A tracery of arched doors and windows opens into this pristine garden of colorful water-conserving plants that complement the architecture and the residents’ aesthetic. Stepping stones wander from a custom curved heated-seat bench. A second spare stone bench at the end of the path invites a shift in perspective. The view from the second story of this custom-designed Carmel cottage looks out across the garden, planted around mature trees, giving the backyard space a secret garden sensibility.
