Measurements of the substructure Size of the substructure Now that we know the size of the oven floor and the shape of the vault, we can calculate the measurements of the substructure: For the length we need the sum of: the thickness of the wall of the oven mouth (approx. 20 cm) + the length of the oven floor + the thickness of the vault ( approx. 20 cm) + the thickness of the insulation layer ( approx. 10 cm) + if necessary, the thickness of the outer wall ( approx. 20 cm), depending on if you close the rear side or not For the width we need the sum of: 2 x the thickness of the outer wall ( 2 x approx. 10-20 cm) + The width of the oven floor + 2 x the thickness of the vault ( 2 x approx. 20 cm) + 2 x the thickness of the insulation layer (2 x approx. 10 cm) + 2 x open space of minimally 1 cm between loam layer and outer wall Working height of the substructure The working height is equal to the height of the substructure plus the thickness of the oven floor. Usually it is between 80 cm...

Haf-timbered barn at the Tommenmolen Since when was there a barn on this spot? The mill building dates from the 16th century, but we do not know exactly when the first barn was built. The Ferraris map (late 18th century) shows for the first time a building on the exact site of the current barn. The barn is clearly depicted on maps and land register plans of the 19th century. What did the original barn look like? We know this thanks to paintings, etchings and photographs from the first half of the 20th century. It was a half-timbered barn with a thatched or straw roof. However, that barn has disappeared, perhaps in the late 1940s, early 1950s, presumably after a fire. Current half-timbered barn Until 1977, the current barn stood on a yard on Veldkant street, about 500 meters from the Tommenmolen. At the initiative of the municipal council of Grimbergen and with the help of the Bokrijk open-air museum, the barn was fully measured, photographed and dismantled. The wooden framework went to Bokrijk for restoration...
