這是一棟坐落于自然環境優越之地的住宅，面朝櫻花樹成蔭的步道（原為小川，后改為暗渠），擁有良好的視野、通風和采光條件。為了回應業主“每天在日出中醒來，仰望天空，感受自然光和風”的愿望，我們對住宅的構成進行了深入思考。

This residence is built in a natural environment blessed with scenic views, ventilation, and sunlight, facing a row of cherry trees planted over a culverted stream. The design was developed to reflect the client's desire to live in harmony with nature—waking up with the sunrise and experiencing natural light and breeze while looking at the sky.

考慮到住宅南側緊鄰綠道與櫻花林，設計中力求最大程度地向南開敞。同時，受日本北側斜線高度限制的影響，北側建筑需相對降低高度。于是我們意識到，在南北方向上設置不同的層高是一種合理的建造方式。

Considering that the south side of the residence is adjacent to a greenway and a cherry blossom forest, the design strives to open up as much as possible to the south. At the same time, due to the height restrictions imposed by the north-side setback regulations in Japan, the buildings on the north side need to be relatively lower in height. As a result, we realized that adopting different floor heights in the north-south direction is a reasonable construction approach.

東西方向上塑造出開闊而延展的空間的同時，在南北方向引入錯層結構，將不同高度的水平面嵌入建筑中。我們嘗試將這些由高低差產生的空隙視為光線、風，以及人的流動路徑，以此來打造一個舒適宜人的居住環境。

The horizontal planes are arranged with level shifts, creating gaps that act as pathways for light, wind, and movement—aiming to cultivate a comfortable and pleasant living environment.

玄關設有嵌飾天然小石的土間區域，與室內無縫連接，細致而溫馨地迎接家人和來客。

The entrance features a seamless transition from a traditional earthen floor embedded with natural pebbles, warmly welcoming family members and guests with care and intention.

正面設置了一扇由手工精心拼貼而成的漆涂和紙門扉，并配以經過名栗加工（Naguri）的把手。以楮紙制成的和紙涂上漆后，門扉不僅展現出獨特的質感，還提升了強度，隨著時間的使用更能展現出深厚的風味。

At the front, a door adorned with hand-applied lacquered washi paper and a handle crafted with naguri carving technique sets the tone. The washi, made from kōzo (paper mulberry), is coated with lacquer, creating a unique texture that not only enhances its durability but also deepens in character with use over time.

把手則是由栗木與胡桃木兩種木材交替拼接成六角形，再施以名栗加工，使其在不同角度展現出豐富的表情，同時也帶來富有趣味的握持觸感。

The handle is composed of alternating pieces of chestnut and walnut, joined to form a hexagonal shape. Through the naguri technique, it offers a variety of expressions depending on the viewing angle and provides a tactile pleasure when gripped.

從玄關上來之后，地板采用了經過名栗加工的實木材料，不僅在視覺上呈現質感，更通過腳下的觸感傳遞出歸家的安心感。

At the top of the entrance step, flooring finished with the naguri carving technique is used, offering not only visual warmth but also a comforting tactile sensation underfoot—instilling a sense of homecoming from the ground up.

樓梯處柔和的自然光從北側上方灑入，貝松實木的踏板、銅色的扶手，以及工匠細心纏繞的藤制扶手的質感，共同營造出溫馨柔和的空間氛圍。

Soft natural light filters in from the upper north side of the staircase, gently illuminating the space. The solid Douglas fir treads, copper-toned handrail, and the finely hand-wrapped rattan railing by skilled craftsmen all contribute to a warm, enveloping atmosphere through their rich textures and natural materials.

居住中最長時間使用的客廳、餐廳和廚房（LDK）被安排在二樓南側，面向櫻花林道，擁有超過13米的寬闊開口。

The living, dining, and kitchen area—where the family spends the most time—is placed on the south side of the second floor, offering a view of the cherry tree-lined street through a frontage of over 13 meters.

為了讓五口之家寬敞自在地生活，我們設計了無柱結構空間。通過避免在大梁的垂直方向設置小梁，使來自北側天窗的自然光能夠柔和地灑滿天花板，整個空間在一天中都能充滿自然光線。

To allow a family of five to live comfortably and openly, the structure was designed as a column-free space. By avoiding the use of secondary beams perpendicular to the main beam, natural light from the skylight on the north side spreads gently across the ceiling, creating a space that can be enjoyed throughout the day in natural light.

為了實現最大12米跨度（客廳餐廳跨度為7.7米）的木結構無柱設計，我們采用了將105×270毫米的大梁夾著半割的60×240毫米梁，按910毫米的間距組成剪刀式桁架（Scissors Truss）；在與其垂直的天窗部分則設置維爾恩德爾桁架（Vierendeel truss）。通過這種設計，水平力由同時作為飾面層的屋面板承擔，從而形成了無小梁、結構規整且堅固的大屋頂。

To achieve a column-free wooden structure with spans of up to 12 meters (7.7 meters across the living-dining area), a scissor truss system was employed. This consists of 105×270 mm main beams sandwiched by halved 60×240 mm members, arranged at 910 mm intervals. At the intersecting skylight area, a Vierendeel truss is incorporated, enabling the roof to resist horizontal forces using only the sheathing boards, which also serve as the finished ceiling. The result is a clean, refined, and robust large roof without the need for secondary beams.

