Aspects of the disclosure relate to space model generation. A computing platform may receive space program data identifying parameters of a physical space. The computing platform may load a geometry model defining a plurality of design rules. The computing platform may generate space models for the physical space based on the space program data and the geometry model. Based on the geometry model, the computing platform may produce a score for each space model. Based on the scores, the computing platform may produce a ranked list of space models. The computing platform may generate user interface data comprising the ranked list of space models. The computing platform may send the user interface data comprising the ranked list of space models, which may cause a user computing device to display a user interface including a portion of the ranked list of space models.
