Grade II, in a Conservation Area
11 & 12 St. Mary’s Square are unusual vernacular cottages, and along with part of 10 St. Mary’s Square, once formed a three-bay house. Behind the brick facade added in the early 19th century, there is an oak timber frame dating back to at least the 17th century. In the early 18th century, the house was subdivided to form three cottages. The roof covering is corrugated iron, painted with bitumen, and covers remnants of the original long straw-thatched roof. The cottages were listed with the corrugated iron roof, known locally as a Lincolnshire ‘tin hat’, which was installed, like others in Lincolnshire, during World War I as a protective measure. The current owner purchased the cottages in 2014, knowing the cottages had suffered from ill-considered repairs, including the installation of an injected DPC and inappropriate modern plaster finish trapping moisture around ancient oak beams. The 18th century tumbled gable end was partly covered in hard cement render, which was shaling away and becoming dangerous. A sample was removed and showed extensive brick repairs were needed.
Production of a specification for works of repair, which was agreed with the local authority conservation officer. Works were overseen by Liz Mayle who also sourced appropriate materials and craftsmen for the removal of hard cement render and replacement of around 700 badly damaged bricks, which were replaced with hand-made wood-fired bricks from H.G. Matthews. Quality brickwork repairs were undertaken by local specialist brick craftsman, Jason Scott (Liz Mayle has contact details). The building was fully repaired inside and out, with repairs to the ‘tin hat’ roof, replastering with lime plaster and joinery repairs to give these delightful cottages a new lease of life without spoiling architectural integrity.
