Indoor-Outdoor Transitions & Threshold Architecture
Dissolving boundaries between interior sanctuaries and outdoor landscapes.
Architecture achieves its highest potential when the distinction between inside and outside disappears. Rowui specializes in threshold engineering: designing floor finishes that flow seamlessly across flush door tracks onto outdoor terraces, covered exterior loggias that extend the living room outdoors, and ceiling planes that reach outward to draw the garden inside.

Scope & Core Competencies
Our approach to indoor-outdoor transitions & threshold architecture integrates architectural theory, physical constructability, and regulatory code requirements.
- Flush-floor zero-threshold drainage and sub-sill engineering
- Motorized multi-panel pocketing glass sliding systems
- Overhanging protective soffits with integrated outdoor heating
- Continuous stone and tile flooring transitions without tripping edges
- Corner-less opening glass systems for uninterrupted panoramas
- Retractable weather and insect screen integration
Residences in warm, temperate, or scenic microclimates where indoor-outdoor entertaining is central to the lifestyle.
