Perhaps you would be able to help me with a structural problem that is facing one of my projects. The proposal is for a loft room in a large house with a steep high roof. The space is ideal, but the structure is not. The existing loft floor, which will have to be strengthened, is supported near the centre of the house by the brick internal walls which reach up into the loft. At the outside edge of the house the roof drops down into the rooms below and the loft floor is fixed not to the walls, which are further out, but to the rafters. So the loft floor is smaller than the floor below. Imagine a shoe box with a lid that is smaller than the box – the lid is supported at the centre, but the edges float (or rather are fixed to the roof in the real house). I want to strengthen the floor and support new walls and loads right to the edges. there must be many houses like this. What would your recommendation be?
