After emulating the dwellings of Federal-era Salem and Portsmouth for his own house (WB5; 2 Raleigh Street) in 1890, Arthur Little crosses the pond to evoke Regency Bath and Brighton antecedents here at 422 Beacon Street. Though an ironically expensive stand-in for British stucco, pale limestone thus supplants warm red brick, and random fenestration yields to a tightly controlled program in which five tiers of window openings ascend from a rusticated two-story base to a panelized parapet. By their elongated proportions and the swagged panels that surmount them, the third-floor windows (opening to an ornamental iron balcony) announce an elevated piano nobile facilitated by a passenger elevator. A lively air, at once formal and festive, animates this facade, as befits its sources in English resort architecture.
