Homes Embracing Natural Light｜Custom Home Examples by Architectural Offices18Picks｜A Residence Where Light Changes Over Time

Author: Qurasuki Editorial Department

Homes rich in natural light enable occupants to sense the passage of time and seasonal shifts indoors, imbuing daily life with vitality. Daylighting strategies encompass a multifaceted approach: planning openings based on the solar exposure characteristics of each orientation; employing skylights and high-side windows to deliver light deep into the plan; utilizing light courts; and selecting finish materials with attention to reflection and diffusion. Furthermore, designing eaves and overhangs that block summer solar gain while admitting low winter sunlight is essential to a comfortable luminous environment. Against the backdrop of site conditions and lifestyle requirements, explore these architectural firm case studies in which light transforms beautifully from morning to evening.

Homes Embracing Natural Light

House in Toyoshiki

Yu Architectural Design Studio

This is a compact residence of approximately 26 tsubo of total floor area, built on a flag-lot in Kashiwa City. In a site surrounded by neighboring houses, a second-floor living room was adopted to maximize daylight. The openings facing the balcony are articulated with angled walls that skillfully control sightlines, achieving both brightness and privacy. A mortar-effect siding exterior is harmonized with a warm interior that leaves beams and columns exposed. By incorporating DIY elements to keep costs down, the house realizes a rich way of life through ingenuity and creativity.

Two-Generation Courtyard House on a Narrow Irregular Lot

Archiplace

A fully separated two-family residence located in a densely built residential area of the city center. Given the condition of an elongated, irregularly shaped site surrounded by buildings on three sides, a courtyard and deck terrace are placed on the southwest side—the only side with an unobstructed view. By designing it as a three-story timber-framed courtyard house, an open living environment that admits natural light and natural ventilation is achieved while screening sightlines from the surroundings. The home accommodates a dual-income couple who enjoy music and an aunt who lives with a beloved cat; it respects each household’s way of life while enabling occupants to feel close to nature within the urban context.

Tower of Light and Wind

Kumi Inoue Architects

A residence located in a residential neighborhood in Ikuno Ward, Osaka. Street-facing openings are minimized, with a plan that admits daylight and breezes from above the central staircase. East–west skip floors introduce level changes whose gaps allow air and light to circulate. In winter, warm air beneath the floor is circulated via the staircase to moderate the interior environment. The garage and the earthen entry (doma) are configured as an integrated space that screens views from the exterior, creating a calm dwelling that harmonizes with existing reclaimed-wood furniture.

Residence in Moriguchi

In-Ex Design Co., Ltd.

Situated close to a shopping arcade, this is a “windowless house” built on a mere 19-tsubo hexagonal site. The building wraps around the full perimeter of the lot, creating a quiet interior world cut off from the street’s bustle. Exterior spaces are inserted at both ends of the two-storey volume, and living areas are arranged along the circulation that connects them. Without distinct room partitions, the spaces are loosely zoned by use and activity, accommodating the occupants’ flexible patterns of living. An inventive urban dwelling, it feels closed yet conveys a rich sense of spatial expansiveness.

Koshien House — Renovation Beginning with Solid-Wood Floor Restoration

Tokuhiro Norimatsu Architect

This residence carefully excavates the latent charm of the building through the act of reconstruction. Private rooms were removed, and from a newly introduced raised platform the living room can be viewed through the window, creating a layout that produces a gentle connection not only within the interior but also mediated by the exterior. The columns that serve as the spatial anchors have been assigned new roles, and while inheriting the time and memories the building has accumulated, they quietly overlay contemporary living and performance. It is a home imbued with the deep allure unique to reconstruction.

Message from the sky II

Hirotaka Sato Architects

“MESSAGE FROM THE SKY 2” is a residence that incorporates the ever-changing expressions of the sky into the architecture, allowing the passage of time to be experienced in everyday life. A vertical circulation route is positioned directly beneath the skylight on the third floor, guiding the gaze from the entrance toward the sky above the building. Reflections from half mirrors are layered into the design, projecting different expressions of the sky into the interior during the day and at night. The result is an abstract yet richly evocative space in which the presence of the sky can be sensed through light and reflection, even without looking directly upward.

3-Wall Fold House

ARCHIXXX Satoru Shinno Architectural Design

This home is located in a quiet residential neighborhood in Nagoya, Aichi Prefecture. A windowless white wall faces the busy road, ensuring security and privacy. Meanwhile, a machiya-style courtyard is positioned at the center of the house, bringing natural light and fresh air into the living room at the rear while blocking views from outside. By clearly defining the areas to be closed off and those to be opened, the design creates a bright, well-ventilated and tranquil living space that responds to its urban surroundings.

A House Living in Harmony with Wood

Ringo Studio, First-Class Architect's Office

A residence situated in the scenic conservation district of Ōmiya, connected to tranquil nature. Under a site‑coverage limit of 40%, a simple square planimetric and volumetric composition was employed to create a generous spatial extent. Openings boldly capture the light and breezes passing through the private road to the south and borrow the landscape of the neighboring house. Internally, a skip floor with a 1.5‑storey intermediate level secures floor area and openly links the spaces of differing heights. The spaces, finished in locally sourced Nishikawa cedar, form a beautiful building—underpinned by classical methods—where exterior and interior comfortably meld.