環境設計方面，以被動式節能設計為基礎，建筑結構通過檐口和墻體遮擋陽光直射，具備充分的隔熱性能，最大化利用自然通風和自然采光，

From an environmental standpoint, the design is based on passive principles, incorporating deep eaves and wall configurations to block direct sunlight, along with high insulation performance to ensure thermal comfort. Natural ventilation and daylight are maximized throughout the home.

一、二樓南側均設有大面積開口，引入南北方向穩定流動的風，同時結合重力通風原理，開啟屋頂頂部的天窗，從一樓吸入風的氣流，實現自然通風效果。

Large openings are placed on the south side of both the first and second floors to capture prevailing north-south breezes. Additionally, by utilizing stack ventilation, opening the skylight at the roof's peak creates an upward airflow that draws in air from the ground floor—establishing a natural and efficient system of ventilation throughout the building.

在寒冷季節，設計通過吸取屋頂頂端積聚的暖氣，送至一樓窗下及浴室等較冷區域，使暖氣在整個房屋內循環流動。

In winter, the design allows warm air that accumulates at the roof’s peak to be drawn in and directed to colder areas such as beneath first-floor windows and the bathroom. This creates a circulation of warm air throughout the house, helping to maintain a comfortable indoor temperature and reduce cold spots.

在客廳、餐廳和廚房（LDK）與室外之間設置了無縫連接的露臺，拓展了起居空間的延展性。保持面向櫻花林的開放視野的同時，也設計了可調節視線遮蔽度的窗簾，以滿足夜間對隱私的需求。白天透光的布料隨風輕盈飄動，夜晚則通過增加布料密度形成不透明的隔斷，使露臺與LDK融為一體的空間感得以延續。

A terrace is positioned to seamlessly connect with the LDK, extending the living space outward. To maintain openness toward the cherry tree-lined street while also addressing nighttime privacy, custom curtains were designed. During the day, the light, translucent fabric gently sways in the breeze, preserving a sense of openness. At night, the fabric's density increases to create a more opaque boundary, allowing the terrace to become an integrated, private extension of the LDK.

浴室緊鄰露臺布置，脫衣室和浴室內也能灑入柔和的自然光，并且設計得讓人能夠感受到微風。通過將浴室樓層降低于露臺水平，有效阻隔了來自綠道的視線，同時保證了較高的天花板高度，使蒸汽能夠順暢上升并排出，避免積聚。

The bathroom is positioned adjacent to the terrace, allowing soft natural light and fresh air to flow into both the dressing area and the bathing space. By lowering the floor level of the bathroom relative to the terrace, the design blocks views from the greenway while securing a high ceiling. This not only provides privacy but also allows steam to rise and dissipate effectively, preventing it from lingering and creating a more comfortable bathing environment.

浴室采用十和田石與檜木，展現出豐富的肌理與色彩層次，并散發自然的芬芳。在沐浴時打開窗戶，讓四季之景隨風入室，營造出一個能夠溫柔包容身心、予人療愈的場所。

The use of Towada stone and hinoki cypress in the bathroom offers a rich sensory experience—through their varied textures, natural hues, and calming fragrances. With windows that open to the outdoors, the space is designed to allow one to bathe while feeling the changing seasons, creating a soothing retreat that nurtures both body and mind.

三個孩子的學習區并未作為獨立的封閉房間設置，而是安排在跳層下沉約70厘米的空間中。這樣既通過腰墻將其與LDK分隔開來，又能讓空氣流通，讓家庭成員之間共享溫馨的氛圍，營造出既有區隔又互相連通的學習環境。

The study area for the three children is intentionally not enclosed as separate rooms. Instead, it is positioned about 70 centimeters lower than the LDK on a skip floor, creating a semi-separated space divided by a low wall. This layout maintains a sense of connection and shared atmosphere with the family, while still providing a dedicated zone for focused study.

業主是一位隨日出而起、日落而眠，生活與自然緊密相連的人，因此我們將臥室布置在朝陽溫暖照射的東側。障子柔和地擴散晨光，質感豐富的硅藻土墻面在四周環繞，這些都使自然光溫柔地包裹整個房間。

The homeowner lives in harmony with the natural rhythms of the day—waking with the sunrise and resting as night falls. In response, the bedroom was placed on the east side, where the morning sun gently filters in. Shoji screens diffuse the sunlight softly, while the textured diatomaceous earth walls reflect and wrap the space in natural light, creating a serene and calming atmosphere to begin each day.

在充分享受外部自然環境恩惠的同時，室內也遍布自然素材，營造出充滿工匠手工溫度的空間。我們希望這所房子能隨著歲月沉淀出獨特的質感，見證家人寬厚而溫暖的成長。

While fully embracing the blessings of the surrounding natural environment, the interior is adorned with natural materials that reflect the warmth of skilled craftsmanship. The space is designed to develop character and charm over decades, growing alongside the family and quietly witnessing their journey together.
