What to Keep in an Older Home, and What to Let Go

Not everything old is worth saving, and not everything new is an improvement. None of what follows depends on style or budget tier; it applies whether the room is being done on a tight number or a generous one. What changes with budget is the material, not the sequence of decisions. This is written from projects rather than from a general principle, which is why it names specific dimensions and specific failure modes rather than staying at the level of advice. Where your own room differs from the assumption behind a point, the point still applies — just adjust the number. Nothing here requires taking our word for it; each point is the kind of thing you can verify yourself on a site visit or ask a contractor to confirm in writing. That verification is usually the difference between advice that gets followed and advice that gets nodded at and ignored. A few of these points contradict what gets repeated as conventional wisdom. Where that happens we say so directly and explain why, because the conventional version is usually true in general and wrong for the specific case it gets applied to.

This matters more than it looks like it should, because the cost of getting it wrong is rarely visible until much later — usually at the point where fixing it means undoing finished work rather than changing a line on a drawing. Where any of this does carry a cost, it is usually smaller before installation than after. A change raised at the drawing stage is a line on a plan; the same change raised after the trades that depend on it have moved past it is a demolition and a delay. Most of what follows needs deciding before the trade it depends on starts, not before the project starts — so there is usually more time to get this right than it first appears, provided the decision does not get skipped until that trade is already on site.

Keep original timber doors and windows if they are sound

Old-growth hardwood joinery is usually better than anything you can buy now. Reglazing and reconditioning is almost always cheaper and better than replacing.

Keep terrazzo and old stone floors

Mosaic and terrazzo can be ground and polished back to excellent condition for far less than a new floor, and they are irreplaceable in character.

Replace the wiring, without exception

Any installation over about twenty-five years old is a safety item, not an aesthetic one. This is the least glamorous and most important line in an old-home budget.

Replace galvanised plumbing while walls are open

GI corrodes internally and restricts flow. Doing it later means opening finished walls.

Be honest about single glazing and comfort

Original windows are worth keeping for character, but in a noisy or very hot location, secondary glazing behind them is what makes the room usable.
