The Coffee Works Project has several locations across the city. The one I have visited is located right near the Battersea Power Station and is a super cool space.
Chairs and Coffee is a place I discovered back in the Autumn when I was trying to find a place to grab coffee with a friend who lives in Fulham.
Kahaila describes themselves as "a place where community can happen."
Timberyard is located in Seven Dials and is the epitome of a freelancer's dream. They advertise as a workspace powered by purchases.
