Changes cost builders time and money… Therefore, when you make a change to your building contract, expect to have your completion date extended and a charge to be made for the delay and the cost of any additional work.
A change order also involves a lot of admin work for a building company, therefore expect to pay an administration fee on each variation that is raised.
Generally, any change made after contract will involve delays either through additional work or as a result of delivery times. Before you sign off on any change order, check how many days have been added as an extension of time as these will push out your completion date.
For instance, changing your shower head style could involve more than simply ordering a different fitting. It could require a different valve that gets installed in the wall before wall board or tile can be installed.
