We originally popped up in 2008 as Three Percent Design, assisting a London focused residential developer with specifications and finishing packages for a multi-unit build in EC1.

It went quite well.

Here To Help

With a growing client base of developers, healthcare providers, public organisations and private investors, Three Percent Ltd was formed in early 2013 to very little fanfare and we’ve generally managed to keep ourselves to ourselves ever since.

We've 20+ years of experience working on healthcare, residential and hospitality schemes with a significant interior design, architectural, project management, promotional and developmental background.

Fundamentally, we prefer to work with our clients rather than for them which is based upon a philosophy that most people have an inkling about what they’d like to achieve, but aren’t quite sure how to get there. We’re your conduit.

From small scale refurbishment, decorative and fit-out projects through to multi-million pound development schemes and master planning initiatives, we can provide a full range of services including long term contractual appointments, informal consultancy services/discussions, and everything in between.

We do other stuff as well. Helping businesses with their visual, presentation and branding initiatives. Signage and merchandising. 3D design and development including sketch proposals and fully rendered, verifiable imagery.

If we can help, the chances are we will.
