We did it! The construction certificate has just been issued for major restoration and conservation works to the St Andrews Congregational Church in Balmain (where the Balmain markets used to be held). Built in 1854 it’s one of Sydney’s oldest.
It's our largest and most complex conservation and remediation work to date. Initially engaged as the principal (heritage) architect and heritage consultant, we continue to act as client representative and superintendent of works.
It's also a fantastic collaboration with TTW (as structural engineers) and Traditional Restoration Company (as stone conservators). Complex planning, code compliance and structural issues (and Council matters) meant planning and approvals took a full seven months!
The Story:
In late 2020, Studio Trudeau was engaged to determine and resolve rising damp and areas of stone decay to the base of the tower. Noting other issues, we commissioned a full external assessment to find that (among a range of other issues) the church spire itself was at risk of collapse!
The eight supporting columns of the spire have full depth vertical cracks, and many areas of stone are beyond repair.
After exploring all avenues, it was decided that the spire must be carefully dismantled, with the columns recarved from new stone to match the existing and an internal seismic frame of stainless steel inserted, before being rebuilt, re-using existing stone wherever possible.
Along with replacing a concrete slab floor with raised timber, a range of other repair works will also take place, including poulticing and salt remediation, repointing with lime mortar, and replacement of damaged external stone.
Can't wait to get started - next week! Watch this space for more discussion, photos and details as works begin.
