The upper floor was approached from the paved area below by a spacious flight of stairs on the north-west side, contained the ancient Council Chamber, which was also used for the County and Borough Courts of Quarter Sessions, and for other public purposes.

1828 In consequence of the old edifice having become dilapidated and considered an obstruction to the carriage-way to other parts of the Borough, the authorities under powers of the Newbury and Speenhamland Improvement Act of 1825, had the historic building razed to the ground, the beautiful carved internal fittings and highly enriched external ornaments were sold to the rich for a mere bagatelle.
Among the projects proposed by the above Act (1825), were a new Town Hall, a new Gaol and House of Correction, widening of the Mansion House corner, and new street from Bartholomew Street to Cheap Street through the ‘Catherine Wheel’ yard, and various other improvements.
