Old houses have opinions. Anyone who has lived in one knows this. The rooms are smaller. The ceilings sit where they sit. The floors slope a little, and the plaster has texture you cannot buy at a store. Fighting these traits almost never works. The best interiors in older homes start by listening to the house.
South Florida has more of this housing stock than people expect. West Palm Beach alone holds several historic districts full of 1920s Mediterranean Revival homes. El Cid, Flamingo Park, and Grandview Heights are the best known. These houses were built with separate, purpose-driven rooms. A parlor here, a dining room there, a kitchen tucked in back. That layout feels foreign to buyers raised on open plans.
So what do you do with a house like that? The short answer: less than you think. Original wood floors can usually be sanded and refinished. True plaster walls carry depth that drywall cannot match. Arched openings and old trim profiles give a room its character for free. Designers who work in these districts tend to keep those elements and rebuild everything behind them.
The firms that do this well treat each house as its own brief. One example worth reading comes from a design-build team that handles interior design work in West Palm Beach across both historic and post-war homes. Their approach sorts houses by era first. A 1925 house gets a different lighting plan, paint sheen, and millwork strategy than a 1955 ranch. That sounds obvious. It is also rare.
There is a practical side to all this, too. Homes built before 1978 may contain lead-based paint. The EPA’s lead program sets rules for how renovation work in those homes must be handled. Certified contractors follow set containment and cleanup practices during the job. It is one more reason older homes reward professional planning over weekend guesswork.
Mid-century houses bring their own lessons. Many hide original terrazzo under decades of carpet. Grinding and polishing that terrazzo often beats any new floor you could put over it. Low ceilings call for flush light fixtures and furniture with a lower profile. Closed kitchens can open up, but only where the structure allows it.
The thread running through all of this is restraint. A century-old house does not need a new personality. It needs a good edit. Keep what the house does well. Fix what it does poorly. Let the age show where the age is the point. The result reads as one coherent home rather than a new interior wearing an old shell.
That is the real lesson these houses teach. Good design is not about imposing a look. It is about knowing what to leave alone.
