On the hillsides above Nyon, Trélex combines a La Côte village with a direct link to the lakeside.
The village, on the Nyon-Saint-Cergue line, mixes older houses and districts of family villas in a setting of vines and forests. The closeness of Nyon and its station brings every service within a few minutes.
The view of Lake Geneva and the quick access to Geneva support demand from families and commuters. Villas with an open outlook gain good value, in a La Côte market where supply stays limited.
Over the past 25 years, the price per square metre of a flat in Trélex has gone from around CHF 4 400 to CHF 10 300, a change of +134 %. Over the last twelve months, the trend is +1,2 %.
These figures track the local market over time. They point to a trend, they do not replace the valuation of a specific property, which depends on its condition, its floor and its view.
