What is a flood loft (waterzolder)?
A flood loft, in Dutch “waterzolder”, is a loft in a farmhouse that could be turned into a stable when the land flooded. Part of the loft floor is specially strengthened so it can temporarily carry the weight of livestock. A hinged section of the floor could be lowered as a gangway or ramp, so the animals could be led upstairs.
Why a flood loft?
In low-lying river areas of the Netherlands, the land flooded regularly. Farmers had several ways to keep people and animals dry: building on a raised mound (terp), putting up a separate flood barn on higher ground, or creating a flood loft in the farmhouse itself. The flood loft had the advantage that no extra building was needed and the livestock stayed close by.
Construction
- A strengthened floor area: heavier or additional joists, or extra support beneath, because animals impose much higher point loads than hay.
- A drop-down floor section as access for the animals.
Restoration and conversion
When converting such a farmhouse into a home, it is tempting to remove or alter the heavy joists. Tips:
- Have the floor structure assessed by a structural engineer first; rot and insect attack in old joist ends built into the walls are common.
- Record special details, such as the hatch, before changing anything.
- Check the listing status: changes to the structure of a listed building need consent.
