Arki Engine.
The research behind the twins.

Arki Engine is our real-time design platform on Unreal Engine. Grasshopper logic drives the geometry, so a pavilion, a tower or a whole district regenerates as the parameters move, with the schedule attached. Everything we learn here goes into the twins.

Watch the tools think.

Four configurators, each recorded live. Sliders move, geometry regenerates, and the numbers on the panel recompute with it.

755 components · 2,257 m² · timber, stock or polycarbonate on one slider

Office T46 · 20 floors · 864 glazed panels · Westminster 3D Tiles

19,551 m² plot · FAR 1 to 6 · parking, set-backs, green ratio

30 levels · 330 planted balconies · 14,584 m² recomputed as you drag

Living model

Our own town, as a living model.

Stockport town centre from 899 real building footprints. Toggle the layers a twin carries: heights, landmarks, the live feeds a council already publishes, and the studio itself.

How the tools are built

From Grasshopper to game engine.

Every configurator starts life as a Grasshopper definition. The RH_IN parameters on these canvases, component count, floor height, form curvature, material, become the live sliders in Unreal Engine, so the logic architects already trust drives the real-time model.

The stack

What the lab runs on.

Parametric logic in Rhino and Grasshopper, BIM in Revit, GIS in QGIS, real-time in Unreal Engine 5 with Cesium and PLATEAU tiling, and a data layer of IFC, TopologicPy, graph databases and FastAPI bridges holding it together.
