OK, there are plans for bathroom mirrors, but how about mirrors to reflect the view ?
For example 1 or more mirrors on the south side of the living area or bedrooms that have a northward view over the sea and beach, so that when you look away from the sea, you get these reflected views of the sea.
In the living area, this could be a mirror on the corner post opposite the stairs +/or on the sliding door to the boot room.
With a half height wall between the bed and bathroom area for the 2 sea side bedrooms, the idea is for mirror(s) that are in this open space:
The above photo from the SketchUp model shows how you can see from the bed, back into the bathroom areas.
The current idea is mirrors that are on supports from above and below:
The sinks and storage will probably be different from the above mockup.
From in the bedroom, these can be mirrors on the other side, so that in the bedroom area, they are mirrors of the view out to the sky and sea:
