NBS specifications, BIM objects, CAD downloads, CPD seminars, and dedicated project support, everything you need to specify access panels, riser doors, and hatches with confidence.
Architects specifying access panels, riser doors, loft hatches, and meter overboxes need manufacturer provided technical resources that integrate directly into their design workflow. This includes NBS specification clauses, BIM objects and Revit families, CAD drawings, fire test reports, and RIBA approved CPD seminars. A UK manufacturer who provides these resources alongside design services and dedicated technical support enables architects to specify with accuracy and confidence from RIBA Stage 2 through to Stage 5. We support architects across healthcareeducation and commercial projects, see our sector pages for compliance detail.
From NBS specifications to on site support, we provide the technical resources architects need at every RIBA stage.
