What specific architectural features does your building have ?
The main house was built in the 16th and 17th centuries and the outhouse was added a century later. Both are in shell limestone, a sand-colored rock, derived from sediments left fifteen million years ago by the sea of faluns which separated the continent from the island of Armorique. Softer, and therefore easier to carve than granite (but used for door and window frames) the deposits are found south of Dinan, in the faluns region which encompasses the communes of Tréfumel, Le Quiou, Saint-Juvat and Plouasne. This limestone is either used in its natural state (known as "fine sand") and used to manufacture lime mortar, or in cut "stone gauge" and used for construction.
Places you would personally recommend
First on the list are the villages near Saint-Juvat and Tréfumel. About ten kilometers away is Léhon, a small city built on the banks of the Rance with the ancient Abbey of Saint-Magloire. A little further on is the medieval city of Dinan, fortified by Vauban. The charming port offers the chance to travel up the Rance to Saint-Malo (with its rich malouinières and parks) enjoy a thalasso, an excursion to Jersey or Guernsey, or visit the sculpted rocks of Rothéneuf, Fort la Latte and Cap Fréhel. Lovers of the seaside will be delighted by the seaside resorts of Saint-Lunaire, Saint-Jacut or Saint-Cast.
When passing through Normandy, and therefore by the bay of Mont Saint-Michel, I always stop to buy seafood at "La perle des grèves" in Saint-Benoît-des-Ondes. If I have time, I make a stop at "La Table du Marais", an excellent La Fresnais restaurant that offers seasonal cuisine made exclusively with local products.
Closer to the house, "La Vieille Auberge" in Tréfumel is simple, hearty and very reasonably priced. Truckers and craftsmen alike love to meet there for lunch. At the farm shop in Plumaudan, Bertrand Valéry offers poultry, a butcher's shop and a local delicatessen of high quality at producer prices. Coulombel Poultry in Saint-Maden makes food to order. Finally, in Saint-Pern (home to the Petites Sœurs des Pauvres) "La Ferme du Pressoir" offers the best black pudding I have ever tried, organic charcuterie and many other farm products on Wednesdays, Thursdays and Saturdays.
