Haverleij is a new residential area less than 15 minutes from the center of the Burgundian city of Den Bosch in the Netherlands. BPD is developing 8 modern castles here. We have built a home configurator for the Oeverhuijze castle, which was inspired by none other than Windsor Castle. Buyers can easily modify their selected house: add extensions and porches and changing the room layout. Each option is presented via front and rear views and on floor plans. There is also a ‘shopping cart’ showing all options neatly priced, so that buyers understand the impact of their choices. Once satisfied, buyers can save their chosen configuration and download a personalized brochure.
