first implemented: valuable objects were relocated or
shielded, fire-resistant sheeting was laid, and a birdcage
scaffold with Acrow props provided internal structural
support. A drop scaffold was then installed to facilitate
ceiling access from above.
Timbers supporting the ceiling had accumulated grime
and were dry-brushed, vacuumed, and treated with white
spirit. Damaged joists were reconnected using stainless
steel angle cleats and coach screws. Other weakened
joints were stabilized with screws, metal brackets, and
stainless steel strapping. These reinforcements are essential for supporting the ceiling while minimizing future
stress on the structure.
Entablature and Ceiling Restoration
The deteriorating timber and plaster entablature was
similarly cleaned, aligned, and reinforced. Custom-fabricated steel straps—38 in total—were strategically placed
to restore its structural cohesion. Moreover, the copper
wire hangers once suspending the plaster ceiling were
replaced with stainless steel wire ropes, attached to a
modern auxiliary steel framework made from Unistrut
channels. This new substructure provides better support
and adjustability.
To stabilize areas showing severe cracking or distortion,
additional stitching was carried out using wire ropes and
washers. Where plaster decay was extreme, laths were reinforced with epoxy resin bridges. Overall, this work
maintained the integrity of the original materials while
ensuring the safety and longevity of the ceiling.

Plasterwork and Decorative Repairs
Cracks in the ceiling and wall plaster up to 3mm wide
were filled using a fine filler; larger ones received lime
mortar. Damaged sections from water ingress were either
carefully restored using original laths or reconstructed
with suitable replacements. Missing decorative details
were handmodelled using lime plaster to retain artistic
fidelity.
Decorative features—walls, pilasters, medallions, and
fireplaces—received similar attention, blending conservation techniques with traditional materials to uphold the
Hall's unique character.

Art Historical and Paint Conservation
The Great Hall’s stucco surfaces underwent detailed paint
analysis. Sixty samples were collected for microscopic pigment and layer composition analysis. This revealed historically significant schemes like the ‘Etruscan’ red and a
blue-green rag-rolled finish, which are being recreated as
part of the conservation process.
Modern, incompatible paint layers that obscured fine
plaster details or failed due to damp conditions were
removed using steam cleaning or chemical strippers. Each
area was visually and chemically assessed to ensure no
damage was done during this delicate process. After
