Nicknamed the golden hill, Cologny overlooks the bay with the most spectacular views in the canton and an exceptional residential market.
At CHF 17,000 per m² for a flat, Cologny sits in the upper band of the Geneva market. That level usually goes with scarce building land and few sales, so a valuation rests on a thin set of comparables. Over 2 years, 221 property sales in Cologny completed and were registered. Half went above a total price of CHF 2,540,000 and half below. Asking prices sit higher, since they still include everything buyers negotiated away.
Paying 44 percent more than the cantonal median buys location, not floor space. The same budget moved to a neighbouring commune would typically add a room, and that is the trade most buyers here have already made. Position 1 of 45 in Geneva puts Cologny among communes with similar price levels and often very different housing stock. Two communes can share a rank and still value the same flat differently once age and condition are taken in.
Houses carry a premium of 26 percent per square metre over flats in Cologny, CHF 21,400 against CHF 17,000. Households buying a house here are mostly trading up from a flat nearby, so demand holds even when volumes drop. Up 2.4 percent in a year, Cologny has been priced by whoever was willing to pay most for a small number of properties. In a commune with few sales, that is exactly how a median gets moved. 224 properties are currently on the market in Cologny. Supply at that level decides how long a sale takes, because the more listings compete, the more the first serious offer sets the reference for the rest.

A mixed stock widens the price range inside one commune: two flats of the same size can be a third apart on condition alone. At 4.6 rooms and 162 m² on average, homes in Cologny 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.
Over 25 years the median moved from CHF 3,700 to CHF 10,300 per m², a change of +178 percent. That is the market, not your property: a flat renovated in the meantime followed a different curve entirely. In Cologny 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.
