Historic restoration
Survey, documentation, dismantling strategy, material conservation, action repair, pipework repair and evidence-led reinstatement.

Build for the room that will answer back.
House of Resonance builds, restores and voices pipe organs as complete instruments: wind, action, pipework, case, tuning and the acoustic space that joins them together.
NEW INSTRUMENTS
Designed from first acoustic survey
RESTORATION
Conservation-led, mechanically honest
VOICING & CARE
Room, season and repertoire considered
About / instrument before object
An organ is architecture that has to breathe on command.
Wind pressure, scaling, speech, temperament, action geometry and room absorption all shape the result. We design those relationships together instead of treating the pipe façade as the project.
Historic work begins with documentation and restraint. Parts are repaired before replaced when their continued service is technically responsible and materially honest.
Offerings / workshop book
New instruments
From room study to final regulation.
Case design, wind system, action, tonal scheme, pipe scaling, workshop build, installation and final voicing are developed as one commission.
Tonal finishing
Rebalancing speech, attack, power and blend when an instrument is mechanically sound but acoustically unsettled.
Planned maintenance
Tuning, seasonal checks, leather/action inspection, fault logs and intervention planning before emergency failures become normal.
Process / voicing ledger
A stop list is a promise. Voicing determines whether it is true.
Open Diapason 8'
Foundation
Scale and speech set for room support rather than solo prominence.
Stopped Flute 8'
Colour
Warm low-pressure voice for accompaniment and intimate registrations.
Principal 4'
Chorus
Carries definition through the nave without hardening the upper work.
Trumpet 8'
Reed
Revoiced for authority at distance while retaining stable speech at low temperature.
Projects / instrument 46
St. Alden's: clarity without glare.
A fictional 28-stop instrument for a long, hard-surfaced church where the old organ projected loudly but failed to articulate ensemble detail. The new scheme reduced wind pressure, broadened foundation tone and reserved brilliance for the upper chorus.

Proof / listening notes
Results that are heard, then documented.
Choir support
Accompaniment registrations now retain vocal definition at the rear third of the nave without added loudness.
Tuning stability
Post-restoration wind leaks fell sharply and seasonal tuning visits reduced from five reactive callouts to two planned visits.
Repertoire range
The rebuilt chorus supports early contrapuntal work and late-romantic colour without relying on one dominant tonal family.

Insights / voicing notes
Loudness cannot repair weak speech
A pipe that starts poorly will not become more articulate simply by receiving more wind. Attack, languid geometry and mouth treatment matter first.
The room is part of the stop
An 8-foot principal that feels balanced in the workshop can bloom excessively in a reflective nave. Final voicing belongs on site.
Restoration requires a stopping rule
The goal is not to make an old organ behave like a new one. Repair until reliability and musical function return without erasing material evidence.
FAQ / before dismantling
Can you modernise an historic organ discreetly?+
Sometimes, but the case for change must be technical and musical. Reversible interventions are preferred where historic material is significant.
How long does restoration take?+
A survey comes first. Scope can range from targeted action repair over weeks to complete workshop restoration over many months.
Do you maintain organs you did not build?+
Yes, after an initial condition survey establishes the instrument's state, known alterations and immediate risks.
Can you quote from photographs?+
Only at a very preliminary level. Mechanical access, wind condition, pipework, acoustic response and documentation need an on-site survey for a responsible scope.
Contact / acoustic & condition survey
Before we touch a pipe, we listen to the room.
Send the instrument location, builder/date if known, current concerns, recent work and the musical role the organ must serve.
