I'm considering a detached screen house as part of our landscaping
projects for next year. This is in central MN; our lot is about 2.5
acres and 1/2 of that is wetland so we have lots of mosquitoes. Soil
is clay and the lot slopes very gradually toward the wetland. Location
will be about 25 feet from the back porch and there will be a paver
patio nearby for BBQ, etc.

My first thought is a simply 24x16' building, gable roof with 16"
overhangs, with 24x48" screens above a knee wall on all four sides.
I'd place the door on the 16' end and use 4' for a covered porch. The
structure would be on piers with the floor about 24" above grade,
which would both move it above some of the bugs and keep it out of the
snow for part of the winter. I'd probably use fiber cement for siding
and some sort of panelized (steel or polycarbonate) for the roof.

Anyone have something like this? Seen plans somewhere? Have thoughts
on design I should keep in mind?

thanks,
