The future of our cities is what we make it.

What We do

We advocate a holistic ‘purpose case’ approach to all aspects of city-making and masterplanning, integrating economic, social, environmental and cultural values to generate innovative, inclusive and interdisciplinary solutions for the world’s most pressing urban challenges.



We help shape bold visions to reimagine places and redefine the way built environment projects at various scales are structured and appraised, translating them into real-world outcomes that are measurable.
Integrating system-thinking into the process, aided by the latest digital tools available, we join the dots between people and places, embracing complexity and driving cross-cultural collaboration to deliver resilient, inclusive urban spaces.



Who we work with

We work with governments, municipalities, international agencies and across the public and private sectors, sparking conversation and stimulating collaboration between those who are waking up to the diverse challenges our urban environments currently face and who recognise the value in thinking and working collectively.

About Urban Purpose

Urban Purpose was formed to help the global built environment community deliver much-needed transformational change.
Having delivered city-making tools and techniques across a variety of international contexts, we saw an urgent need for cross-cultural collaboration to help address the critical urban challenges of our time.
That’s why we bring people, projects and ideas together – valuing diversity of thought and drawing on global best practice to create solutions that deliver real ambition and impact.
Established by architect, masterplanner and urban solutions expert Carlo Castelli, we’re based in London, have a global reach, and work wherever our specialist city-making expertise is required.
