Buchillon lies on Lake Geneva between Saint-Prex and Allaman, a small La Côte village that also borders Etoy.
At CHF 10,500 per m² for a flat, Buchillon sits in the upper band of the Vaud market. That level usually goes with scarce building land and few sales, so a valuation rests on a thin set of comparables. A gap of 33 percent over the Vaud median is not statistical noise. It measures what buyers accept to pay for the location itself, and it holds through the cycle instead of appearing in one strong year.
Out of 272 communes measured in Vaud, Buchillon sits at position 52. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average. Houses carry a premium of 30 percent per square metre over flats in Buchillon, CHF 13,600 against CHF 10,500. Households buying a house here are mostly trading up from a flat nearby, so demand holds even when volumes drop.
The last twelve months added 2.7 percent in Buchillon. Rises of this order usually come from a shortage of listings rather than from a wave of new buyers, and they unwind faster than they build. Against the Morges district the gap comes to 18 percent. This is the comparison that carries weight for an estimate, because communes in one district share a labour market, a transport network and the same pool of buyers. 1971-1980 accounts for 15 percent of homes in Buchillon, ahead of the other periods without dominating them. A mixed stock widens the price range inside one commune, where two flats of the same size can be a third apart on condition alone.
At 4.6 rooms and 148 m² on average, homes in Buchillon are sized for households rather than single occupants. If you are looking for a studio or a two-room flat, expect a thinner choice and less room to negotiate. CHF 10,500 per m² is the working reference for a flat in Buchillon, 33 percent from Vaud. Take it as a starting point. In a commune this size, the spread between the cheapest and the dearest street is often wider than the gap to the canton.
The 25-year record opens at CHF 3,800 and closes at CHF 9,700, +155 percent apart. Use it to sanity-check an estimate rather than to project forward, since nothing in the series promises the next decade repeats it. Transaction volume in Buchillon is high enough that one unusual sale does not distort the medians. That matters, because thin markets are where automated estimates go furthest wrong and where a local opinion earns its keep.
In Buchillon the difference between two flats on the same street can run into six figures. Getting your own number, rather than reading the commune median, is what makes that difference visible before you set a price.
