We ended up adding 3 Double GPO's and relocating a few so that they were directly opposite on an internal wall where we wanted to add later as we know an Electrician. In addition to this we added an external power point in the Alfresco and 3 Junction Boxes on the front facade for future lighting (these are $90 each).
We wanted to add a further 2 at the kitchen bench, however were advised that Carlisle will not put power points on the glass splashback which was disappointing.
As our promotion was from May last year, we had the 4 "As Displayed" upgrade packs included in our price. Outside of these we only added very minimal upgrades - mirror sliding doors in the bedrooms, an upgraded "wood look" wall tile in the ensuite (which I am hoping is not too expensive - would be interested in hearing peoples upgrade costs to a 300x600 tile in the upgrade range), and an upgrade to the front door and lock.
We are just waiting for our land to title now so that we can go to Tender, which is due late Feb hopefully.
