Could you please post photos?

My retreat has got water views so TV goes on the wall adjacent to the views.

ie lounge parallel to wall so 90 degrees to views

Can you post the plans? We'll then know where wall space and openings are.

The plans should show furniture layout already? If not some more consideration may be needed before construction gets too far advanced.

You could have the TV hidden in the ceiling or in joinery so it can be dropped down or raised to watch.

Many people get fixated only on the view, the view, the view but everything must be considered when designing, including the times when you just want to watch TV.

I have solved this problem by creating more than one seating area in the space which Depends on the size of your living area.

I set up a couch - with a good looking back facing the window with the view. I included two adjacent chairs and a small coffee table.

The other set of couches and a feature chair are also facing the view but more focused on viewing tv. It is important that you choose furniture on legs otherwise the solidity of the furniture can break up the room too much. Looking at your plan could you hang a tv on a wall on the side of your stairs. One thing I have found with an awesome view - TV becomes less important - 40 inch is big enough - TV size has got a bit out of control!

Some other comments -

think about placing your wardrobes next to each other to create a sound barrier between the bedrooms. If you do this make sure you put sound proofing between the bathrooms.

I note your plumbing location is fragmented which adds to your expense.

Will your garage obstruct your view?

Think about having a sliding door access from the bedroom to the back deck

hope this helps

Thanks Louise. Some really great suggestions and they give us a few things to think about. I think we have just about settled on the eastern wall for the TV with maybe a large L shaped lounge suite with its back to the stairwell to give us both TV and view aspects. As for the block, the slope rises upwards a whopping 33 degrees (I think 1:3 is the measure the builders use?) so the initial design envisages a split level house sitting on top of the garage - the lounge room basically sits on top of the garage. The reason we have designed the internal staircase from the garage entry up into the house the way it we have is to try and accommodate the steep slope, similarly with the steps up from the lower to the upper floor. The design gives us a house or around 14 or 15 metres width which should allow a couple of metres to each boundary.
