Lots of interesting emotion on this subject but little fact so be careful that you do not end up with costly legal enforcement aginst you or the property.
one thing that I would definately check is your lease as this is usually very restrictive about noise and times for workmen including DIY. There is lots of case law on this so you should do your own research as I bet the Lawyer downstairs has and by informing you of his objection is well into the first steps of the process.
have you tried talking to him to see when it would be convenient, perhaps it is worth you taking a bit of holiday to finish the job if you knew when he was not around. keep a record of what you offer him just in case it goes further so that you can show you were prepared to be reasonable.
God luck and hope it works out for you.
