Suite 163, 155 Minories, London, EC3N 1AD, London, London, EC3N

We are an independent consultancy on a mission to reconstruct your expectations. Led by MRICS-qualified directors, we combine traditional values with innovative technology to deliver high-stakes commercial fit-outs, industrial builds, and public sector regeneration projects.

Reconstructing Your Expectations, One Project at a Time

We are C6 Projects—an independent team of project managers, cost consultants, and building surveyors. We don't just manage buildings; we manage your ambitions. Whether you are a landlord looking for a Cat A fit-out or a local authority managing large-scale regeneration, we provide the intelligent, cost-effective oversight you need to turn a vision into a reality.

A Visionary Partnership Built on Experience

Our story began with a simple goal: to create a top-tier consultancy that delivers consistent results without the corporate stiffness. Founded by Ian Liddle and Sean Coyne, our firm is rooted in traditional values—professionalism, integrity, and fairness—while leveraging the latest technology to solve modern construction challenges. We approach every project with the same level of commitment, regardless of the scope or budget.

Where Our Expertise Shines

We don't believe in a one-size-fits-all approach. Our team specialises in four key areas where we can add the most value:

  • Commercial Office Interiors: From Shell and Core to bespoke Cat B fit-outs, we help landlords and tenants navigate the complexities of modern workspaces.
  • Industrial & Warehousing: We collaborate with everyone from small operators to international corporations on complex design, build, and refurbishment projects.
  • Public Sector & Housing: We are proud partners to Local Authorities like Enfield Council, delivering Decent Homes Regeneration Works to improve public housing stock.
  • Education: We work alongside schools and academies to deliver complex refurbishment projects within highly demanding timescales.

Led by Chartered Professionals

Our leadership team brings decades of high-level experience and RICS accreditation to your project, ensuring you are always in safe hands:

  • Ian Liddle MRICS MBA (Director / Co-Founder)
  • Sean Coyne MRICS (Director / Co-Founder)
  • Claire O’Sullivan MRICS (Director / Professional Services)
  • Marshal Sequerio (Associate Director / Cost Consultancy)

"We believe that a company’s success should not only be measured by its turnover, but by the positive change it brings about in the world."
