When Rebuilding or Returning to an Earlier Design Is Appropriate

A return to an earlier design is a restoration only when the earlier state is known from evidence, not assumed from preference. Under the Organ Historical Society’s guidelines, restoration means direct action intended to return the organ to a known or assumed past state, and the guidelines tie that work to respect for the historical evidence that remains in the instrument and to clear indications of the earlier state. The Institute of British Organ Building’s Historic Restoration accreditation category is defined the same way from the other direction: work that deliberately avoids altering the existing instrument tonally or mechanically, with the single exception of a carefully researched and documented return to a specific earlier state.

Both formulations make the evidence the gate. If the surviving material and the records cannot establish what the earlier state was, the work being proposed is something other than a return to it, whatever it is called.

Evidence of that kind comes from the instrument itself and from its records, and no treatment should be inferred for a particular organ without that physical and documentary evidence in hand. How instrument-specific evidence is weighed, and what makes an organ historically significant in the first place, are covered under Pipe Organ Restoration and Rebuilding.

The state an owner returns an organ to does not have to be the state in which it was first built. The Organ Historical Society’s definition speaks of a known or assumed past state, which permits an earlier state other than the original as the target, so an instrument altered more than once may be returned to a documented intermediate state rather than to the builder’s first scheme. The practical consequence is that the word restored, on its own, does not tell you an instrument is as it was first built. An owner reading another instrument’s history, or a proposal for their own, should ask which state was the target and what evidence fixed it. What originality means when an instrument has passed through several hands is a separate decision with its own page under Pipe Organ Restoration and Rebuilding.

Conservation bodies that have published on this question advise against rebuilding or altering an instrument they treat as significant or historic, each within its own stated scope. The Organ Historical Trust of Australia and NSW Heritage guide of 1998 states that a significant organ should not be altered through enlargement or rebuilding because its significance may be compromised; that advice is conditioned on the organ having been found significant, which the same guide makes the first step of any project.

The British Institute of Organ Studies, in guidance dated 2024 and addressed to historic instruments, states that subsequent alterations made to keep pace with changes in fashion weaken the builder’s original concept, and warns owners against altering organs to conform to tastes in playing that the maker did not envisage. The same body defines restoration as returning an organ to its original state, or to as near its original state as is possible, and expressly distinguishes that from rebuilding or alteration.

The Organ Historical Society’s 2008 guidelines state that interventions should not modify the known aesthetic and physical characteristics of an organ, especially by removing or obscuring historic material or through non-essential re-voicing, and that enlargements or modernizations should be strongly avoided whenever possible; the word is avoided, not prohibited, and the guidelines are advisory.

Church of England guidance frames the choice for its own parishes around historic value and basic soundness. The national ChurchCare guidance states that destroying or substantially altering an historic instrument is poor stewardship and a loss to cultural heritage, and that if the organ is of historical value or is fundamentally sound, the best advice is to restore it. A diocesan advisory committee note from 2016 contemplates replacement by a new or secondhand instrument where the existing organ is in a poor state. Neither source sets out criteria for identifying an instrument that is a poor candidate for restoration, so that judgment is left to the individual case.

Organ-building sources describe rebuilding as a distinct and legitimate category of work rather than as a failure of restoration. Buzard Pipe Organ Builders, describing its own services, lists rebuilding separately from restoration and describes it as making additions or modifications in keeping with the character of the organ’s existing tonal palette; that is one firm’s terminology. Andover Organ Company describes rebuilding as work that helps existing instruments achieve their full mechanical and musical potential, which may include judicious tonal changes or additions; that is a company self-description, and full potential is an evaluative judgment about what the instrument should have been.

The American Institute of Organbuilders’ Guidelines for Fine Organbuilding, a 1994 text reprinted in 2020, state that any old pipework incorporated into a new or rebuilt instrument, whether in original or altered form, should be repaired or reworked so that it will function as well and last as long as new pipes; that is a performance standard for retained pipework in a rebuilt instrument, not a position on whether the instrument should be rebuilt. John Bishop, writing an opinion column in 2009, frames the governing tension as retaining an organ’s musical and artistic qualities while keeping in mind that the future of the pipe organ depends on an appropriate balance between artistry and expense, which is an identified practitioner’s view rather than an association standard.

The positions above are addressed to different instruments and different readers, and that is where the owner’s decision starts. The conservation advice is conditioned on significance, so the first question is whether this organ has been found to be significant, which is a separate decision with its own criteria and its own page. The builders’ descriptions are of what those firms offer, so the second question is what a given proposal actually means by the word it uses, which is a matter of reading its scope rather than its title. Neither question is answered by taking one of the published positions as the profession’s settled view.

John Watson and Robert Barclay, in a 2014 reference-dictionary entry, define restorative conservation as an approach that selects the most effective and least intrusive treatment from several options and gives preserving material evidence as much weight as returning the instrument to a past state. Their five decision rules are to document and preserve damaged historical components when removal is necessary; to keep interventions minimal, documented and detectable so that the evidence is not falsified; to date new parts or make them recognizable on close examination; to choose removability over irreversible treatments; and to recognize that some instruments serve history better by remaining unplayable. The rules are the authors’ formulation rather than an association standard, Watson co-chaired the Organ Historical Society guidelines revision so the two are related but not identical, and the fifth rule is the one performing musicians most often contest.

