Sea-view villa prices per square metre along Lazio’s coast vary considerably by location and specification, but serious buyers should budget from around €3,000 to €6,000 per square metre for quality coastal properties, with prime positions in sought-after towns pushing well beyond that. National averages of roughly €2,200 per square metre reflect the broader Italian market and do not apply to premium coastal stock. Finished villas with genuine sea views in desirable coastal towns command a significant premium over inland equivalents.
