Brownstone renovations: preserving character while modernizing systems
Original moldings and a century-old shell can coexist with modern wiring and central air. How we renovate a brownstone without erasing what made you buy it.
People buy a brownstone for what a hundred years gave it — the moldings, the proportions, the light. A good renovation modernizes the building without arguing with any of that.
Survey what's worth keeping
Before any demolition, we document original millwork, plaster detail, and structural timber that's worth preserving or restoring, so decisions about what stays are deliberate, not accidental.
Modern systems, invisible install
Central air, updated electrical, and modern insulation can all go in through careful chase and cavity planning that keeps ceiling heights, moldings, and sightlines intact — it just takes more planning than a new-construction install.
Structural realities of old timber-frame buildings
Century-old joists and masonry don't behave like modern lumber and CMU. We evaluate the existing structure early so reinforcement is planned, not discovered mid-demolition.
