About Us
We founded Quintic Advisory to bring clarity, rigour, and independence to development viability. Our founding partners previously worked together over several decades at BNP Paribas Real Estate and identified the need for a more focused practice, combining technical depth with the agility and attentiveness of a boutique firm.
Our work is grounded in a simple principle: we seek to demystify complex issues. We work closely with our clients to provide analysis that is transparent, defensible, and aligned with the realities of delivery. Whether supporting a planning application, shaping a development strategy, or advising on investment decisions, we bring a balanced perspective rooted in experience and pragmatism.
Our Approach
We believe in precision, practicality, and open communication. Our modelling is built to withstand scrutiny, our advice is grounded in policy and market realities, and our outputs are designed to be understood by decision-makers. We prioritise clarity over complexity, ensuring that our analysis leads to actionable insight.
We work collaboratively, adapting our approach to the needs of each project whilst maintaining a consistent commitment to quality and independence.
