The first and second respondents were injured when a cantilevered steel balcony collapsed at the home of the first appellant, Mr Pienaar, in Green Point, Cape Town, on 25 April 2004. The balcony had been designed, manufactured and installed by Mr Lamberts and his close corporation (Ven Projects CC) as a sub‑contractor engaged by Mr Classen, the main building contractor, whose role in relation to the balcony was limited to laying timber flooring once installation was complete. No building plans were submitted to or approved by the local authority as required by the National Building Regulations and Building Standards Act 103 of 1977. The collapse occurred when the screws fixing the balcony to the wall pulled out due to inadequate fastening. The injured guests sued the property owner, the main contractor and the sub‑contractor for damages based on negligence.
