Diamond Design —
Pioneering Design for Over 20 Years
Diamond Design (Formerly Daedalus Design Services) has been providing engineering, design and metrology services from our offices in Diamond Park in Ecclesfield, North Sheffield. With over 20 years of experience working in manufacturing, we have the expertise to assist in a wide range of projects working within the group of companies and local subcontractors.
In 2025, we rebranded again with our sister companies CTL Seal, TFL Responsive Engineering and Diamond Rail Services to become the ‘Diamond Group’; bringing our complimentary turnkey services together under one roof, streamlining communication for group projects and further increasing the pool of talent, knowledge and expertise available to all.
