This may be off-topic, but I've had a passing thought over the years of the evolution of opensource to expand to the blueprints, architecture and building-codes of residential homes to simplify the upfront costs and options of new construction for specific needs (starter homes, bachelor pads, tiny homes,etc). In the US for instance, could we take all of the local building-codes and design blueprints that would satisfy all of the legal requirements for quality, sustainable construction, regardless of the state, city or county that you choose to build in? Even going with a smaller scale and offering off the shelf blueprints by state may stimulate more new construction growth and sustainable designs.
