Started in a Bristol Flat, Now Nationwide

In 2009, Dr. Helen Cartwright left her position at a large engineering consultancy frustrated by how often ecological concerns were treated as afterthoughts. She founded echo-chassis with a simple premise: better ecological advice delivered earlier in the planning process prevents costly delays and produces better outcomes for wildlife.

What began as a sole practice operating from a spare bedroom has grown into a team of twelve specialists working across England, Wales, and Scotland. We've retained our founding principle: ecology should inform design, not just react to it.

Our Core Values

Scientific Integrity

Our recommendations are grounded in peer-reviewed methodology and defensible data. We never overstate or understate ecological constraints.

Practical Solutions

Identifying a problem is only half the job. We specialise in mitigation strategies that work within real-world construction constraints.

Client Partnership

We view ourselves as part of your project team, not an external box-ticker. Expect proactive communication and accessible expertise.

Continuous Learning

Ecological science evolves rapidly. Our team dedicates time each month to professional development and emerging research.
