The average price recorded in Trégastel stands at 4 693 €/m². That level, high for a municipality of fewer than 2 600 inhabitants, owes to its seafront position on the Côte de Granit Rose and to the nature of the market: according to INSEE, the French national statistics institute, second homes make up close to half of the housing stock. Demand therefore comes largely from buyers looking for a holiday house or apartment, often near the beaches, rather than for a home to live in year-round. The average covers varied situations: a villa with a sea view, a house in the village centre and an apartment in the second row do not belong to the same segment. The figures come from the DVF database, which records sales actually registered before notaries.

The Trégastel market is first of all a market of seaside second homes, which sets it apart from municipalities geared to local employment. Demand depends on the wish to own a holiday property on the Côte de Granit Rose and on the purchasing power of households from other regions, more than on the working-age population of the municipality. That structure explains price levels above those of many inland municipalities in the department, and strong competition for properties close to the beaches and enjoying a sea view.
Two factors will weigh on the coming years. On one side, the scarcity of building land along the shore, reinforced by the Coastal Act, limits new supply and supports the price of existing properties. On the other, the second-home market remains sensitive to the economic climate, to credit conditions and to changes in local taxation on dwellings that are not main residences. The energy renovation of older houses exposed to the sea climate is also becoming an ever more present bargaining point.
A seaside resort on the Côte de Granit Rose, Trégastel compares first of all with its immediate neighbour Perros-Guirec, the other tourist hub on this coast. The gap is wider with Lannion, a sub-prefecture town geared to employment and services, whose market follows the logic of permanent residents rather than of holiday homes.
The territory of Trégastel has been occupied for a very long time: it preserves several prehistoric remains, among them the gallery graves of Kergüntuil and of the île Renote, a dolmen and standing stones. The parish belongs historically to the Trégor, in the north of Brittany, and long lived off farming, inshore fishing and the working of the local granite, that pink rock more than three hundred million years old which gives the coast its name. Quarrymen drew from it paving stones and dressed stone shipped out by sea.
From the end of the 19th century, and above all during the 20th century, Trégastel turned towards seaside tourism, like its neighbour Perros-Guirec. The granite chaos of Coz-Pors and of the Grève Blanche, the fine sand beaches and the sentier des douaniers coastal path that skirts the île Renote drew a holiday clientele, and villas were built facing the sea. The marine aquarium, laid out beneath the rocks and opened to the public from 1967, completed what the resort had to offer. That tourist calling, in place over several generations, still shapes the structure of the property market in the municipality.
According to INSEE, the French national statistics institute, Trégastel has around 2 500 inhabitants for a housing stock of which close to half are second homes, one of the highest proportions in the department. The permanent population is markedly older than average, with a large share of retired people settled year-round. In the summer season the population of the municipality multiplies several times over, which weighs on demand for holiday housing. Buyers are therefore mostly households from other regions, looking for a second home by the sea or a pied-à-terre for retirement, alongside a minority of permanent residents, working people from the Lannion area and the Côte de Granit Rose or local first-time buyers.
The average price recorded is 4 693 €/m², calculated from the transactions registered by notaries and published in the DVF database. It is a municipal average, which pools very different properties: a villa near the beaches, a house in the village centre and an apartment set back from the sea do not sit at the same level. The sea view, the condition of the property and the distance to the shore explain a good share of the gaps observed.
Trégastel is a seaside resort set at the heart of the Côte de Granit Rose, a sought-after coastline where the supply of land and of seafront property is limited. The strong presence of second homes, noted by INSEE, sustains demand from across France for a narrow holiday market. That combination of scarce coastal land and tourist appeal supports levels above those of comparable municipalities located inland.
The stock is largely dominated by houses, among them many villas and holiday builds spread from the village centre to the edge of the beaches. Apartments do exist but remain more limited in supply, often in small blocks close to the seafront. The choice depends on the plan: a year-round home, a holiday second home or a seasonal rental investment do not lead to the same properties or the same sectors of the municipality.
Largely so. The population of the municipality multiplies several times over in summer, and close to one dwelling in two is a second home according to INSEE. Buying demand follows that holiday logic, with buyers often from outside the region. This makes the market sensitive to the state of the second-home market and to the purchasing power of households investing in a leisure property, more than to local employment.
On a coastline, several points deserve attention: exposure to wind and sea spray, the condition of the joinery and the roof on an older property, and any classification of the plot in the areas governed by the Coastal Act, which strictly frames building near the shore. The energy performance survey matters on a stock that is sometimes old and damp. Finally, for a seasonal letting project, you should check the municipal rules that apply to furnished tourist rentals.
