Steeped in history, the 16th century Tudor House Museum has witnessed many changes in Monarchs and tenants as well as a little movement itself.
As consultants to the museum PHICs were commissioned to oversee the complex 1st floor and loft conservation repair package. .
In these early photographs it is clear that two "flat roof" dormer windows were present on the Friar street elevation. These were additions to the original building, the flat roof design indicating they were most likely added in the late 18th or 19th century. They were removed during the mid 20th century and the roof and loft room were again closed-in.
When the dormers were added, the builders had cut through the oak purlins. Timber framed and lime plastered buildings cope with movement very well and the distortions in our black an white Tudor buildings are almost synonymous with the period. Their almost flexible structure is far more suited to such movement than modern day building. However when the dormers were later removed, no support was given to the cut purlins and the roof and building began an exaggerated shift. Over decades the movement split main beams, twisted floor joists away from the fixings and created uncertainty to one of the oldest surviving Tudor strap-work ceiling in Worcestershire.
Following initial investigations and HLF grant funding we were commissioned to oversee the tender process and principal design and project management elements in-house for the Museums trust.
The roof without dormers.
The original Tudor ceiling was secured before works commenced.
The ceiling had received multiple repairs and modern paints were clogging the detail and delaminating the surface.
The “shift" of the building was at first most apparent when looking up to the cornice in the Tudor bedroom
The “lost area” scarring where the dormers had been removed. Cables were fixed to a tray that spanned the cut purlin without support.
The building had moved and the floor joist floated short of reaching to main beam.
New oak was introduced between the cuts and the purlin was braced and supported with stainless steel plates and coach bolts
Stainless steel supports were added where the loft beams had become unstable
Stainless steel brackets were manufactured to ensure the floor joists rested on the main beam.
Replacement oak lathes were need and SS screw and wire fixings were applied to re-secure the ceiling from above without damage to the surface.
Once secure the C1540 ceiling surface was carefully cleaned to reveal the finer detail of the hand modelled ceiling.
