Presold homes refer to houses that are sold before construction has begun or while the construction is still underway. To facilitate the selection and purchase of houses by clients, construction companies usually use sample houses, models, or videos to show the appearance of new houses being constructed. Clients have numerous opportunities to participate in the spatial planning and spatial allocation of the houses because these houses have not yet been constructed, and clients can direct the style and materials used for interior partition walls and furnishings. However, when discussing housing styles with their clients, construction companies often depend on their imagination to create three-dimensional images depicting the interior layout of houses. Construction companies can neither immediately present new styles when clients request changes to partition walls or styles nor estimate the costs of the changes. Consequently, clients cannot immediately decide on such changes, which then leads to poor communication between the two parties. Accordingly, this study designed a system that integrates building information modeling (BIM) and virtual reality (VR). Through this system, clients can change and immediately view house styles in immersive VR and decide on whether the changes meet their demands. Furthermore, the designed system is linked to a unit price database for materials. When clients make alterations in the system, it automatically calculates the costs of the changes and then helps the client determine whether the changes are within their budgets. The results of this study indicate that the designed system can accurately and rapidly achieve cost estimation. Furthermore, the proposed system ensures consistency between BIM and virtual environment information, thereby promoting the application of BIM in the stages of a building life cycle subsequent to building design.
