What Jan Hird Pokorny Associates, Inc. does

Jan Hird Pokorny Associates, Inc. (JHPA) is a New York-based historic preservation architecture firm founded in 1946 by Jan Hird Pokorny, FAIA. The firm operates through two integrated entities: JHPA, Inc., which provides preservation consulting, condition assessments, building materials forensics, existing condition surveys, historic structure reports, master planning, materials conservation, drone surveys, and regulatory assistance (including NYC Landmarks Commission approvals and grant/tax credit support); and JHPArchitects, PC, which delivers architecture, planning, and preservation design services spanning restoration design, period-appropriate additions, historic interiors, construction documents, and construction administration. The firm serves a diverse client base of museums and historic house trusts, government agencies at city, state, and federal levels, religious institutions, private clubs, and private owners of landmarked properties, with a geographic focus on the Northeast US. JHPA's core differentiator is deep, decades-long expertise in historic preservation, including pre-Colonial Dutch and English wood-frame building techniques, supported by an in-house licensed drone operator, advanced degrees in preservation among staff, and a portfolio of 40+ industry awards spanning three decades.

The firm generates revenue through project-based professional services fees billed by both entities—consulting fees for assessment and forensics work, and architectural design fees for restoration and adaptive reuse projects. Go-to-market is primarily relationship-driven, with new business sourced through professional reputation, awards recognition, repeat clients, and referrals within the historic preservation community. The firm maintains a content-driven website portfolio and an active Instagram presence (@jhpa_ny) for top-of-funnel visibility. Leadership is currently anchored by principals Michael Devonshire (Director of Conservation) and Carl Pucci, FAIA (Director of Architecture), following the founder's death in 2008. The firm is privately held, with no parent company, no funding rounds, and no public listing. Following the founder's passing, no acquisition, IPO, or ownership transition has been disclosed; the firm continues to operate as an independent, closely held professional practice.
