The cost of strengthening and\u00a0refurbishing heritage buildings is a challenge that many building owners will relate to so, when I asked about the costs for the Old Choral Hall project, the height of the raised eyebrows said it all, though the final figure has yet to be disclosed. As such, Waipapa Taumata Rau University of Auckland<\/a>\u2019s commitment to this demanding project is commendable and, in turn, the outcome is a\u00a0triumph.<\/p>\n

The refurbished complex contains 4000m2 of floor space. There are two 100-seat lecture theatres, various meeting spaces, as well as offices for students and staff. Circulation throughout has been substantially rationalised, addressing what many in the project team described as a \u201crabbit warren\u201d of spaces \u2014 the result of nearly 150 years of changing uses and\u00a0adaptation.<\/p>\n

Four key periods of construction, including the new additions, make up the\u00a0complex.<\/p>\n

The original building, at the heart of the complex \u2014 the Choral Hall \u2014 was designed in a classical revival\u00a0style by Edward Mahoney for the Auckland Choral Society and opened in 1872. It was substantial, with seating for 1100 people. The University had strong associations with the building even before they bought it, just prior to WWI. For example, the graduation of Kate Edger \u2014 the first woman to gain a Bachelor of Arts degree in the British Empire \u2014 was held at the Hall in 1877 and, from 1888 onwards, it was used for\u00a0teaching.<\/p>\n

Subsequently, a further wing was added on each side of Choral Hall, to house the science department. One wing was added in 1919, along the south-western elevation of Choral Hall, facing Alfred Street, and another was added, towards the north-east, in 1925. The 1925 wing was designed by American architect Roy Lippincott, who also designed the University\u2019s iconic Clock\u00a0Tower.<\/p>\n

Over time, various unsympathetic additions and alterations took place, resulting in a less cohesive building. Project architect\u00a0Architectus<\/a> explained that many of the changes were additions rather than\u00a0deletions so, by removing these, most of the significant heritage fabric could be uncovered and was still intact. Unveiling and responding was a core part of the project process, with many surprises along the\u00a0way.<\/p>\n

One of the significant discoveries included an old well, which is believed to predate Choral Hall itself. It now sits proudly displayed below a glass floor. A less pleasant discovery was the fact that the Lippincott wing didn\u2019t have any foundations! I was told that \u201cthe client was very patient\u201d, despite the unpredictable nature of this discovery process. The process was made even more challenging by the Covid-19 pandemic disrupting the project, which had started in\u00a02019.<\/p>\n

A gratifying honesty flows through the interior spaces, honouring the principles set out in Section 5 of the\u00a0ICOMOS New Zealand Charter 2010<\/a> \u2014 New Zealand\u2019s key guiding conservation document \u2014 which advises that conservation should recognise \u201cthe evidence of time and the contributions of all\u00a0periods\u201d.<\/p>\n

The accretions of time are evident, with each period\u2019s time stamp identifiable, and even the evidence of the unsympathetic, removed elements has been captured \u2014 they are all part of the building\u2019s history, after all. Many building features are presented raw, as found, with no attempt to smarten them up and return them to a former, pristine\u00a0state.<\/p>\n

<\/p>\n

New and existing materials sit comfortably alongside one another.\u00a0Image:\u00a0<\/p>\n

This principle of raw honesty also extends to new elements, such as the shotcrete shear walls, which were originally going to be over-clad but, upon seeing them in place, the team decided to leave them exposed \u2014 this way their rich materiality, function and story is evident at a\u00a0glance.<\/p>\n

Only a few concrete shear walls had to be inserted, and some steel columns and beams also remain from earlier strengthening projects, but most of the seismic strengthening action is undertaken by timber strongbacks. These essentially form a new \u2018skeleton\u2019 on the interior of the building, supporting it from within. It is more sustainable to use timber strong-backs than\u00a0it is to use concrete or steel; the strong-backs also have the benefit of being virtually fully reversible. Reversibility is an important conservation principle \u2014 not because earthquakes might cease to occur in the future but because an improved solution (or a new use) may be developed at a later stage, thus allowing the building to be returned to its previous state and the new solution to be\u00a0implemented.<\/p>\n

The exception to the internal strengthening is the reconstructed portico, which has been added externally along the Symonds Street frontage. Concealed within the hollow, lightweight concrete colonnade and pediment are steel columns and beams, which support the front fa\u00e7ade. The original portico was removed as a precaution following the Napier earthquake in 1931 and, for nearly 100 years, the building sat strangely maimed, as though it were missing a vital body\u00a0part.<\/p>\n

Returning the dignity and cohesion of this frontage was an important objective of the reconstruction\u00a0project, explains Robin Byron, who was the\u00a0Heritage New Zealand Pouhere Taonga<\/a> representative working alongside the project team for its duration. She advocated for the reconstruction of the portico from the outset; however, as a costly undertaking for the aesthetic benefit alone, it wasn\u2019t until Beca, the structural engineer, identified the need to strengthen the front fa\u00e7ade that the two objectives were aligned and the reconstruction became a\u00a0reality.<\/p>\n

Under the guidance of conservation architect\u00a0Archifact,<\/a> the portico was reconstructed, based on old photographs of Choral Hall, remaining evidence at the site, as well as the detailing of the columns and pediment at the Auckland Baptist Tabernacle, which were believed to be similar. Unfortunately, no drawings of the portico\u00a0survive.<\/p>\n

Reconstruction is perhaps the most challenging of all conservation processes and a term heritage professionals often approach with scepticism. It is defined in the ICOMOS Charter as building \u201cagain as\u00a0closely as possible to a documented earlier form, using new materials\u201d. It should not be, but often is, confused with restoration, which involves reassembly and reinstatement using existing materials, such as fallen masonry or removed joinery that has been in storage, for\u00a0example.<\/p>\n

Reconstruction goes hand in hand with loss \u2014 it generally follows wars or natural disasters. In New Zealand, our heritage is no stranger to loss, thanks to our high seismicity. Elements such as parapets, pediments and finials have often been removed as a precaution or damaged as a result of earthquakes. Like the portico at Old Choral Hall, their loss often dramatically alters the proportions and reading of the building and, hence, reconstruction of these elements can, with strong evidence, be\u00a0supported.<\/p>\n

However, reconstruction also presents an interesting conundrum. While a vital part is reattached, returning\u00a0the proportion and coherence of the original, the materials are new \u2014 in the case of the Old Choral Hall portico, even part of the function is new. I reflected on the project with Byron for the purposes of this article and we wondered if, in hindsight, and without disrupting the coherence of the reconstruction, more of a tangible clue could have been provided about the portico\u2019s dual function. Seismic strengthening is our heritage \u2014 it is a vital part of our New Zealand story and, amidst all of the honesty that flows through the rest of the project, both externally and internally, evidence of this part of the story would have been a welcome final\u00a0touch.<\/p>\n

Overall, it is great to see this Category 1 Historic Place so successfully revitalised and the next chapter of its story begin to unfold. I can\u2019t help wondering how it will be used, and by whom, in another 154 years \u2014 in the year\u00a02180.<\/p>\n
