6 weeks in and still plagued with problems

While happy to finally be moved in, we're finding more and more issues with the house on a daily basis.

Leaking Ceiling
We had someone in on Saturday to remove brickwork from the front of the house and replace some torn DPC as we had water leaking through the ceiling of the home theatre room over the last few weeks;

Leaking Door
We've also discovered the laundry door lets the rain in and has a tendency to flood the floor of the laundry and soak into the laminate floor of the galley;

Leaking Windows
Our A&L double glazed windows whistle in the wind. A&L have been out 4 times to try and fix these - which we have in multiple rooms, but have so far been unable to resolve the problem;

Leaking Front Door
The front door was replaced not long after moving in as the stain on the door wasn't right, but the replacement door was damaged and so for the last 4 weeks we've had to put up with a front door that also whistles in the wind;

This front door has been replaced again today, so hopefully the replacement stops the whistling.

Clattering Eaves
The eaves clatter around in the wind. Makes sleeping a nightmare.

Wind In The Walls
And the one I worry about most is the excess of wind in the internal walls. The following video is taken in the home theatre on an internal wall at least 10ft from an external wall. We have brick, sisalation, external wall insulation, internal wall insulation, stud, noggin and double glazed windows all between the external and this socket on the wall, yet still a high volume of cold powerful wind from the outside is able to blow directly in to the room from the speaker cable plates. It's almost like we have no protection from the wind at all. Is this really what new houses are supposed to be like? How does this in any way conform to 6 star energy rating if the house leaks air like a sieve;

So much for all the problems ending once we moved in :(
