TRIARCH, Inc.

Located in a turn of the century loft building in the TriBeCa neighborhood of lower Manhattan, our office numbers between five and eight people depending on our workload. Our work is a collaborative effort between the principals, the staff, the client, the consultants and the contractors.

The principals of TRIARCH, Stephen Corelli and Michaela Deiss, began working together in 1987 in partnership as CORELLI/DEISS. While our work includes some retail and office projects, our primary focus has been residential – from pre-war apartments to loft renovations, townhouses and historic restoration. We are comfortable with, and are challenged by, work across a wide stylistic spectrum – from the restoration of an eighteenth century house to a modern loft renovation. Whatever the project, we try to find the most appropriate functional, aesthetic and cost effective response.
