Our Philosophy and Mission

We believe that current and future generations should have a healthy and beautiful built environment that promotes well-being and facilitates prosperity. Planning, urban design and spatial intelligence are at the heart of achieving this aim by considering the three key factors of location, form and function. Planning is about where developments are located, urban design is about the form these developments take, and spatial intelligence considers how new places function.


Wonderful places are rarely created by accident. They are normally the result of careful design that creates an appealing balance between order and variety. This can be achieved through the application of clearly specified design codes, by detailed master planning, or via a shared cultural understanding of place.

Our Director

PUDSI was established by John Eltham in 2017 with the aim of helping communities demand a better built environment from both developers and government. He is passionate about places, planning and urban design.


He believes that planning should be seen as a proactive creative process and is frustrated by the fact that it is often perceived as a regulatory reactive process. He aims to change this perception.


He has over 28 years experience as a town planner in both the public and private sector, having worked in every sub sector of planning including development management, planning enforcement, local development plans, and urban regeneration.

How We Work

PUDSI operates as a social enterprise with the purpose of creating a healthy and beautiful built environment that promotes well-being and facilitates prosperity. A social enterprise is defined by government as a business with primarily social objectives whose surpluses are principally reinvested for that purpose in the business or in the community, rather than being driven by the need to maximise profit for shareholders and owners. 


PUDSI is the trading name of John Eltham operating his business as a sole trader. John works with a network of other freelance built environment professionals including town planners, architects, civil engineers, landscape architects, and urban designers. He can call upon their expert advice whenever needed.
