Measure twice and build once.....or be prepared.

You've designed and redesigned, and waited patiently as your planning details were displayed on a lamp post on your street, for any neighbours to register their disputes and finally the building of your new extension has begun. 

But how precisely are your contractors building to  your plans? Disputes with neighbours arguing that your extension is just three inches bigger or on their land slightly can lead to expensive and disastrous consequences.

If neighbours believe, report and win a battle over your extension, no matter how small the misinterpretation of the plans, could lead to you being ordered to knock down and rebuild your extension, at your expense. 

The moral of the storey - build what you have planning permission for and do not think you can add a little here and a little there and no one will notice!
