See Who We Are

With over 30 years of practical experience in the building industry, our proprietor, Adrian Gibbs, founded this company to deliver a higher standard of construction services built on honesty, expertise, and accountability. After decades of working across a wide range of residential and commercial projects, he saw how easily builds could go off track – from avoidable on-site errors to poor planning and a lack of clear oversight. It became clear that clients needed a construction partner who could provide reliability, transparency, and consistent control.

I recent years, CM3 has expanded its support to three core groups who depend on accurate cost planning and structured project management: architects, developers, and self-builders. We collaborate with architects to ensure designs are commercially aligned from the outset, assisting them in meeting client expectations without unexpected costs. Developers rely on our rigorous planning and management to keep projects efficient, profitable, and firmly on programme. For self – builders, we offer the guidance and clarity needed to manage a once – in – a – lifetime project with confidence.

Across every type of build and every client we support, our focus remains the same: clear communication, dependable oversight, and a commitment to delivering projects that stay on budget, stay on schedule, and achieve the quality they were designed for.

Expert Cost Planning & Project Management

Specialists in Cost Planning & Project Management for Every Stage of Your Build 

Cost Planning 

Effective cost control begins long before construction starts. At CM3 Consultancy, we provide detailed cost planning and budget management from the earliest stages of your project. By assessing design proposals, material choices, and current market conditions, we help clients maintain financial certainty and make informed decisions. Our proactive approach makes sure your project remains on budget and financially viable throughout its lifecycle. 

Design Development

Our design development service bridges the gap between creative vision and practical delivery. Working closely with architects, engineers, and contractors, we refine design concepts to ensure they are cost-effective, buildable, and compliant. By integrating cost and programme advice early in the process, we help achieve the ideal balance between design quality, functionality and value. 

Construction Management 

We take a hands-on approach to construction management, overseeing every stage of the build to ensure quality, safety and efficiency. From coordinating trades and suppliers to managing on-site progress, we provide clear communication and professional leadership. Our goal is to deliver projects that meet design intent, exceed expectations, and are completed on time and within budget. 

Project Planning & Programming 

Thorough planning is key to a successful project. We produce detailed project programmes and construction schedules, mapping out each stage from procurement through to completion. This structured approach enables better coordination, effective risk management, and accurate progress tracking. With clear timelines and achievable milestones, our clients benefit from predictable delivery and minimal disruption.
