Useful maps. Working tools.

Climate evidence for places and buildings, with its limits drawn in. I build spatial intelligence for teams working on cities, climate and location: documented data, reproducible analysis and maps or tools people can use.

For climate-risk questions, contract work, team roles and research collaborations.

Based in London; remote or on site by agreement.

Day rate or fixed fee, agreed for each engagement.

A useful first step, with a clear scope.

You do not need a polished brief. Tell me about the place, problem or idea, who the work is for and what you already have.

  1. Understand the question

    Define the question, users and available evidence.

  2. Agree the work

    Agree outputs, fee, timing and what the data cannot answer.

  3. Build and hand over

    Receive the work, documentation and a practical walkthrough.

How I can help

Spatial data products

Location analysis, data pipelines and software for decisions about sites, audiences and neighbourhoods.

For retail and media teams, planners, climate ventures and consultancies making decisions about sites, audiences or neighbourhoods.

What you receive

  • Data pipelines and APIs, with source documentation
  • Site, catchment, cannibalisation and audience analysis
  • Interactive maps, dashboards and web applications

This is analytical decision support. Specialist engineering, medical, regulatory and investment advice are outside scope. Sensitive-data handling, extensive fieldwork and ongoing operations need separate agreement.

Urban Heat Diagnostic

One place. One heat-adaptation decision. Ten working days.

A priority map, decision brief and evidence register, with the data gaps made clear.

For local-authority climate and planning teams, housing providers, asset owners preparing physical-risk evidence, place partnerships and specialist consultancies.

Screening and prioritisation, not individual risk scoring, causal intervention proof or medical, engineering, regulatory or investment advice, and not materiality, compliance or assurance advice. It does not include a permanent platform, extensive fieldwork or operational monitoring unless separately scoped.

Fixed fee, quoted after a short fit call.

More ways I can help

Applied environmental research

Investigate urban heat, material flows and how people use places, with reproducible methods.

For universities, urban research teams and sustainability organisations looking for a research partner or specialist contribution.

What you receive

  • Research design, data review and reproducible analysis
  • Spatial machine learning (GeoAI), with model evaluation
  • 3D urban-form analysis, maps and a methods report

We agree data access, attribution and publication rights at the outset. Findings are tied to the places, sources and methods studied; predictions are not causal proof. Peer review and grant outcomes remain outside the agreed work.

Technical discovery and prototypes

Hands-on technical direction for early-stage teams: test the difficult assumption, build one useful workflow, know what to do next.

For early-stage climate, spatial-data and AI teams that need hands-on technical direction and product development.

What you receive

  • Technical feasibility review and first-build plan
  • A focused prototype for one user workflow
  • Architecture, documentation and a technical handover

Completed engagement2026, ended OctoberRead the CommunityAI audit and delivery case

A prototype is an agreed test of a product idea, not an automatic production release. Funding, market demand and customer outcomes are not promised. Client information and unpublished technical findings remain confidential.

Mapping and creative commissions

Explore a place through an interactive story, a printed map or a walk.

For cultural organisations, researchers and public-interest teams commissioning work about a place or environmental question.

What you receive

  • Interactive maps and 3D spatial stories
  • Editorial maps, posters and print-ready zines
  • A guided walk with a digital or printed companion

Ongoing practiceOpen the map

We agree image and data rights, accessibility, participant consent, print or installation requirements and any ongoing technical care. A participatory work does not represent a whole community or substitute for formal consultation.
