ACCELERATING PROJECTS THROUGH BUILDABLE DESIGN
By focusing on what works, from early engagement through to complex detailing, we help you move faster, build better, and create lasting places. Our designs are strategies for delivery, sustainability, and real-world impact.
WE DESIGN BUILDINGS WITH DEEP UNDERSTANDING, CROSS-SECTOR INSIGHT AND CREATIVITY
ABOUT US

We operate as one fully integrated team, redefining how projects are delivered and procured. From initial concept through to construction on site, we spot opportunities early, streamline delivery, navigate regulatory requirements, and provide accurate, buildable solutions that work in the real world.

 

We achieve all of this through bringing together teams of:

 

  • Civil Engineers
  • Structural Engineers
  • Construction Engineers
  • Construction Modellers
  • Detailers and Technicians

Driven by bold thinking and a commitment to innovation, we’re transforming construction workflows to create lasting value, for the delivery team, the end-user, and society. By embedding sustainability and forward-thinking practices into everything we do, we go beyond convention to deliver smarter, safer, and more cost-effective outcomes.

THE MINDS MAKING IT HAPPEN

“We are progressive, we challenge the norm, we find the right solutions for our clients and we deliver. As Managing Director, I’m deeply committed to championing this vision and strengthening our reputation as the engineering consultancy that truly delivers on its promises.”

 

MATT GOOLD - MANAGING DIRECTOR

“Our mission is to deliver smarter, more predictable, and sustainable outcomes for our clients. Our focus is on driving positive change through innovation. With over 20 years in the industry, I’ve seen first-hand the impact of combining digital solutions with technical expertise. I’m a firm believer that with the right people by your side, you can achieve great things, and I’m incredibly proud of our teams and what we’ve accomplished.

DANIEL LEECH - CEO

“Taking it one step further, as we do at D4S, incorporating the stage 4 and 5 detailing and fabrication information during the design phase, means you can inform other contractor requirements within the supply chain. It’s an approach that enables us all to overcome issues associated with procurement, timescales and cost, which of-course, have a knock-on effect towards sustainable outcomes.”

JONATHAN LOCK - CHIEF COMMERCIAL OFFICER

“I joined the business as an apprentice CAD technician, more than 25 years ago and progressed through hands-on experience to eventually take on joint ownership and more recently the role of Chief Operations Officer. This journey has shaped how I lead, placing strong emphasis on technical excellence, structured delivery, and collaborative teamwork. At D4S, we challenge convention where it adds real value. The best outcomes come from a coordinated team working with precision, purpose, and shared pride in what we deliver.”

JAMES MCNEE - CHIEF OPERATIONS OFFICE