Other published positions hold that restoration and the preservation of evidence work against each other. Darryl Martin, conservator at the National Music Museum, is quoted in a feature published by Early Music America as holding that restoration can be the exact opposite of conservation in some ways, because the restorer is actively doing things to the instrument that are irreversible; that is an individual’s quoted view, not a museum policy. The publisher’s description of Watson’s own book Artifacts in Use states his central contention that preservation-worthy historical evidence tends to be lost during conventional restoration, and presents that loss as the paradox affecting heritage pipe organs.

E.C.C.O., the European confederation of conservator-restorers, distinguishes its profession from allied fields on the ground that its primary aim is the preservation of cultural heritage as opposed to maintaining or repairing objects in a functional sense, which places an organ builder restoring a working instrument in both fields at once. From the other side, John Bishop argues in the same 2009 column that a literal restoration cannot include new trackers even if the old ones are hopelessly broken, so that literally restoring an organ can produce an instrument that cannot be played. These are competing positions, and they are not merged here.

When an owner decides that playability governs and historic material will be removed, the guidelines make the record the minimum obligation. The Organ Historical Society’s guidelines contemplate that removal of historic material may be unavoidable, and in that case require the affected components to be documented in their pre-restoration state first. That is a documentation requirement, not permission; the judgment about whether removal is warranted rests with the project. Which records the owner should receive, and how reversibility and original material are handled in the work itself, are separate decisions, each with its own page under Pipe Organ Restoration and Rebuilding.

A return to an earlier state has been carried out on a documented instrument. Hook & Hastings Opus 1573 of 1893, built for St. Dominic’s Catholic Church in Portland, Maine, was dismantled and stored by the Andover Organ Company and David Wallace after the church closed in 2001, restored to its 1893 specification with its 1964 modifications reversed, and inaugurated at Christ Church, Rochester, New York, on 30 November 2012. Its original Hook & Hastings chests were kept intact and unaltered, and a new chest was added for a 16′ Trombone taken from William A. Johnson Opus 66 of 1857, so the instrument now carries documented non-Hook pipework on a new chest alongside the reversal. The account is an institutional instrument page rather than a technical report, and it establishes that the reversal was done there, not that it is generally achievable.

A rebuild, by contrast, has meant keeping the sounding material and changing what drives it. Andover Organ Company records that at St. John’s Seminary in Brighton, Massachusetts, it took Hook & Hastings Opus 1833 of 1902, originally a two-manual tracker of 18 ranks, and reused the pipes, windchests and most of the original material as the basis of an expanded instrument with a new electric action and a new solid white oak console with a record and playback module, giving a final specification of 40 stops, 34 ranks and 1,994 pipes.

The firm’s own view is that the result still sounds very much like a Hook & Hastings organ, but one from an earlier and better period; that is the builder’s aesthetic judgment, not a measured finding. The source presents the project as a rebuild and not as a restoration, which is the distinction that matters here.

A restoration after a destructive earlier rebuild shows the limits of a return to an earlier state. Johnson & Son Opus 577 of 1882 was converted to electric action in the 1930s by William Bardroff & Son, in the course of which the original console, stop and key action were destroyed and a new electric console was placed at a distance from the organ; the once-stenciled case pipes were painted over, and the instrument eventually became unplayable.

The restoration begun in 1991 studied period Johnson instruments, fashioned new case panels to replace ones destroyed by wiring and lighting, had the case pipes restored to their original stenciling and colors by Marylou Davis, Inc., and retained the original voicing. Two changes were made for present-day use, an extension of the pedal compass to 30 notes and a change of pitch to A=440, and the restoring firm states them as departures from strict restoration. The destroyed console and action could be replaced only with new work informed by other Johnson instruments, and the firm records the present-day changes as such rather than presenting the result as the 1882 organ unchanged.

Restoration is not the only treatment available, and it is not the default. In the Organ Historical Society’s taxonomy, conservation is the umbrella term, treatment is one of its four activities, and restoration is one of four kinds of treatment alongside stabilization, maintenance and reconstruction. The guidelines define stabilization as intervention intended to slow deterioration, and distinguish it from restoration, which aims to return the organ to a past state. An owner who is not ready to choose a target state, or whose instrument’s evidence would be put at risk by a return, can therefore choose to preserve what exists and slow its decline without committing to either restoration or rebuilding. Because a commercial proposal may use terms such as repair, rebuilding or restoration instead, an owner interested in stabilization may have to ask for it by name.

Where portions of the organ have vanished, the treatment that supplies them is reconstruction, not restoration. The Organ Historical Society’s guidelines define reconstruction as work depicting vanished portions of an organ and treat it as appropriate where documentary and physical evidence survive and conjecture is minimal. The evidence test is the same one that governs a return to an earlier state, but the work is different in kind because it introduces material the instrument no longer has. The decision about missing ranks and altered pipework, including whether a replica rank is warranted, is covered under Pipe Organ Restoration and Rebuilding.

Some owners will meet a different vocabulary in their own governing body’s guidance. An owner subject to guidance of that kind should read a proposal against the definitions their own governing body publishes, since under the Archdiocese of New York’s 2017 guidelines for pipe organs a project described as a rebuild means the organ’s pipes retained on a new chassis. That is that document’s own definition, used here with that attribution.

Whichever treatment is chosen, the evidence that fixes the target state comes from the instrument’s condition and its records, so the decision belongs at the condition-report and project-planning stage rather than after work has begun. How to read a condition report, how to document scope, and how to compare treatment proposals are routed from Pipe Organ Restoration and Rebuilding.
