so we went to see a lawyer who took one look at the letter and confirmed it wasillegal. he phoned the landlord who feigned ignorance of the law and confirmed that he wanted to do renovations and not demolish the place. he then said that he would be willing to allow us to stay until July which is the end of our contract,but once again the lawyer pointer out that under the law we can stay here for the next 2 years with only a 10% increase in rent per year to which the landlord replied he would need to see this in writing. so the letters have been sent and the lawyer seems confident that this should stop he landlord in his tracks. Here's hoping. we wait to see the outcome...
