When Erva bought Nature House back in 2006 and moved manufacturing from Griggsville to Chicago, I (and many others) were hopeful they would carry on the Trio/Nature House tradition indefinitely.
Over time there were changes (some stung more for us Trio/Nature House fanatics than others) like ending the budget DuraCraft line with its signature embossed stucco textured surfaces, ending the TG-12/MSS-12 "spaghetti rails", etc.
There were also product improvements, like precut holes in the inner compartment walls for easy expansion to larger compartments, including Dri-nest subfloors with the M-12K house for the first time in its history, and louvered blank doors for better airflow.
However, for whatever reason (obviously for profit maximization by eliminating the machines and materials associated with the production of components specific to Castle/Mini-Castle houses), they've effectively killed the Castle and Mini-Castle lines.
I'm not a business owner, nor do I pretend to know what it takes to run a successful business, but one has to wonder when a company produces something that is no longer profitable for them, but it's still a great product AND has a special history and significance associated with it, at what point should that company consider selling that product and all its manufacturing components to a company that's interested in continuing to produce it, instead of keeping and killing it altogether?
