What are the requirements for a foundation for a wooden house? They are nothing specials, i.e., not very different from the requirements for a traditional brick & mortar house foundation. A wooden house is lighter, but we don’t think that makes a lot of difference for the foundation itself. For us, as wooden house builders, there are three requirements: the foundation should be flat, it should let us anchor the house firmly, and the pipes and guides for water and electricity should be at the exact right spot.
Contrary to popular belief, wooden houses have a very high life expectancy. Of course wood should be protected from humidity, but if the owner takes care of his house it will last very long. When designing a wooden house we make sure that water can always escape from the house and that walls are ventilated. What would then be life expectancy of a wooden house? We have several examples of old wooden houses in Europe.
