Historic homes get bought for their character — original trim, plaster details, proportions you can’t replicate in new construction — but that same character is exactly what’s at risk during a poorly planned renovation.
Start by identifying, room by room, what’s genuinely original and worth preserving versus what’s a later, less significant addition or alteration. Not every original element needs to survive a renovation, but that decision should be deliberate, not accidental demolition.
Original millwork, trim profiles, and door and window casings are often worth preserving and restoring rather than replacing, even when the rest of a room is being substantially updated — they’re usually the hardest and most expensive details to replicate well if lost.
Where modern systems need to be introduced — updated electrical, HVAC, insulation — plan the routing carefully to minimize damage to original plaster, trim, and flooring. This takes more careful planning than a typical renovation, but it’s far less expensive than repairing avoidable damage to original details after the fact.
For additions or significant alterations, matching the original home’s proportions, materials, and architectural details — rather than introducing a jarringly different style — keeps a renovated historic home feeling like a continuation of its original character rather than a mismatched patchwork.
