For outside the gate—Creating a tall/square cortex column w/ a mail-slot/pull-open-box, succulent plant boxes, and our address numbers backlit on it, cd be super cool!! Cortex nestled in a concrete base would be quite baseball-bat/teenager proof, imho.
Guest House Inspiration: Colonial cottage by the sea ~ dream come true! Love the fencing and the stone walkway too. No fireplace required ~ unless it was electric with the faux brick on top for decoration. Seems a bit wasteful though.
