Wallpapered was set up in late 2010 and the company is located behind Westminster Abbey in central London. They have many up and coming designers on the site including Jessica Townsend: http://www.wallpapered.com/jessica-townsend and Khristian Howell http://www.wallpapered.com/khristian-a-howell.
I love the fresh patterns and murals that one can choose from, they even have textured walls from brick to cheetah! If you are a traditionalist there are masterpiece paintings that you may install. I posted one that I love and can imagine it on a dining room wall or in-between book shelving.
If you are looking for a way to bring your office space to life consider one of the many cool map murals to choose from.
This company will ship outside of the UK , definitely worth checking out! Wallpapered!
