HGTV’s web series “Tiny House Arrest” proves there’s no concept too small for a successful new angle. By locking up network stars in a tiny house for 24 hours, the series demonstrates in ﬁve, three-minute segments that you can ﬁt a lot of drama—and even some micro-sized teaching moments—in a very small box. The series got off to a solid start by featuring HGTV’s likeable Property Brothers Jonathan and Drew Scott, whose six-foot four frames and good-natured ribbing helped goose up the laughs during their 200-sq. ft. conﬁnement. Attentive viewers might learn something from the lockup as well, with popup facts about small-house living and personal tidbits about the celebrity inmates.
