@hummerd, Yes I believe you about the skylight but we have a truss roof design, which puts the room ceilings some 3m away from the actual roof and so a skylight that actually opens can't be installed in this bedroom or anwhere else in the home unles we had a cathedral ceiling, otherwise it would have been a simple procedure. Disapointed that we can't use this method but it's not to be!! A tube skylight is our only other option but we were wanting one that allows you to open and close an internal vent situated on the ceiling, as well as on the roof, our daughter has one like this but they aren't made anymore. It seems they are now only vented on the roof either permanantly or with a motor that allows you to manipulate the amount the vent is open. Price has now jumped from a standard $200 to at least $600+ and rising but none of these tube skylights have an ajustable vent in the ceiling which we would prefer. We will have to keep looking and thanks for your thoughts. Cheers, Barbara

Also do we include the velux in the ensuite?

The first question would be whether the 'new' position interferes with any of the diagonals on the trusses , or anything else that is already prepared or installed , such as walls or even iron ( which may already have the holes positioned ) . So the short answer is you will need to ask the builder , but it sounds like you may be early enough that it MAY be possible .

Unfortunately it often costs more to have trades teams work to recycle and reuse existing materials. You may find it easier and cheaper to totally replace the roof and then sell the secondhand sheets.
