Wierda Road West Properties (Pty) Ltd (appellant) owned a property at 41 West Street, Houghton, Johannesburg. The appellant purchased the property at auction in 2009 to house Gobodo Incorporated. The property consisted of an original two-storey dwelling and a three-storey wing added by the previous owner, for which no building plans existed. The appellant instructed architects to draw plans and submitted them to the City Council of Johannesburg, but approval took approximately five years (mid-2015). Without approved plans, no occupancy certificate could be obtained. On 1 August 2010, Gobodo moved in under a 12-year lease. After Gobodo merged with SizweNtsaluba VSP to form SizweNtsalubaGobodo Inc (respondent), a new lease agreement was concluded on 3 August 2012 for 5 years. The respondent occupied the property and paid rent from August 2012 to June 2014, when it vacated without notice. The appellant sued for unpaid rentals and municipal charges of R7,867,548.78 for July 2014 to March 2016. The respondent defended on the basis that the lease was void ab initio due to non-compliance with sections 4(1) and 14(1) of the National Building Regulations and Building Standards Act 103 of 1977, which require approved building plans and occupancy certificates respectively. The respondent also counterclaimed for a declaratory order that the lease was void.
