But it's curious that most of the newly-built SSPX chapels follow that same format, given the fact that the Novus Ordo Luther Table has given that layout of the sanctuary a bad name.
My take is that the new-sspx leadership is mostly from Europe and these new chapels give them the opportunity to a) mix-n-match european architecture styles as part of a pet-project of creativity, which is why a "budget" typically isn't followed, b) inflate their european egos, which typically looks down on all things american, c) control the people by introducing non-american but european liturgical "norms" (i.e. norms from the 1930s-50s, when europe was far, far more liberalized than america) and prepare them for the indult.
I've seen sspx chapels do the stations of the cross starting on the right hand (epistle) side and finishing on the left. This must be european because i've always seen it start on the left/gospel side and finish on the right. I don't think there's a liturgical rule, but switching things "just because" is petty and wrong, imo. The liturgical norms of a country are important; not everything should be european style.
