Design Development - Initial Concept Design

The ideas i have for the design are just few elements i want to capture: Industrial, connection to nature and harmony of art and nature.

I started by designing the facade with a hint of 'industrial' feel, adding elements like metal panels and steel beams.  The the slop roofs that descend into ground level are like roots into the ground which symbolising the connection to the land.  And lastly i play around and explore with the form to see what other options i have.
