In conversation: twenty-five years of restoring listed buildings.

A long-form interview with the firm's senior development director on restraint, archival research, and the responsibility of working with inherited fabric.

The interview that follows was recorded over two afternoons at a working site in a Bloomsbury conservation area, on a Georgian terrace under partial scaffold. It has been edited for length and clarity, and the speaker has reviewed the final text. We publish it here because the senior practitioners of restoration work are not, as a rule, the practitioners who write — and the institutional knowledge they hold has a tendency to leave the trade with them.

On the first decision

The first decision on any listed building, in his telling, is not a design decision. It is the decision of how much archival work to do before any drawing is made. The cost of that work is recoverable in a single avoided mistake. The cost of skipping it tends to surface eighteen months into a programme, when the option to correct it has already closed.

On restraint

The buildings we work on outlived the people who built them. They will outlive us. The work is to leave them in a state that the next custodian can read.

The discipline of restraint, he argues, is harder to teach than any technical specification. The training programme inside the firm is built around it.

On the responsibility

The firm declines listed-building commissions roughly as often as it accepts them. The criteria for declining have not changed: a programme that does not allow for archival research, a budget that prices the surface as a finish rather than the fabric, or a brief that asks the building to perform a use it cannot accept without harm.

The full transcript will be archived in the firm's working library. We are grateful for the time.
