TETHION

About TETHION

Tethion is a specialist consultancy operating at the intersection of statutory compliance, fire safety, and coordinated project delivery. Rooted in architectural technology, we fuse design, engineering, and regulation into coherent, compliant outcomes. Our name draws from the fire tetrahedron, symbolising our role as the catalyst, the element that brings architecture, structure, building services, and wider specialisms together under robust oversight. Founded by Hassan Ahmed, a chartered architectural technologist and fire safety professional with over 17 years’ experience, Tethion has led complex, higher-risk projects including hospitals, residential towers, and large-scale refurbishments where buildability, fire safety, and statutory duties must align from the outset. What sets us apart? • We bring a designer’s understanding to a regulator’s role, balancing practical buildability with the functional requirements of the Building Regulations. • We operate at the intersection of compliance and delivery, embedding regulation into design as an enabler, not a constraint. • We lead with clarity, structure, and accountability, guiding teams through the new safety regime. Core services: • Building Regulations Principal Designer (HRB & non-HRB) • BSA Client Advisor • Fire Safety Consultancy • CDM Principal Designer & Client Advisor • Technical review & design audit • CPD delivery and coaching We provide clarity where disciplines meet, structure where compliance is complex, and confidence where safety is critical, helping teams design with intent, coordinate with clarity, build with confidence, and comply through Tethion.
