Proposed Loft Addition

Project Details

This project involves the structural analysis and design for a proposed addition to an existing residential dwelling. The scope of work includes the design of timber studs, floor framing, and roof rafters to accommodate a new loft conversion and house extension. The structural framework utilizes a combination of C24 graded timber for joists and rafters alongside structural steel elements, including UKB and UKC beams, to provide robust support for the new configurations.

The engineering process included a comprehensive loading analysis to ensure the structure meets safety standards for dead, imposed, snow, and wind loads. All structural members were designed in accordance with Building Regulations and Eurocodes, specifically BS EN 1991 for general actions and BS EN 1995 for timber design, ensuring long-term stability and serviceability. For the substructure, trench fill or strip foundations were specified to reach a minimum depth of 1000mm below ground level, providing a stable base for the new masonry and timber loads. Detailed attention was given to structural connections, such as beam-to-beam junctions and lateral restraint strapping, to optimize the building’s overall resilience against environmental forces.

Role

Structural Engineer/Designer

Services Provided

Structural engineering services include the preparation of comprehensive structural calculations, consisting of loading analyses for wind, snow, dead, and live loads, as well as detailed structural analysis and design calculations for all structural components. The scope also includes the development of structural drawings, such as loft floor framing plans, roof framing plans, structural sections, and all necessary structural details, notes, and specifications required to support the design.
