a pleasing sense of uniformity of design.