House on a Sloping Street

Tenkosha First-Class Architects Office

This is a new residence planned in a quiet residential neighborhood of Shiroyama, Odawara City, Kanagawa Prefecture. Although the site is approximately 93 tsubo in area, road access is narrow and on a steep incline, so work began with widening the entrance. To ensure safety against the cliff on the west side, a high foundation and a setback were provided, and the building was located at the center of the site. Existing trees were thinned while retaining a persimmon tree as a symbol of the garden and daily life. Apitong timber was used for the exterior cladding and deck to harmonize with the surrounding trees. A double‑height void and large openings gently connect interior and exterior, creating a soft residence enveloped by the tactile quality of wood.

A House with “Ma” Connecting Two Households

AtelierMA

Located in a residential neighborhood in Ota City, Tokyo, this two-generation house allows the parents’ and children’s households to live together while maintaining a comfortable sense of distance. By combining multiple volumes, the design gently separates each family’s living domain while creating a sense of unity as a single home. The centrally positioned balcony serves as a shared space where family members naturally gather and deepen their interaction. Balancing independence with connection, the house fosters rich relationships that span generations.

「ha」 hosaka hironobu architect associate

This residence, realized through meticulous deliberation, is imbued with a quiet dignity. Strategically placed picture windows gently link spaces, blurring the boundaries between interior and exterior and between near and distant views, thereby generating a rich sense of depth. At the heart of the home is a three‑story atrium, creating an impressive volume in which light and shadow shift over time. Details refined with care down to the smallest elements shape the very atmosphere, delivering a refreshing living environment where light and breezes circulate comfortably.

House of Four Pavilions and an Alley | Four-Corner House

Yoshihiro Yamamoto Architects Associates

This house is located on a hillside in Sakai City, Osaka Prefecture. Within an 8.1‑meter square house-form volume, four functionally distinct, smaller house-like volumes are arranged, creating a cruciform interstitial space with alley-like distortions between them. The spaces open and close while remaining continuous, generating diverse relational conditions for daily life. The exterior presents an abstract house form clad in the tactile, representational texture of charred cedar, while the interior, despite a complex skip-floor configuration, is conceived as a simple white cube.

House in Endo

Kurashi no Jōzōsho

Responding to a site enclosed by residences on all sides, this dwelling brings light and greenery into a U‑shaped courtyard at its heart. Employing an east‑facing garden strategy to capture morning light from the east while securing daylighting from the south, the design achieves a sense of openness that belies its total floor area of 26 tsubo (approximately 86 m²). A deck level with the living room provides a pleasant, outward extension of the living space. Trees such as Japanese maple (Acer palmatum) and olive animate the seasons, completing a home in which the family can peacefully spend the years together.

Machiya in Machiya

Takeshi Hirobe Architects

This house introduces a courtyard into a densely built-up shitamachi site, as though the upper floors had been carved away. Even in an environment where opening the house to its surroundings is difficult, it creates an “interior exterior” that brings in light and air, filling the living spaces with abundant brightness. The stairs and passageways surrounding the courtyard continue like one large stair hall, and living rooms and bedrooms emerge as its landings are expanded. Within a highly insulated and airtight enveloped space, finely textured walls and built-in furniture are layered together in a home that makes meticulous use of every limited dimension, like a product.

friends

*studioLOOP Architects

This house for a couple and the mother balances family connectedness with rich, personal time for each resident. The LDK and second-floor loft are integrated, while large openings facing the south garden and windows framing views of the sky draw in natural light and create a sense of openness. A road-bike maintenance space is provided near the entrance. Alongside the cherry tree in the garden, the house will grow over time, adding a new scene to the surrounding townscape. The low-eaves white exterior quietly expresses harmony with the town.

House at a T-intersection

Yosuke Tomiya Architectural Design Co., Ltd.

A two-family home that replaces two residences where generations of families had lived for many years. Taking advantage of the site’s location at the end of a T-junction, the design creates an open living environment in the city through openings that allow views to extend over the street. A large window beyond the curved wall brings the surrounding townscape and sky indoors, while the L-shaped building layout delivers soft light to each room. With circulation planned to accommodate life with a dog and a custom-built bench in the second-floor LDK, this is a home designed to foster rich, shared moments across generations.

House Behind the School Building

an Archi-Lab. First-Class Architect Office

This is a reconstruction plan of the long-occupied family home so that a mother and her daughter can live there. Under the severe condition of a narrow 19-tsubo site with an elementary school building pressing on the south side, a small garden and a nure-en (verandah) were provided on the southern side of the site to bring light, wind, and a sense of depth into the residence. Internally, multiple living areas were arranged according to degrees of privacy and openness, realizing a composition in which light moves throughout the entire house. While engaging carefully with the surrounding environment, the design cultivates a rich residential quality within a limited footprint. The phrase "a house you want to come home to" testifies to that comfort.

Mikuri House

Yoshihiro Ito Architect & Associates

Set in a quiet residential neighborhood, this home takes advantage of the seasonal greenery spreading across the grounds of a nearby shrine as borrowed scenery. Expansive, ceiling-height openings on the north and south sides bring the rich landscape and natural light into the interior. By allocating the limited budget appropriately and providing deep eaves and places open to the outdoors, the design enables a spacious way of living even within a small home. Wooden fittings and shoji screens create a soft light and lend the house a beautiful presence even when it is closed to the outside.
