The house is a steel frame structure with engineered timber floor joists, the engineered joists allow for services to be distributed easily throughout the house. The ground floor is a suspended precast concrete plank floor, precast planks were chosen to limit the number of subfloor masonry walls required, which would affect the flow of the floodwater within the flood void.
As the building is within a flood plain, within the subfloor masonry we have a number of openings to allow for the free flow of floodwater through the subfloor void.
With our experience of SuDS, we were able to design voids around and underneath the building so water would be able to run freely under the building – alleviating any flood concerns. The ground level of the building is above the highest anticipated level of water so there is no risk to the homeowner.
This is a reasonably new flood-resistant technology but SWJ Consulting have used this method on several projects to great effect and we consider it a good way of avoiding the expense of stilts.
