The photoabove was taken on Clarendon Road, Borehamwood, just a stones throw away from the studios and, incidentally, just near the main entrance to BBC Elstree, where EastEnders and Holby City are filmed. In fact you can just make out a green area bridge in the gap between the houses towards the right hand side of the photo, this is part of the EatstEnders Albert Square set.
You can also just see that there is a left turning towards the middle of this photo. This road that leads of Clarendon Road is called Malden Road, and is the road which features Stan Butler's house in all of the On the Buses spin-off films. In this, the first spin-off film, the house (2 Malden Road) and the corner of Clarendon Road, can be seen at the end of the opening title sequence when Stan drops mum, Olive and Arthur off home, giving them a free rise on his bus! The house can also be spotted in a a scene where Stan and mum are helping to get a very pregnant Olive, who is on her way to hospital, into Arthur's old motorbike side-car!
The laundrette featured in this film is still situated on Manor Way, Borehamwood, just around the corner from the film studios and not far from the old MGM Studios. I intend to get photos of this location on a future visit to Borehamwood.
Finally, for the first On the Buses film, although I don't currently have a photo of this glamorous location at present, the motorway junction seen in On the Buses, was Junction 4 of the M1. And as you might have guessed, this junction is only a few miles from the studio.
