The exterior set for the fictional Albert Square is located in the permanent backlot of the BBC Elstree Centre, Borehamwood, Hertfordshire, at , and is outdoors and open to the weather. It was initially built in 1984 with a specification that it should last for at least 15 years at a cost of £750,000. The "EastEnders" lot was designed by Keith Harris, who was a senior designer within the production team together with supervising art directors Peter Findley and Gina Parr. The main buildings on the square consisted originally of hollow shells, constructed from marine plywood facades mounted onto steel frames. The lower walls, pavements, etc., were constructed of real brick and tarmac. The set had to be made to look as if it had been standing for years. This was done by a number of means, including chipping the pavements, using chemicals to crack the top layer of the paint work, using varnish to create damp patches underneath the railway bridge, and making garden walls in such a way they appeared to sag. The final touches were added in summer 1984, these included a telephone box, telegraph pole that was provided by British Telecom, lampposts that were provided by Hertsmere Borough Council and a number of vehicles parked on the square. On each set all the appliances are fully functional such as gas cookers, the laundry washing machines and The Queen Victoria beer pumps.
