About Plan889
Our belief
At Plan889, we believe construction planning should be as practical as it is precise.
That's why after more than two decades managing and programming a variety of construction projects, Steph Marshall founded Plan889 to give clients something different:
A partner who understands both your business objectives and the realities of the construction landscape.
Our experience
Over the past 20 years, we’ve managed and planned projects ranging from £200k to £250m, across a variety of sectors.
Our experience spans commercial offices and retrofits, hotels, higher education, mixed-use developments, and heritage refurbishments.
That real-world knowledge means every programme we produce is rooted in practicality for your project, not just ideas that look good on paper.
Steph Marshall
Founder and Planning Director
Steph’s 20-plus years in construction began on-site, progressing from site / project management into dedicated planning roles on some of the UK’s most complex schemes.
His strength lies in bridging the gap between technical detail and human communication ensuring that every programme is understood, agreed, and deliverable.
Steph’s philosophy is simple: Robust but agile planning to deliver certainty, whatever the challenge.
