Starting a new


After getting to grips with the business world, we're proud to announce the start of one over three, a new product design consultancy in Cheltenham.

2020 is the year our new business gets going. Never a straightforward process, have a read about our experiences and  some useful advice we've put together for any aspiring start-up.


Solutions & Compromises.

As a consultancy driven around the principles of the circular economy, consumption and consumerism are at the forefront of our thinking.

Considering the role of the designer as part of a system of consumption raises many conflicts. We've written a short article discussing our thoughts on the issue.
