Many extension projects involve structural alterations to the existing house. For example, when a rear extension is built, the wall between the existing house and the new extension is often removed to create an open-plan living space.
This usually requires the installation of a structural steel beam to support the loads previously carried by the wall.
Structural calculations demonstrate that the beam and supporting structure safely support those loads. These calculations are typically submitted to Building Control as part of the Building Regulations approval process.
BuildRegs prepares structural calculations that clearly demonstrate the structural design of the proposed extension.
Every extension project is different, but structural calculations are commonly required for:
These calculations confirm that the structure safely supports the loads created by the extension.
