Northern Line (city branch) to Angel. Through the exit barriers continue forward on Upper Street and cross at the second set of pedestrian traffic lights. The Business Design Centre is a few paces further up set back on Upper Street on your left.
There is an NCP car park beneath The Business Design Centre (height 1.9m) and another on Parkfield Street (see roadmap) but there is no facility for booking in advance.
Kings Cross, St Pancras and Euston stations are all within a short taxi ride.
The area is also well served by bus routes.
