A neighbour of Sion between plain and hillside, Conthey combines a large retail zone, vineyards and tiered villages towards the Alps.
At CHF 5,800 per m², Conthey sits near the middle of the Valais scale. Which side of that median your own flat lands on depends more on floor, view and condition than on the address itself. Paying 5 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 24 of 67 in Valais puts Conthey 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. A house in Conthey is valued around CHF 6,500 per m² against CHF 5,800 for a flat, a gap of 12 percent. Land is what separates the two figures, and the scarcer the building plots, the wider that gap runs.
The last twelve months added 4.1 percent in Conthey. 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. The district test is the harder one. Conthey comes out 2 percent from the Conthey median, measured against communes competing for the same buyers rather than against a whole canton with several markets in it. The largest group of homes in Conthey, 19 percent, dates from before 1919, with the rest spread across the other bands. Where stock is this varied, a commune price per m² carries less weight and the comparison has to come down to buildings of the same age.
Average size in Conthey is 103 m² across 3.6 rooms. Compare your own property with that figure before you read any price per square metre: an outsized home rarely sells at the local rate, and a small one often beats it. CHF 5,800 per m² is the working reference for a flat in Conthey, 5 percent from Valais. 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.
From CHF 3,700 to CHF 7,700 per square metre in 25 years, +108 percent in all. The path was not a straight line, and the flat or falling stretches inside it are precisely what a long average hides. Transaction volume in Conthey 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. If you are weighing a sale in Conthey, the useful question is not the commune price but yours. A few minutes and a handful of characteristics are enough to place your property inside the local range.

Count on roughly CHF 6,500 per m² for a house in Conthey. That rate applies to habitable surface, which leaves out the garage, the cellar and any unconverted attic, all of which add value but never at the same rate.
The dominant band in Conthey is before 1919, which covers 19 percent of homes. Average size runs to 3.6 rooms, so the commune is built mainly for households rather than for single occupants or short stays.
