About us

Company owner James Barr BSc (Hons) established a limited company in 2014 to work directly with clients. With a network of trusted manufacturing partners James Barr Design has reliable links to prototype and manufacture products.
James has been a consultant designer since 1999, working in a wide range of industries as both a consultant and in-house senior designer. Consultancy work requires the ability to research and quickly understand any products unique challenges and opportunities. Running in-house design teams requires great attention to detail for all aspects of a product launch including quality control, graphic design and packaging.
We specialise in CAD product design in Surrey, London, Kent and Sussex but do take on clients across the UK and Europe. Communication is key; regular zoom meetings, calls and emails keep our clients well informed on progress.

Experience and technology
Having worked since 1999 in product design and engineering we have a wealth of experience to draw from both in terms of manufacturing knowledge and aesthetics. We use the very latest 3D CAD systems (SolidWorks Premium), and have in-house 3D printing and 3D scanning technologies.
Having invested in rapid prototyping equipment and industry standard design software our design process is very efficient meaning we can develop concepts in a few days and produce working prototypes in under hours.


Evaluation of physical prototypes using 3D scanning and in-house prototyping allows for fast iterative testing of components.

We use the very latest version of SolidWorks (Premium) to generate our 3D parts, assemblies and 2D control drawings. It can import legacy data from most common 3D file formats for reuse or as a reference.
SolidWorks is the industry standard software for designing and releasing information to prototyping and manufacturing partners.

The use of industry standard 3D CAD offers numerous benefits; it’s the old adage of using the ‘right tool for the job’. In the early stages of product development structural components can be run through FEA simulations (Finite Element Analysis) to highlight possible points of weakness.
Additionally, CFD simulations (Computational Fluid Dynamics) of how liquids fill a void, airflow and aerodynamics can show where efficiencies can be made.
Over the last 20 years we have worked on projects in an extraordinarily diverse range of industries including:
Access control, nuclear inspection, sporting goods, fragrance devices, (medical) disposable diagnostic, laboratory equipment, oil industry, construction equipment, DIY, marine safety, mother and baby, toys, martial arts, military, high-end audio products (amps), loudspeakers for consumer and retail market, AV systems (home automation), FMCG, packaging, transport, education, furniture, medical equipment handling, medical patient entertainment, consumer electronics, lifestyle products, sustainable products, security, process containment, industrial machinery, Healthcare – rehabilitation devices, marketing and promotion, barcode scanning, industrial workdesks, signage, point of sale, digital wayfinding, security, motorsport advertising, dental PPE, flight simulation, household goods, exhibition planning, wound care, luggage, petro-chemical, building & associated trades, cryogenics, industrial 3D-scanning, plush toys, airsoft, mountain bike accessories, home security, promotional gifts, gaming accessories, keyboards, pet care…
