We introduce Generative Twins (GT), a workflow that shifts digital twin creation from explicit geometric reconstruction toward probabilistic 3D synthesis. The pipeline takes a\r\nsingle street-level façade photograph, corrects perspective distortion and removes occlusions, uses an instruction-conditioned multimodal image model to synthesise an isometric view of the building, and passes that view to an image-to-3D reconstruction model that leverages learned shape priors to produce a textured mesh without manual modelling. Three image to-3D platforms (Hitem3D, Hyper3D and Hunyuan3D 3.1) are compared on identical isometric inputs and assessed on architectural boundary clarity. We demonstrate GT through two applied cases: (i) reconstruction of ordinary residential streets in Detmold as stimuli for a virtual-reality study of multi sensory urban perception, and (ii) Green Editor, a design-exploration tool in which façade greenery is added or removed at the image layer before mesh generation.\r\nTogether these cases position Generative Twins as a scalable pathway for the digitization of ordinary building stock, with emphasis on controllability, editability, and iterative design workflows."}],"_id":"14070","publication_status":"published","keyword":["Digital Twins","Virtual Reality (VR","Artificial Intelligence (AI)","Image-to-3D","Generative Design."],"conference":{"start_date":"2026-09-07","end_date":"2026-09-11","name":"44. eCAADe-Konferenz","location":"Lübeck"},"publisher":"eCAADe","volume":1,"status":"public","date_created":"2026-09-30T10:14:15Z","type":"conference_editor_article","year":"2026","citation":{"havard":"M.K.
