Modern style two storey two bedroom home concept

I have just completed this very rough concept for a two storey two bedroom home, which I was asked to prepare. There is no fixed schedule for construction, though, as the client is still looking for the right plot of land on which to build.   It is for this reason that I call the design a 'very rough' concept, as a lot could change depending on the chosen plot of land.  Not least the size and shape, but also the orientation of the land would play a big part in the design with regard to positioning of windows for best views and allowances for protection from solar heat.
