Stealth Is a Home Hidden Behind a Monolithic Facade in Tokyo

Tokyo is a city where architecture often competes for space and visibility, yet the STEALTH residence, designed by Satoshi Kurosaki of APOLLO Architects & Associates, takes the opposite approach. Rather than standing out, this private residence prides itself on discretion. Its solid exterior conceals an expansive interior that unfolds like an oasis, offering its residents the serenity and privacy of a luxury resort while being firmly rooted in an urban neighborhood.

From the street, the home appears to be a monolithic, box-like structure that cantilevers out over an all-black ground level, intentionally downplaying the entrance to the home and garage. STEALTH’s textured gray facade gives away little, intentionally shielding its interiors from prying eyes. The design prioritizes privacy, but not at the expense of light and openness. Instead, the architecture is carefully planned with interiors that open up, making the experience of moving through the home both surprising and rewarding.

Behind the front door, instead of a conventional foyer, the first view is of the owner’s car collection, including eight prized vehicles displayed in a built-in garage. This unconventional introduction transforms a functional requirement into a gallery-like setting. Sunlight from a north-facing window illuminates the cars, giving the space the feel of a well-lit showroom. The double-height entrance next to the garage amplifies the drama, with a sculptural spiral staircase winding though all levels of the living spaces.

Descending into the basement reveals another side of the house. Unlike many urban basements, this one avoids gloominess thanks to a sunken courtyard that delivers daylight into the gym. Adjacent rooms provide space for indoor golf practice and karaoke, emphasizing the residence’s resort-like feel with amenities. The subterranean level demonstrates how light, often scarce in Tokyo homes, can be harnessed in unconventional ways to create livable spaces.

The top floor serves as the public part of the residence. Here, an L-shaped living room unfolds around a semi-open kitchen and dining area, encouraging family interaction. Expansive glass walls line both the north and south facades, drawing in natural light while louvers filter it into a soft glow.

To the south, three floor-to-ceiling sliding panels transform the interior into an outdoor living space. Once open, the boundary between inside and out dissolves entirely, and the terrace becomes an extension of the home. A deep almost nine-foot overhang provides shade and weather protection, making the space usable throughout the seasons.

From the terrace, the infinity swimming pool is integrated seamlessly into the architecture and surrounded by lush greenery. At almost nine-feet deep, the residents can swim high above the city and feel like they’re away at a spa resort, offering a rare luxury in central Tokyo.

The second level shifts toward the sleeping quarters. Bedrooms and private spaces open onto a north-facing balcony. The primary suite features a walk-in closet and family bathroom, which includes a glass-enclosed bathtub overlooking the massive entrance hall. The children’s bedrooms are compact yet personalized with individual wardrobes. A study, which also overlooks the dramatic entrance hall through a glass partition, accenturates the home’s vertical interconnectedness, allowing even quiet spots to remain visually linked to the rest of the house.

  • 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.
