Clapham Woods Farm, Keasden, Clapham, Lancaster, Lancashire, LA2 8ET, Lancaster
We are leading viability and housing consultants who don't just follow the rules—we help write them. Led by Simon Drummond-Hay MRICS, we provide expert evidence for Local Plans, CIL assessments, and S106 negotiations, backed by decades of professional practice and development experience.
We are a specialist firm of planning and development consultants dedicated to providing the robust evidence needed to navigate the complexities of the modern planning system. Whether we are supporting a local authority with a Whole Plan Viability Assessment or helping a developer through a sensitive Section 106 negotiation, our goal is to provide clarity, accuracy, and professional integrity.
Expertise That Shapes National Planning Policy
We aren't just consultants; we are the experts that the industry looks to for guidance. Since 2013, we have delivered viability support and training for the Planning Advisory Service (PAS) and co-authored national technical advice notes on housing need and tenure. When you hire us, you are hiring the team that has helped define the standards for housing and economic development needs assessments across England.
"We are a team of like-minded, positive people who care deeply about what we do, bringing a wealth of experience from both consultancy and direct development backgrounds."
Why Local Authorities and Developers Trust Our Evidence
Our firm is led by Simon Drummond-Hay MRICS, ACIH, a Chartered Surveyor who has been qualified since 1992. Simon’s unique background—spanning land agency for major estates like Savills to serving as a Development Director for affordable housing providers—gives us a 360-degree view of the property industry.
We understand the pressures on both sides of the table. This dual perspective allows us to produce assessments that are not only technically sound but also practically deliverable.
