Pecosmud,
To help you with your planning take a look at them "bug houses" in link below (If link does not work Google "florida screen enclosures".

Saw quite a few big ones that enclose the entire yard in Florida...very popular there. For Chapleau, you can have one imported, but people in Canada would make one for you if you have the wealth to share. But for Canada, you may want to have glass enclosure along with the sreens (with a pool inside) so that the "summer season" can be extended.
Ahhh, might as well do it in style. It's only money.
