I would be careful on any purchase of these. It looks like the uphill/inward houses are being sold before the downhill/canyon facing houses get built. Looking at the architecture style, it is likely the houses that would be built across the street would have cut into the views of these houses.
Outside is a bit bizzare, the grey one looks more interesting architecturally. The view from the inside is nice though. They look like they have an almost ‘vertical’ floorplan, where each ‘floor’ is a different part of your house. Imagine your present house sectioned so that you have to go up or downstairs for the next room – not just across the hall. Worth over $3Mil, I think not.
NOTE: Looks like the south facing windows are not double-paned either. With all that glass – going to get toasty.
