When the depth of a building's foundation is measured to ensure a first floor extension can be built on is the brick that sits on the footing included or the concrete footing just measured? I always assumed it was just the concrete footing?
The type of soil we have is reasonably thick clay and I am planning on having a first floor timber frame extension added on top of brick structure so just wondering how deep my foundations need to be.
