The entire film was shot in an abandoned flat above an off-licence where at the time director Shaun Robert Smith was manager. The team didn't need to carry out any set dressing apart from re-laying some floorboards.
The two children are producer Simon Rippin's children, Shane and Niamph. Shane Rippin went on to feature in Shaun Robert Smith's The Soldier (2007) - along with his dad.
At the time Shaun was shooting 'This Place', he was the manager of a wine shop in Nottingham (UK). The location for 'This Place' is a flat just above that shop and was untouched for years. The production team decided that no set dressing was necessary apart from re-laying a few floorboards. During filming Shaun had an unexpected visit from his area manager, (who knew nothing of the filming) the crew had to hide in the flat for 3 hours without making a sound.
The naked women scene was created when director Shaun Robert Smith joked with Rachel Stringfellow about a scene where a naked women was required, Rachel agreed, so he wrote in a naked women scene.
