Electrical System

We've almost finalised the electrical system for our home - the usual upgrading of single power points to double, extra light points, security sensor light unit, bathroom heat lights, etc. We've decided to have ducted air cond throughout the house and ducted vacuum system. We figured having ducted air cond is more cost effective than having separate units of split air system installed in each room. We're also getting wiring done for surround sound system - Kiwi G truly deserves it, to be able to enjoy watching his Sci-Fi DVDs with more oomph (it's a guy thing). Now, these are all pretty standard options that people go for, in a new home. We're not doing anything out of the ordinary. But of course, unfortunately it costs a bomb - you wouldn't want to know.
