HOME / DOUBLE STOREY EXTENSIONS
Double storey extensions are larger structural projects that add additional floor space to both the ground and first floors of a property.
Because these extensions introduce significant structural loads, Building Regulation drawings and structural calculations are usually required to demonstrate that the structure safely supports the loads created by the extension.
BuildRegs prepares structural calculations and Building Regulation drawings for double storey extension projects across the UK.
If you already have architect drawings prepared, you can upload them for review and receive a fixed quote for the documentation required for Building Control submission.
Typical double storey extension projects start from £899.

Double storey extensions often involve structural alterations to the existing property as well as the construction of a new two-storey structure.
Structural calculations demonstrate that the extension safely supports the loads created by:
These calculations are commonly required by Building Control to confirm that the proposed structure meets structural safety requirements.
BuildRegs prepares structural calculations that clearly demonstrate the structural design of the extension.
Many extension projects involve creating a large opening between the existing house and the new extension.
This opening often requires a structural steel beam to support the loads from the upper floor and roof.
Structural calculations determine the correct beam size and confirm that the beam safely supports the loads from the building above.
These calculations form part of the documentation submitted to Building Control.
Building Regulation drawings show how the extension will be constructed in accordance with Building Regulations.
These drawings typically include technical details relating to:
Building Regulation drawings help Building Control understand how the proposed extension complies with technical construction standards.
