Christ Church - Walshaw
Stabilisation of the two east gable pinnacles together with repointing to the east gable, reglazing to the west window including adjacent masonry repairs and renovated rainwater goods to the whole building.
Christ Church Walshaw is a prominent Victorian Gothic Church designed by the local Bury Architect Lawrence Booth in 1888. The building is listed grade 2* and is situated on a prominent plateau with open views to the North and East towards Bury making the building a very significant local landmark.
High level inspections revealed significant cracks to the supporting columns to the ornate pinnacles flanking the east end gable. These items were restrained with wrought iron dowel fixings but the metal had corroded resulting in delamination of the stone supports. There was a very great risk of collapse to either of the 4 tonne capstones to each pinnacle.
The church was also suffering from considerable water ingress through the west window. A report on the stained glass revealed substantial damage to the lead with a recommendation for reglazing to the whole window.
Byrom Clark Roberts assisted the Church PCC in obtaining a Repairs Grant from English Heritage towards the urgent repairs. This was supported by the Heritage Lottery Fund.
Challenges + Opportunities
The project consisted of the stabilisation of the 2.no east gable pinnacles together with repointing to the east gable, reglazing to the west window including adjacent masonry repairs and renovated rainwater goods to the whole building.
The challenge was to safely dismantle the existing two pinnacles; each estimated to weigh in excess of four tonnes. New stone support columns were fabricated consisting of hollow cored stone shafts surrounding new ss Macalloy 25mm diameter hi-tensile rods which were dowelled and resin anchored into the base and capstones. The result is an exact replica of the original detail but with new stone shafts.
The existing support shafts consisted of solid stone with small wrought iron dowels to top & bottom which had badly corroded. The decision was taken to use grade 316 Macalloy stainless steel rods and to have these effectively supporting the top cap with the stone shaft as a cosmetic surround.
The philosophy in this case did not seek to change the appearance externally but merely to alter the defective original structure for a more durable and effective solution.
Byrom Clark Roberts provided Architectural Design and Specialist Conservation Consultancy Services regarding the Repairs Grant Process. Byrom Clark Roberts Structural Engineers designed the Macalloy support structure to the rebuilt pinnacles.
“In every respect - planning, preparation, implementation – our Restoration Project was blessed by the wholehearted commitment of Byrom Clark Roberts.”
