I don't think Snorty cares one iota about the renovation. He's over-acting a role of excited interior designer. Snorty is insecure, uneducated, unsophisticated, unaccomplished and rudderless in life. Imagine how boring it must be living remotely at the HMN, especially for a horny 20-something closeted, gay shopaholic! Studying floorplans ad infinitum, constantly shopping online, and getting over-excited about a piece of porcelain or drapery fabric keeps Snorty busy, makes him feel useful and gives him an inflated sense of purpose.
If Snorty really cared about renovation and was interested in history, design & fine arts then he'd go back to school and study to become a professional. Christie's and others have internship programs and education classes (in class & online). He'd work in an art gallery, antiques shop or auction house - God knows he must be connected to enough of them now! But Snorty is bone, idle lazy and after 3 years he's become overly comfortable being a performing monkey for the pink camera and kept gigolo living off of grifted money.
