Pricewalk turns Bay Area home prices into a place you can explore. Set your budget, compare seven cities, see real asking prices as a 3D landscape, then select a home and fly from the neighborhood down to its actual street. A persistent property card connects the experience to the selected address, asking price, bedrooms and floor area.

The demo includes 234 sampled real listings. City overview values use Zillow ZHVI; individual asking prices come from RentCast. Column height represents price, and color reveals lower, middle and higher price bands within each city.

Built for More Dimensions, Pricewalk also implements a render → record → watch → critique → repair → verify loop using Gemini 4 Argon and Google Managed Agents. A completed run corrected overlapping navigation and reduced measured overlap occurrences from two to zero.

The application, visualizations, photographic tour integration, agent orchestration and tests were built during the hackathon. Data acquisition and geometry preparation preceded the event; third-party imagery and data are attributed separately.
