Unbelievably, a neighbour (who is actually on the EC) has just yesterday affixed a new split system A/C unit on the (common property) balcony of his unit. No permission sought from EC and no prior notification of intention, not even a notice that noisy work was to be undertaken. This unauthorised addition to common property also involved the drilling of hole in the external wall approx 100 mm in diameter. From the postings here it would seem that this owner has opened himself and the rest of us to a host of potential legal and financial problems down the line. Am I correct in assuming that by acting in this way he has ceded responsibility for his new toy to the OC and that the EC can simply arrange its removal so that the common property can be restored to its original condition?
