Built in the 19th century, the Grand Boulay has been a farm up to 1975. There was a big kitchen garden in front of the house, and in the back ground an orchard. The pond was small. The courtyard was occupied by the agricultural machines, the rabbits and a stock of beetroots.
The house is abandoned, the kitchen garden and the orchard are transformed into feed.

In the 1980s, the property became a golf practice. The owners encircled it with thuyas, poplars, a big wooded hedge, with a pine forest (black kindling of pines of Austria), of two oaks, two beautiful cedars and a red maple.

Arrived in November 1992, Henri bought the property in July 1993.
Then he started to make new plantations :
Winter, 1993 : Plantation of the new Orchard, the small chestnut grove (forest of common species châtaignés, birches, charms, ash trees), walnuts and acacias.
1994 : Plantation of the first collection trees (Liquidambar, Ginkgo Biloba, Tulip tree of Virginia, weeping Sophora, Albizzia).
1996 : Creation of the massifs of the Closed garden and the Mediterranean Massif.
1997 : Creation of the Massif of the Barrier and the Massif of Pumpkins, Development of the garden around the old well.
1998 : Patricia has been joining Henri : they share the same passion for the garden.
The lake is redrawn, put in water, lines and strews with water plants.

2007 : Creation of a Dry Garden. First opening of our garden to our friends. We settled the pond in the rose garden and create the labyrinth of Bamboo.

On 2008 : The decision is taken to reorganize the courtyard, with for the first time the assistance of a landscape architect, Anne-Mie AERTS. The works will spread out all over the year.
