I translate expertise
into products that scale.
From start-ups to established businesses, I transform domain-specific expertise into scalable products aligned with market opportunities to drive growth.

Who I work with
Financial institutions: Investors in society and resilience
Trusts, funders, and lenders backing resilience and social value, who need investment plans and evidence that stand up to scrutiny. I have spent five years developing investment plans for resilience, and I advise investment committees on what is worth backing.
IFC guidance on climate resilience ↓Physical climate risk analysis ↓Sustainability companies: SaaS, consultancies, and founders
Consultancies and SaaS teams whose revenue ceiling is the diary of their most senior people. I systematise the expertise so the whole team can deliver it, then help you sell it as a product.
Productising climate risk at EVORA ↓Growth strategy for a Glasgow bakery ↓Corporates: Disclosure, risk, and operational efficiency
Finance, operations, risk, and sustainability teams inside larger organisations who need climate exposure quantified in terms the board can act on. My clients are usually C-suite financial, risk, and operational controllers.
Physical climate risk analysis ↓IFC guidance on climate resilience ↓How I work
Sustainability expertise tends to end up in one of two places: a senior specialist's head, or a report nobody opens twice. The three modes below prevent both. Each one builds on the last.
Analysis & delivery, in practice
Typical engagements, decisions first.
Physical climate risk assessment for a portfolio or asset base, carrying hazard, exposure, and vulnerability through to financial consequence.
Putting a defensible figure on the risk the board keeps asking about, using the instruments finance already trusts: discounted cash flow, Monte Carlo, and scenario analysis, in a form an investment committee can act on.
For organisations whose exposure is operational, not just reputational. Built from the decisions you'll face backwards, not from hazard scores forwards.
I take a limited amount of this work, deliberately. It keeps the methodology sharp, and it means everything in the other two modes has been tested somewhere real.
Operational improvement, in practice
Good methodology is mostly decisions made in advance.
What counts as material, what gets measured, what triggers a response, who signs it off: the judgement calls surfaced and written down.
Repetitive steps automated, tools built where they earn their keep, and the workflow documented so the tenth assessment is as rigorous as the first and considerably faster.
The Productisation Audit is the fixed-fee entry point: a review of where your expertise currently lives, what is trapped in billable hours, and what to systematise first. You leave with a map and a sequence, not a proposal for more of me.
Needs from you: access to how the work actually gets delivered, a few hours of senior time, and honesty about your margins.
Commercial strategy & growth, in practice
From selling hours to selling outcomes.
Deciding what the methodology becomes: a service tier, a subscription, a platform, and what stays as advisory.
Who buys it, at what price, against what alternative. Positioning that holds up in a procurement conversation, not just a pitch deck.
Threshold, a decision-first physical climate risk platform, and SyDIR, a structured change-impact assessment tool, both started as methodology and became product.
The scars are transferable.

About
Fieldhouse is Phil Fieldhouse: civil engineer by training (BEng Hons), marine scientist by choice (MSc, Distinction), based in Edinburgh. Nine years across Arup, EVORA Global, and ERM turned that bridge between the built and natural environments into a specialism: climate risk and resilience, quantified in financial terms.
At COP25 in Madrid, representing Arup and Global Ocean Trust, I sat in a room of financiers, engineers, and non-profits grappling with how to prove and scale sustainable solutions. It left a lasting impression, and I have sought out that kind of work since: climate risk with the Wellcome Trust, nature-based solutions with Conservation International and the IUCN, peatland restoration with UKCEH.
The same thing has happened at every firm I have worked in: brilliant bespoke work delivered by a few senior people, and nobody turning it into a method. So I kept becoming the one who built it: the methodology at EVORA, the assessment tool at ERM, the guidance with the IFC. Fieldhouse is that pattern, done on purpose.
It is also why I sometimes wake at 3am to drive to a bakery in Glasgow. What began as baking cookies, cakes, and brownies to help a family friend through maternity leave became an advisory engagement on scaling a small enterprise. The methodology travels.
