Structural design
Structural design and calculations are a key part of most residential building projects, ensuring that proposed works are safe, stable and compliant with Building Regulations. They are commonly required for extensions, loft conversions, structural alterations and property conversions.
At HOBBS ARC, we coordinate structural design and calculations as part of a clear, practical package that supports both Building Regulations approval and construction on site. Calculations are prepared to demonstrate how loads are carried through the structure and how new elements interact with the existing building.
Our focus is on clarity and buildability, helping homeowners and builders understand what is required and reducing delays during approval and construction.
What’s included
Structural design and calculations are tailored to the specific project and typically include:
-
Structural calculations prepared for Building Regulations approval
-
Design of key structural elements such as beams, lintels and openings
-
Load paths and assumptions clearly set out
-
Information coordinated with Building Regulations drawings
-
Documentation suitable for submission to building control
Where required, structural details are integrated into the wider technical drawing set to ensure consistency across the project.
How we work
Structural design is normally developed once the layout and scope of works are agreed. In many cases, a site survey is required to confirm existing construction and gather any missing information needed for accurate calculations.
Structural calculations are prepared based on the approved design information and coordinated with the Building Regulations drawings. Once complete, the information is issued for submission to building control and can be used by builders during construction to ensure works are carried out as intended.
