Cubo Design Architect Builds a House Around Light on Water

In the coastal terrain of eastern Japan, where salt air drifts through bamboo groves and mandarin orchards slope toward the Pacific, Cubo Design Architect conceived 10M, a residence that makes water its organizing principle. The home features 56,000 square feet of gently inclined land, creating the stage for an architectural project structured entirely around its 65-foot swimming pool, which functions less as recreational amenity than as generator of light, rhythm, and atmospheric presence.

Modern living room with beige sofas, a wooden coffee table, and an open wall leading to a patio, pool, and outdoor lawn with lounge chairs and a view of the ocean.

The pool establishes the compositional spine, aligned deliberately with the citrus grove to the south. The architecture unfolds from this axis, all while keeping water as the home’s focus. The surface of the water catches fragmenting sunlight, creating a sparkle perceptible from every interior space. The manipulation of spatial sequence draws directly from Sukiya-zukuri architecture, the restrained aesthetic tradition formed from Japanese tea ceremony spaces. The entry unfolds through compression and release – a cave-like approach tunnel opens to a dim gallery, then through wide doors into the pool-facing expanse. The design forces adjustment of the eyes, amplifying perceived luminosity through controlled contrast.

Modern dining area with a long table and chairs, pendant lights above, and large open doors leading to a pool and garden view; several boxes are stacked near the wall.

The embedded tea room pushes this material and atmospheric precision through the function of the residence’s terminus. It borrows views into neighboring bamboo while deploying traditional elements – bark-wrapped columns, natural plaster walls, compositional gestures sourced from the 16th-century tea master Sen no Rikyū – with the architects creating their own reinterpretation.

A dimly lit, narrow hallway with smooth brown walls, arched entryway, and a single stone bench along one side, leading to a softly illuminated area at the end.

The pared palette and minimal detailing function as perceptual training, heightening awareness of environmental shifts that richer surfaces might obscure. Wind in bamboo, water ripples, bird calls, and distant surf are framed as primary content rather than backdrop. Supporting this domestic life are functional insertions handled with equal economy – wine storage, guest quarters, fitness space, all subordinate to the larger atmospheric project.

  • House of Shifting Sands

    Sited gently on the lower slope of a dramatic sixty foot high coastal bank and surrounded by miles of undeveloped Cape Cod National Seashore beaches and scrub pines is a warm, modern beach house that is more than just a place to enjoy uninterrupted ocean views and sea breezes. Our clients dreamed of a house that would work equally well as both a year-round family “camp” and also as a “thinking retreat” for collaborating with their colleagues. From the beginning of design it was critically important to us and to our clients – as well as the Town Conservation Commission and National Seashore representatives – that the house fit into its fragile site seamlessly. Our team responded with great care by designing the house to curve and shift softly with the natural topography and also by envisioning the new native and drought resistant landscaping growing back tight to the house as if both had always been there together. The main house is conceived of as a collage of overlapping, cantilevered planes and volumes that culminate in a large living / dining space defined by an asymmetrically arcing copper roof plane. Entry to the house is by way of a long ramp through what will in a few years be a thicket of native pines and bushes, then through curving cedar shingled planes. The inland side of the house is tucked into its shifting, sandy landscape and is comprised of cedar shingled planes that float above the ground and contain bedrooms, bathrooms, and the kitchen, and lower volumes of horizontal tongue and groove cedar boards that enclose bedrooms and a gathering space for teenage sons. On the Cape Cod Bay side, the house opens up through walls of glass to endless water views and heavenly sea breezes. In the middle of the house, just inside the front door, is an architectural “hole” that allows the house to breathe and cool itself naturally most of the year through its floor to ceiling awning windows, and which also provides views of the sky from a shady breezeway on the lower level. Along one wall of the hole is a trellis planted with evergreen and seasonally aromatic flowering vines.

Separated from the main house by a screen porch and contiguous deck, is a separate art / yoga / thinking studio that seemingly floats fourteen feet above the ground. Inside is a single large loft space as well as a full bath, and below is an open-air summer art studio and boat / beach toy storage, behind walls of wood slats and matching barn doors.
