Township Spatial Explorer
A 48-acre, 14-tower residential township in Bengaluru. We built a browser-based explorer that takes buyers and sales teams from the masterplan down to a single room — in 3D, in VR and on a map — with nothing to install.

Project figures from the developer's sales collateral.
The challenge
Start from brochures, not BIM.
There were no CAD drawings, BIM models or 3D assets to work from. The source material was sales collateral: vector floor-plan PDFs for seven unit types, a raster masterplan with no scale bar, a mobile brochure and a pricing sheet.
The explorer still had to be accurate enough for a buyer to trust — and honest about anything that had to be assumed.
What buyers can do
Explore the community
The site model on real terrain, with time-of-day sun (and a night sky after dusk), all 14 towers and the masterplan landscape: roads, club, running track, sports ground, water and trees.
Step inside a home at true scale
Each unit is built 1:1 from the printed plan dimensions, furnished, and set at its real floor with the neighbouring wings and satellite ground outside the windows.
Take a guided tour
A narrated tour flies from the gate past the club and the stadium to the chosen wing, then steps inside and walks room by room.
Enter VR from the page
On a Quest headset: walk, snap-turn and teleport, or use hand tracking to drag and rotate the world. No app to install.
Find, shortlist and compare
Filter by tower, bedrooms, finish and facing down to a single flat. Every selection lives in the URL, so any view can be shared.
Check the location
A satellite map with points of interest, distance rings and a measure tool — map distances only, never invented travel times.
Engineering notes
The parts that took the most care, because they decide whether a buyer can trust what they see.
Scale from the drawings themselves
With no scale bar on the masterplan, the site was scaled from features with known sizes — the 90 m sports ground and the 60 m highway frontage — and registered against OpenStreetMap.
Two frames, one site
The masterplan trace and the explorer's georeference disagreed by 60–90 m and about 18°. A similarity transform fitted on the 14 tower centroids brings them together to about 3 m RMS.
Useful before it's pretty
The interface and property data load before the heavy 3D, one WebGL context is live at a time, and on touch screens one finger scrolls the page while two drive the camera.
Every fact has a source
Figures carry a provenance badge — sourced, estimated or illustrative — so a buyer can tell what came from the developer and what was modelled.

Where it stands
A working demo ahead of the project's public launch — open it on a phone, tablet, laptop or Quest headset, or ask us to walk you through it.
Values the collateral doesn't provide — floor-to-floor heights, a surveyed site coordinate, live inventory — stay labelled as assumptions until the developer confirms them.
