Our contract with builder was signed November 2013, slab down April quickly followed by brickwork to plate height May 2014. No further work until late September 2014 roof cover completed, within a few days windows and dummy front doors installed (internal 1st fix electrics, plumbing or plastering not completed ) resulting in company claiming roof cover and "lock up" within 48 hrs of each other. Progress payment for roof cover completed, disputed "lock up" claim as per building act guidelines and advised by building commission and not paid. This seems to be common practice for this building group, aware of blog which many more people are in the same position as ourselves. Since late September 2014 no work has been completed on our home, numerous communications with the builder and assurances resulted in no progress. Notice of proposed complaint emailed to builder 8th February 2015, this was acknowledged and replied via email "complaint had been Recieved and will be dealt with in the required time frame". No correspondence received from builder, therefore on 25/2/15 we have submitted a building complaint form to the building commission. We seek advice as to how we stand regarding termination of contract, and law firm who can assist with our situation .
