Construction Phase
During construction, Cadaxx Design closely coordinated with engineers and builders to ensure all design details were executed to plan. Structural framing, exterior finishes, and custom millwork were completed with precision. The construction phase focused on material quality, site efficiency, and achieving the rustic-modern character envisioned in the original design concept.
Completed Project
Now fully completed, the home showcases the intended rustic-modern aesthetic. Natural stone cladding, dark vertical siding, and timber columns create a warm yet refined exterior. Careful attention to proportion, detailing, and material contrast gives the house a strong street presence while maintaining harmony with the surrounding neighborhood context.
