Blackfriars' Hall

The hall, a picture gallery at the back of the Georgian house, is built in a Classical Revival style tempered with early twentieth-century decorative details, most notably two Art Deco chandeliers. The hall is 16 metres in length, 9.39 metres in breadth, and 5 metres in height. Laid upon the wooden floor is a chequered pattern rug – manufactured in Perth in 1932. The alternating black and white squares, ‘symbolise the duality of human life and the constant interplay between virtue and vice, wisdom and ignorance, light and darkness’.

The hall's outstanding feature is the mural decoration, conceived and executed by Thomas Hutchison Peddie (1884–c.1950s), a Perth-born artist and illustrator who achieved considerable distinction in London. Peddie’s self-portrait is above the organ at the north-east corner of the room.

The north wall bears a triptych depicting the building of the Abbey of Scone in 1115: Alexander I, King of Scots, is shown interviewing the Master Mason and being shown the plans of the abbey under construction, with an apprentice holding the plans and the soldiers of Military and Hospitable orders in the foreground. 

The east frieze depicts the handing down of the emblems of the masonic craft — the working tools and mode of dress — through the centuries from the eleventh century to 1932, with alternate panels showing the sands of time balanced by the flaming sword of truth. 
In the middle of this wall is a painting of King James VI on 15 April 1601, depicting the occasion of his initiation into Scoon & Perth Lodge No.3. 

Along the south wall, a mosaic rendering depicts the story of Hiram Abell, and beneath it King Solomon viewing the Temple. 
The south-west wall shows a supplicant on a bare crag, arms outstretched before ‘the all-seeing eye of God set in a double equilateral triangle, surrounded by cloud formations symbolising the four elements — Earth, Air, Fire, and Water’.

A frieze on the north wall and along the east wall runs Jacob's Ladder with traditional masonic figures of Faith, Hope, and Charity.
