Read Full Project Description

Inspiration came quickly from old growth silver-birch forest, the drama of the cliff-edge setting and breathtaking views. Having enjoyed Niseko’s four distinct seasons, I evolved an architecture that enhanced this unspoiled alpine setting while protecting its wonder. The quiet of the forest and charm of its burbling stream demanded planning that ensured privacy for each villa’s onsen, stunning views as well as direct access to the meandering river valley below. Saving every old-growth tree in this nature reserve was a prime objective, consistent with sustainable design principles employed throughout.

Unlike anywhere else in Hirafu’s middle village, Corniche estate’s 22-meter height zoning allows multiple floors with double-height ceilings.  Expansive floor-to-ceiling windows enable celebration of light and space: the ultimate signature of true luxury and commodious living.

Broad, fully equipped and sheltered sky terraces are designed for all-season entertaining, exploiting spectacular panoramic mountain and forest views. Each level from sky terrace to spa is easily accessible by elevator, enabling convenient enjoyment of every amenity.

Abundant use of stone, timber, darker colours and tones integrated with soft, indirect illumination is essential to complement the ever-changing quality of light and alpine beauty of Niseko’s four distinct seasons. Corniche is timeless contemporary architecture that marries awe-inspiring nature in a secluded forest enclave with a vibrant village lifestyle.
