This paper presents a live and tested solution that enables home buyers to choose and customise their future homes in a web browser. It allows future owners and residents to configure and visualise their home in 3D but also keep it affordable by displaying the construction costs back to users in real-time. The proposed solution is analysed in the context of current housing market, excising web and BIM technologies and compared to currently available solutions. Additionally, we have been tracking visitor behaviour by using web analytics and can draw some conclusions about its performance.
