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 with very little fuss and we’ve generally managed to keep ourselves quite busy ever since.
