On the Venoge plain in the western Lausanne area, Penthaz mixes a village with growing residential districts.
Penthaz prices below the Vaud median, at CHF 7,900 per m². For a buyer that widens what one budget covers, often by a room or by a plot. For a seller it means the surrounding communes set the ceiling. A gap of 14 percent against Vaud means the same budget buys noticeably more surface here. It also means resale leans on demand spilling over from the pricier communes next door, which comes and goes with the cycle.
Position 88 of 132 in Vaud puts Penthaz 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. At CHF 8,600 per m² houses outprice flats in Penthaz by 9 percent. The difference is the plot rather than the build: a house sells with land attached, and where there is little left to build on, the land does the pricing.
Flat prices in Penthaz are up 2.7 percent over twelve months. One year is a short window: measure it against the longer trajectory before you read it as a change of direction. The district test is the harder one. Penthaz comes out 2 percent from the Gros-de-Vaud 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 Penthaz, 19 percent, dates from 1971-1980, 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.
The average home in Penthaz has 3.9 rooms for 107 m². That ratio describes the shape of local demand better than the price does: many small rooms point to family housing, fewer and larger ones to conversions and new build. The median flat in Penthaz comes out at CHF 7,900 per m², a gap of 14 percent against the Vaud median. That figure covers every flat sold, whatever the floor, the age of the building or the state of the kitchen.
The 25-year record opens at CHF 4,000 and closes at CHF 8,900, +123 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 Penthaz 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.
Lower prices in Penthaz do not make a valuation easier. The spread between properties is often wider here than in an expensive commune, which makes the commune average a weak guide to what yours is worth.
