We bought a 1960 brick rambler (solid brick and brick-over-block) house. My wife hates the brick, we plan to substantially increase the size of some of the windows, we are planning an addition (up), we would both like a higher R-value (the inside is too small to insultate inside), and we both love the look of natural wood siding. A designer has suggested we add rigid foam to the outside under cedar siding.
I would appreciate thoughts, recommendations, and avoidable pitfalls in planning out this project. Is it do-able? What kind of rigid insulation? Thickness? Furring strips? Fasterners? Vapor barriers or wraps?
I am a novice. The house is in a humid wooded area in Maryland where many homes struggle against mold. Thanks to the economy, I need to be economical. We would like for the end result to look like a wood cabin, and seamlessly tie the newly sided first floor brick with the new second story. The inside walls are furred with 1x and, yes, 3/4-inch papered fiberglass, and plastered (over backerboard).

EIFS was originally designed for use over masonry walls - consider a straight EIFS application with some decorative relief elements.
Cedar over? What would it be attached to?

I was assuming 1x2 furring strips, with rigid foam in between, but what fasteners would hold best in brick, and also hold the siding on well enough? Would 2x4 be over-kill? Seems it might hold the siding better, but again, how well could I anchor it to the brick?
PL400 and cut nails to hold it till the glue sets!
1x3 furrings strips with foam boards inbetween. Attach furring strips with Tap-cons ( bugle headed, phillips drive type) into the mortar joints only. Then nail off the cedar siding to the 1x3 strips. Also, see if you can get treated 1x3s for the furring strips." Although I have the right to remain stupid, I try not to abuse that right"
You ar practically rebuilding the entire house, so I hope you didn't over pay for it. Be sure to get engineering on the exting structure and soils/footing to support an upper story
Over the brick you can add 2" EPS or XPS foam. Try to get it with borates to keep ants and termites out. Adhere the foam to the brick with a foam gun. I've been using the DOW glue foam formula
Strapping over that should probably be PT because of termites in your area, and it can be installed using GRK caliburn screws. Then your siding.
