Own the Build Leadership Series #3: Mark Walker, Managing Director at Seddon Housing Partnerships (£250m+ Group)

In the third episode of the Own the Build Leadership Series, Paul is joined by Mark Walker, Managing Director of Seddon Housing Partnerships, an £85m social housing contractor operating across the North West and Midlands, part of the wider Seddon Group.Mark’s journey is a powerful example of progression through ownership, resilience and long-term thinking. Starting in construction at 16 as a trainee QS, he worked his way through Assistant QS, QS, Senior QS, Managing QS and Commercial Director — before recently stepping into the Managing Director role.This conversation explores what that journey really looked like.Mark reflects on:putting his hand up for responsibility before he felt fully ready;how difficult projects build the resilience and judgment required for leadership;managing people older and more experienced than you;why bad jobs often create the best commercial leaders;the shift from project-focused thinking to full commercial oversight across estimating, surveying and supply chain;building collaborative two-stage tendering cultures that remove silos;why fairness with subcontractors is not weakness — it’s long-term strategy;the importance of transparency in reporting and contingency management; andwhy ownership and honesty are non-negotiable traits in high-performing commercial teams.Mark also shares the mindset behind his move from Commercial Director to Managing Director — taking control of his own progression, succession planning his role beneath him, and making promotion a logical decision rather than a leap of faith.The episode closes on a clear definition of great commercial leadership in 2026: Create clarity. Build trust. Develop people. And take ownership.This is essential listening for QSs aspiring to senior leadership — and for existing directors who want to sense-check what strong, modern commercial leadership really looks like.---------------------------------📥 Plus: Grab Paul’s free new eBook Mastering Construction Procurement — link below:Mastering Construction Procurement Strategies for Supply Chain Integration, Tendering, and Commercial SuccessSend us Fan MailWant to connect with Paul?Paul is on Linkedin here and would love to talk.
