The terroirs

Where we advise buying, and why.

An autonomous estate cannot be established just anywhere. Before the buildings, before the energy, before the water, there is the land that makes them possible. We have therefore examined France region by region, and selected five terroirs where complete autonomy is most readily achieved.

These are the criteria we apply, and what we look for in each of these regions. They apply to the territory. They never replace the examination of a particular parcel: two properties three kilometres apart may receive opposite verdicts.

The criteria

Water
This is the criterion that rules out the most regions. We look for territories where a property can hold two independent sources, each able to serve the house on its own. That calls for an accessible water table, rainfall that is regular rather than abundant, and a subsoil that stores instead of letting water run away. A region where water exists only at the mains tap will never be a Belcourt terroir.
Soil
Clay soils swell in winter and shrink in summer. On an old building, that movement opens the walls. We therefore favour limestone beds and ancient bedrock, and we require a soil survey before any offer as soon as a parcel comes close to a clay zone. It is our one rule without exception.
Climate
We look less at today's climate than at its trajectory. A terroir we retain is one whose rainfall, summer temperatures and exposure to violent episodes remain compatible with growing food and producing energy on site thirty years from now. That leads, of necessity, towards the north-western quarter and the eastern plateaux.
Buildings
Autonomy is grafted onto an architecture that accepts it. We look for regions rich in houses of character built in local stone, with outbuildings: a barn that becomes a store, a bread oven, a dovecote, separate quarters for those who keep the house. Regions of fine houses without outbuildings are set aside.
Access
An estate should be easily reached and as easily left. We retain territories served by several roads, within reasonable distance of a high-speed railway station or an airport, and we verify on the parcel that the property has two independent accesses.

The five terroirs

Normandy

Calvados and Orne

This is the most complete terroir in our classification. The Bessin and the Bocage rest on Jurassic limestone that carries old buildings well and lets water circulate, with numerous springs and rainfall spread across the whole year rather than concentrated in winter.

The building stock is outstanding: limestone manors around closed courtyards, barns, dovecotes, orchards already in place. These are ensembles conceived from the outset to live on their own resources, which considerably shortens the act of the Building.

Access is the best of all: two hours from Paris, two ferry ports towards England, several motorway routes.

What we watch for. The marls of the Pays d'Auge and certain valley floors behave differently from the plateaus. There, a soil survey is part of every Audit.

Inland Brittany

Côtes-d'Armor, Ille-et-Vilaine, Morbihan

The Breton granite bedrock is among the most stable in France for old buildings: no swelling, no shrinkage, foundations that do not move. Rainfall is generous and well spread, and the mildness of the ocean limits the extremes of both summer and winter.

Buildings of character are dense here and often underestimated: granite manor houses, logis, country manors, with substantial outbuildings.

What we watch for. Granite holds its water in fractures, in reserves that vary from one parcel to the next. Here the Audit begins with the hydrogeological survey, and harvested rainwater is sized more generously than anywhere else.

Mayenne and Anjou

Mayenne and Maine-et-Loire

This terroir holds its place through a rare balance: the qualities of the Armorican bedrock to the west, the mildness of Anjou to the east, and acquisition prices markedly below those of comparable regions.

Anjou enjoys one of the kindest climates north of the Loire, favourable to orchards, kitchen gardens and food production on site across a long season. The buildings combine the schist logis of the Mayenne with the tuffeau houses of Anjou.

Access is direct: motorways towards Paris and towards the west, and two high-speed railway stations.

What we watch for. The east of Maine-et-Loire holds localised clay soils, and summers in Anjou are growing warmer. There, a soil survey is carried out at the Audit, and we size the shading of the buildings and the summer water resource accordingly.

Burgundy and Nivernais

Yonne, Nièvre, Côte-d'Or

The limestone plateaux of Burgundy offer what we look for first: abundant and accessible water, solid foundations, and plateau or ridge positions that keep buildings above water and dry.

It is also the terroir with the most impressive buildings in our selection: fortified farms, manors, maisons de maître, often with considerable ranges of outbuildings and adjoining land.

Access is excellent towards Paris as well as towards Lyon and Switzerland.

What we watch for. The Bazois, in the centre of the Nièvre, rests on Lias marls that behave differently from the plateaus. The boundary is clear on the geological map. A soil survey is carried out before any work begins.

Jura

The first Jura plateau is the wettest terroir in our selection, with a karstic subsoil where water circulates in abundance. Plateau positions are numerous, the limestone carries well, and summer sunshine remains sufficient for substantial electricity production.

The buildings of the Franche-Comté have always been conceived to pass the winter alone: thick walls, large volumes of storage, generous roofing. Architecturally, it is the region closest to the spirit of the Belcourt Standard.

What we watch for. Karst moves quickly: what falls on the plateau reaches the water table within hours, and forest is everywhere. Here we size the waste-water treatment first, then set the distance between the house and continuous tree cover.

What we do not map

Some regions please us without appearing on the map. The Perche, for instance, meets part of our criteria without meeting them all, and we work there case by case when a property presents itself.

Conversely, superb regions are set aside without appeal: the great clay belts of the South West, lands where the water resource is already contested, and areas where continuous forest covers the whole landscape.

We would rather refuse an entire terroir than promise an autonomy the land cannot hold.

And if your estate is elsewhere?

We work everywhere in France. This map is for choosing where to buy. It does not limit the work we do. If you already have your estate, the audit will tell you what your land allows, what needs particular attention, and what it will cost.

If you are still looking, we search only in these five regions. They are the ones where we know the soil, the water and the buildings. We do not put our name to a purchase elsewhere.
