The previous suggestions are fabulous, so if you have the money, I would go with one of them. If you haven't the money, then I would do what an earlier reader mentioned and have the bed facing north near the bathroom. You can run a power cord along the floor and you can buy white plastic covers that hide the power cord discreetly on the skirting board. Then place a chair and small table beside it near the bay windows to balance the length of the room and perhaps hide the power point. This is not the best solution as it'll make the bed hard to make and have little room for a bedside table. But it is cheaper. Just an alternative. Another way to do this cheaply would be to do what Two Company's Renovations suggested but instead of building a wall using your cupboards as the wall and making your own large, bed head to cover the back of both of the cupboards. Just a thought. Still building the wall or walk in may not be as expensive as you may think. Worth getting a quote.

The builder is going to price it for me no come back with the price difference, we haven't signed contract yet, but they are aware that our budget doesn't have all that much room to move. I am thinking of painting the walls that aren't tiled white, but wonder if I matched the paint to the tile colour this would look better, or just weird? I found a picture which has some grey tiles and white walls, but I think my grey tiles are a little darker than this, and different vanity, layout etc

Jodie, measure 212cm from your floor and mark with a sticky note or piece of tape. Measure from the mark down 70cm - this represents bottom edge of mirror. Will this be adequate for you and other adult/s using it?

Thanks all for your advice. Ive included some renders that I made with view along the corridor with and without the bulkhead. I don't think renderst does it justice until you actual walk through @ frame stage. I agree that ceiling height and comfort and look, depends on climate, orientation, insulation, relative proportions of other parts such as windows/doors. Because of the Melbourne climate, we have planned for double glazing, and good insulation with R2.5 batts wall, R6.0 ceiling. We have 2.4m height of windows and door around the ground floor which is btw 3 to 3.6m so I think proportion wise should be ok. In the family where it was always planned 3.6m from the start, we have a band of clerestory windows too. We have decided not to be too excessive with windows ( ie 3m and even 3.6m floor to ceiling - how grand would have that looked though! ) to minimise heat loss during winter. Energy rating for house is 7 stars so far. Thanks for giving me the pro and cons - I have some more confidence to let it stay at 3.6m throughout now.
