Hello John,
The house in the D doesnt work mainly because we a larger scale builder and the house relates to a smaller builder. We build Unit blocks, commercial - shopping centres, Industrial buildings...
your original design plan planted the seed for use of the southern cross... so I am exploring it with you...what about the silhouette of the earth...australia to the top...maybe the southern cross..maybe not
The D could even be the silhoutte..australia could be the hole in the D..maybe
Cheers
