CAD21 deliver innovative, sustainable and cost effective mechanical and electrical design solutions for all retail applications. Our portfolio includes value-driven supermarket design, mixed use developments and high-end vehicle retail from individual shop units to full retail park developments.

Repeatable cost-driven design 

CAD21 have consistently worked in supermarket design for more than 20 years and know how to deliver cost-driven commercial design on time and on budget. 

We tailor engineering and design requirements to fit the requirements of each specification to ensure we provide a robust and good value solution for our clients. 

Without reservation I am pleased to recommend CAD21 as one of the MEP Consultants I have had the pleasure of working with in my 30 years in the industry. I recall an instance on a recent commercial project in the NE, CAD21 saved the project a large cost to provide PV over the offices and factory. Through CAD21’s sector knowledge, we were able to limit the PV to the commercial area and drastically reduce the associated costs. Simon Preston - National Frameworks Director, Imtech

Flexible commercial solutions

Our team understands the complexities of mixed-use joint developments, including the flexibility required for rented spaces. 

We provide versatile service solutions that can be easily adapted to suit a variety of uses. Most importantly, we consider the commercial factors involved in rental units.

Bespoke brands

Cars are usually a consumer’s second most expensive purchase after their home, so creating an enticing environment and brand specific perception is crucial in vehicle retail. We’ve worked with the likes of Reg Vardy, Vertu Motors and Arnold Clark and understand the specific requirements for designing automotive showrooms and back of house areas.

Our team is experienced in working closely with specialists involved in garage workshop fit-out to ensure we have correctly considered factors such as power supply and lighting levels.
