This project is a great example of how a few simple customizations to any structure can add value, and that value is amplified when we avoid using the bulldozer as an 'easy' out to our housing needs.  The most sustainable solutions for new buildings are far and away those that involve repurposing and upcycling our existing stock of housing, and even our stock-plan builder home neighborhoods could become more interesting places if housing was allowed to evolve and grow in as unique a way as its inhabitants.
