Role: Project Architect

Crosby Granger Architects are the inspecting Architects to St. Helen’s Church, a Grade I listed church that was recently admitted onto Historic England’s Heritage at Risk Register due to the condition of the masonry. The magnesian limestone had been pointed in a cement based mortar that was causing the heavy and rapid deterioration of the solid core masonry. To the chancel particularly, this, coupled with ingress at the wallhead had caused the medieval earth-core masonry to wash out, and to saturate the stonework from the inside out.

Phase 1 was completed in 2017, and saw the chancel re-roofed to resolve the issues of water ingress at the wallhead. This then allowed a period of drying of the stonework before the second phase of works was commenced.

 

With thanks to a major funding grant from the National Lottery Heritage Fund, Phase 2 was completed in 2019 that included a substantial stone conservation exercise to the entire building envelope, including stone repairs, indents, mortar repairs, friable stone stabilisation, complete re-pointing and localised thrown rough-casting to areas of vulnerable rubble, followed by traditional limewashing to all of the medieval rubble masonry to add an additional layer of protection in the traditional style.

Through careful opening up works during the project development phase, and investigations and consultation with a Materials Analyst we developed a repair mortar that was both compatible with the existing mortar, some of which was earth-based, as well as being an appropriate match for the very soft magnesian limestone.

As part of the main stone conservation project we assisted in facilitating the activities schedule, which included craft skills training, interpretation information, investigative archaeological digs, and a new guidebook.

DISCIPLINES COVERED IN COMMISSION:

 

• Site evaluation and historic building assessments including structural surveys,
• Production and review of Heritage significance statements,
• Technical advice on details of conservation and design for listed buildings,
• Application and gaining of statutory consents,
• Consultation with Historic England regarding the church’s admission onto the Heritage at Risk Register and agreement of repair methods,
• Consultation with a range of professional disciplines.

#CONSERVATION

A recent image of a scheme being developed at CGA within the Lake District National Park. With a close eye on traditional forms, mass, scale and materials, we aim to create a modest building and parking facility in a wooded setting which enables a wide range of problems on the highway to be solved.  More details to follow in good time.

Tolson's Mill is a former textile factory which dates to the 1880s. Aligned on a North South axis, the Mill comprises a five storey iron-framed structure and a smaller two storey annex to its northern end. CGA have been designing the new fit out and the modern extension to the Mill while also preparing an extensive repair schedule. CGA are working as part of a comprehensive design team which requires the coordination of a wide team of consultants including, Fire, Acoustics, M&E, Structures, Planning and CDM.

Set in an urban context in a poor and deprived area of Gateshead, St Chad’s was built as a ‘Cathedral for the Workers’ and is now on the Historic England Heritage at Risk register. The looming exterior does not prepare one for the shimmering interior, rich with a mix of high-gothic and rich fixtures and fitting from the Arts and Crafts Movement.
