Private Residential Steel, Glulam and SIPs Roof Structure, Oxfordshire
Brief
Riteweld was appointed to deliver a complex structural package for a bespoke private residential build. The project combined structural steel, engineered timber, and modern construction methods to achieve long spans, open internal spaces, and a high-performance roof structure. Our scope included the design coordination, fabrication, and installation of structural steelwork alongside glulam beams, roof truss elements, SIPs roof panels, and associated lifting solutions. Due to the hybrid nature of the structure, careful coordination between steel, timber, and roofing systems was required throughout the design and installation process. The result is a highly engineered structural solution that supports the architectural intent while maintaining buildability, efficiency, and long-term performance.
Solution
Riteweld delivered a fully coordinated structural solution that integrated steel, engineered timber, and off-site construction methods into a single, efficient build sequence.
Structural steel roof truss frames were installed to form the primary roof structure, working in conjunction with engineered timber rafters to achieve the required spans and architectural form. This hybrid approach allowed for structural efficiency while maintaining the desired architectural intent and internal layouts.
Glulam beams were installed throughout the structure to support Posi-Joist floor systems, enabling longer spans and reducing the need for intermediate supports. This created open internal spaces while also providing clear routes for building services within the floor zone.
SIPs roof panels were used to deliver high thermal performance and rapid installation. Riteweld fabricated bespoke steel lifting plates to allow the panels to be safely lifted and accurately positioned by crane, minimising manual handling and improving installation efficiency on site.
Careful coordination between steelwork, timber elements, and roof systems was maintained throughout fabrication and installation, ensuring all components aligned correctly and the structure was delivered safely and efficiently.
