— Overview

Room to breathe.

The Hearth 1B1B separates sleeping from living without giving up the warmth that defines the series. A dedicated bedroom, a full bath and an open kitchen-living area make this a place to genuinely settle into — not just stay.

Warm wood ceilings, wide-band windows and a clean material palette make every morning feel intentional.
