About us


The town planning system can be complex and, without experts on hand, can delay the delivery of schemes across the country. What’s more, it’s hard to understand and it keeps changing.

We understand the steps needed to take a site through the planning process from advising on the planning prospects of a potential land acquisition through to works starting on site.

There’s nothing simple about securing planning permissions. Our clients know that our value is in our clear and pragmatic professional advice and input from the outset of a project and through every stage.

We see things differently

We understand the planning system and appreciate its importance for building brilliant places. We know how to work with it, and with local planning authorities, in order to deliver the right results for our clients and for places.

We’re a team of proactive and pragmatic planners who cut through the complexities of the planning system and provide straightforward advice.

Established by Bill Davidson in 2013, P4 has been steadily growing ever since. But we’ve held tight to our original values of close relationships, collaboration, inclusivity and flexibility.

With decades of combined experience under our belt, we’re experts at finding the right solutions: unlocking tricky sites for new uses, adding value to underused land and, through our collaboration with professionals across the industry, helping to build great places.

We focus on what we’re good at

As an independent planning consultancy we don’t spread ourselves thinly trying to master all the built environment specialisms. We focus on what we do best: providing pragmatic planning advice, delivering bespoke planning strategies that work commercially and helping our clients to navigate the planning system.

We understand the planning system with all its technicalities and quirks. We’re proud of our people and our work, and we think outside the box to offer clear, refreshing, proactive advice.
