Urban digital twins · planning · development · design

Plan the city in a model that answers back.

Living digital twins for planning authorities, masterplanners, urban designers and development partners. GIS, BIM and live city feeds in one navigable model, from the first site study to the day the place opens.

Six layers

Six layers of a living twin.

Every twin we build stacks the same six layers on the same block. A site study might stop at three. A city twin runs all six, live. Hover a card to lift it.

Capabilities

What the twin can do.

Sixteen tools that ship inside the explorer, each recorded in our Stockport East twin. Hover a tile to play it. Every tool runs on the same georeferenced base, so a measurement, a shadow and a bus route all agree.

Three uses

Plan. Test. Decide. One model.

[ 01 / 03 ] PLAN

Masterplans and site capacity, on the real site.

Parcels, blocks and public space generated straight onto the georeferenced site, with GFA, coverage, green ratio and unit mix recomputing as the parameters move. Capacity studies in an afternoon, not a fortnight.

19,551 m² plot · FAR 1 to 6 in seconds · Cesium 3D Tiles
[ 02 / 03 ] TEST

Scenarios compared, with the numbers attached.

Density, height, phasing, daylight, views and transit access tested option against option in the same model. Take the comparison, not the artwork, into the committee room.

330 balconies · 14,584 m² · recomputed as you drag
Try the density slider
[ 03 / 03 ] DECIDE

Consultation, committee evidence, one dashboard.

Residents explore the proposal from their own street and pin comments to the place they mean. Officers get the record, the themes and the export. Once the place opens, the same twin becomes the dashboard that runs it.

Lab

Arki Engine

The research behind the twins. Arki Engine is our Unreal Engine design platform: Grasshopper logic driving real-time geometry, so a pavilion, a tower or a whole district regenerates as the parameters move, with the schedule attached.

Every configurator here started as a Grasshopper definition. The same logic architects already trust runs the live model.

Stockport East Masterplan

What it does. A working twin of the Stockport East regeneration area. GIS layers, key views, dynamic sun and weather, first-person and drone walkthroughs, measuring and section tools, solar and viewshed analysis, POI and transport data, all on one georeferenced base.

What it returns. A model that officers, designers and residents can move through and question. Every capability on this site was recorded inside it. Hover to play the flythrough.

Park and Urban Space Configurator

What it does. Plot area, unit mix, green-space ratio and block typology on live sliders. The park and the blocks around it regenerate directly in the twin, on the real site.

What it returns. Residential units, commercial tenants and green-space ratio recomputed as you drag: 1,200 m² plot, 25 homes, 10 commercial tenants and 35% green space in the configuration shown.

Who we work with

Built for the people who shape places.

01

Planning authorities

A shared model of the plan, the constraints and the live town, so policy, pre-app and committee all look at the same evidence.

02

Masterplanners and urban designers

Capacity, density and phasing tested on the real site in hours, with the numbers attached to every option you show.

03

Development partners

A twin that carries a scheme from feasibility through consultation to consent, and stays current as the plan moves.

04

Transport and infrastructure

Corridors, stations, ports and terminals modelled with their networks and feeds, rehearsed years before opening.

05

Universities and civic programmes

Game-engine tools that teach a place: school programmes, exhibitions and training built on real city data.

How we work

From site boundary to running twin in four moves.

Every twin, from a single site study to a city programme, runs through the same four moves.

Start a twin

Send us a site boundary. We'll send back a scope.

A GeoJSON, a DXF or a red-line PDF is enough to start. We come back with a tier, a timeline and the layers your decision needs.
