Overview

This project involved the conversion of an existing agricultural barn into a high-specification live-work unit under Class Q permitted development rights. Our involvement began at the feasibility stage, where we provided the essential structural report to determine that the building conformed with planning requirements for conversion.

The challenge

The primary hurdle was proving to the planning authority that the existing structure was capable of conversion without exceeding the 'permitted development' criteria. Once planning was secured, the focus shifted to creating a contemporary live-work space within the original shell. This required a design that could support a new curved roof and modern floor loads without over-stressing the original agricultural frame.

The structural strategy

Our strategy involved designing a completely independent timber frame internally to the barn. This 'structure within a structure' allowed us to achieve the ambitious curved roof profile while ensuring the building met modern thermal and structural standards. We specified a traditional strip foundation solution and a suspended beam-and-block floor to provide a robust, level base for the new living and working zones. This approach ensured that the new loads were handled entirely by the new timber frame, protecting the character of the original barn while delivering a high-performance modern interior.

Outcome

The result is a highly functional building that combines a sleek, modern silhouette with a traditional agricultural footprint. By providing both the initial Class Q assessment and the detailed structural design, we gave the client a seamless path from planning approval to a buildable, high-quality architectural home.
