ReSpace develop Digital Twins for the Home and Office. The built environment is going through a digital revolution and new technologies such as BIM, AR, VR, IoT and AI are transforming the industry. ReSpace is at the forefront of this development providing solutions for storage and interactive exploration, analysis, annotation and modification of BIM data, collecting all data associated with a building over its life cycle. Our system is based on a novel machine learning algorithm for spatial perception to provide an interactive and intuitive augmented reality experience. ReSpace software runs on a wide range of platforms (Microsoft MR/HoloLens, iOS/ARKit and Android/ARCore) and integrates with industry standard BIM platforms (Revit, Autodesk BIM 360, BIMobject).
