It's just the same as a high wall with the external heat exchanger but the interior unit is ceiling mounted and where a high wall can only blow heat or cool air one way (i.e. outwards) but with the ability to change the direction up/down this unit blows in 4 directions and also with the same ability to move the air in a small arc.
We didn't really have many positions where we could have placed a high wall that would have been efficient so decided with the heating/air con engineers advice that it would be better to go for this solution as it meant we could place it in the middle or wherever was best. We have approx 80 SQM of open space kitchen/family room/lounge so having a high wall in one corner wasn't gonna be a good idea.
The cassette is very good even if it's a little more expensive.
To work out the size in watts that you need its the SQM of the area x 100 for a new build or 150 for an older property that isn't to the current insulation standards of a new build.
So for us 80 SQM x 100 = 8000 watts or 8 Kw heating.
This meant we had to go for the largest output cassette available from the company we used and it was $4086 + GST fully fitted with a 6 year guarantee and we also got one of those Pebble control units that connect to the wifi so you can control the heat pump from anywhere via an app on the phone. That was another $234 + GST so all up $4968.

Ceiling will stay the same colour as the vent doesn't blow the air along it. The unit sits proud of the ceiling by maybe 20mm or so, so it is unable to blow air along the ceiling.
As for operation it is completely silent. The only noise is a feint beep when you switch the on/off button.

We moved into the Lakes in August and I think we're in a good spot but as pointed out some of those houses are being crammed in close together with no views and a lot of noise from Traffic. It's difficult to know how new building sites will pan out because there's a lot of hype beforehand. We lived in Matua 5 years ago but thought a new build was a good idea. Personally I would advise anyone to buy a near new established house with the garden sorted. That is my one regret as we're having major issues with the so called landscaping. drainage is bad.

I don't think there is lower standard than UK "lack of standard"
