「目目裏山」位於台灣新竹縣竹北市住宅區，基地面寬二十四米、深二十六米，兩側緊貼鄰棟住宅側牆，南側面向都市巷道。

依基地尺度及鄰近住宅型態，採取小社區架構，置入內凹中庭及車道，以其為中軸鏡像地配置形成左右各三戶住宅單元，正面兩戶（A-type）朝向都市，後四戶（B-type）彼此面對面。

住宅單層7×8.5公尺方形範圍內，樓梯被推向平面中心，開啟單層平面的兩面性，由此帶動住宅內部活力。

樓梯被賦予組織空間的角色，以繞行路徑串起不同空間，透過其可塑性應對空間之公共與私密狀態，時而封閉、時而開放或延伸，與周邊空間形成新的關係。人的生活緊緊地依附樓梯而展開與累積。

沿著細窄樓梯進入二樓及三樓，這裡是一處由內部打開來的空間，日常生活交會的核心場景。餐桌不僅僅作單一功能使用，在廚房、夾層與樓梯的陪伴下，它及其周邊成為家庭各種活動的發生場所。垂牆、洞口、樓梯側牆及側柱，在空間中彼此相遇與融合，製造多層空白面域，在流動空間中注入隱私感，以及讓人轉換的抽象性。

正立面馬賽克牆面與規律的內凹陽台，鋪陳出整體扁平的面感與均質的集體基調，以外部構成拉出與都市鄰房的距離感。背立面由鄰棟側牆向內退縮，留出後天井，為窄棟距的住宅內部帶來深度與靜謐的背窗面。

露台盒子、陽台與簷板複合體滑行般地懸出，在集體架構中樹立家屋獨立性格。在核心生活空間，它於調控內部與外部間微妙界面：簷向外延伸卻又向內包覆，打開水平市景；露台牆體將外部納入內部，帶來如後院般的光景。在同一空間裡，感覺到兩面不同的雨。

The Mirror Mountain project is located in a residential area of Zhubei City, Taiwan. The street front of the site is 24 meters in width and 26 meters in depth. Two sides of the site boundary border are adjacent to neighboring houses with the southern end facing the street.

Considering the scale of the site and the surrounding residential typology, the architecture design adopted the approach of a small community of structures creating a courtyard and drive way. All living units revolve around the courtyard, including the two street front residential units (A-type), and four facing units around the central courtyard (B-type).

The typical floor area of the residential units measures 7 meters by 8.8 meters. The staircase is placed in the middle. Allowing the front and back spaces to enjoy natural light and generate more of activities within the domestic interiors.

As the generator of the spatial structure, the staircase meanders between different spaces and weaves between levels in the residential unit. The flexible relationship between the stair and the private/public nature of spaces allow each spatial encounter to shift between closeness, openness, or extensiveness forming new spatial relationships as one moves up the staircase. Life within the house is tightly connected to the staircase, expanding and accumulating everyday experiences.

Walking up the narrow staircase and entering the first and second floors of the unit, new spatial experience open up from the inside out. The stair becomes the core for everyday social interactions within the household. The dining table designed for multiple purposes. It is considered as a site that sits in between the kitchen, the mezzanine and the staircase. This space acts as the gathering place where family events and activities happen. Vertical walls, openings, stairwell and the singular supporting column by the staircase meet and merged with one another within the space. This produces experiences of spatial layering, injecting moments of privacy within the fluid space or introducing moments of abstraction in spaces.

The mosaic wall on the street facade and the regulated concaved balconies create a sense of flatness and a kind of even visual tone. The housing blocks utilized their external structural compositions to fit in better within the surrounding urban housing typology. The back-elevation of the blocks set back from the neighboring walls, leaving space for light wells. This provides further depth to the interior and some quiet views for the back windows.

Terrace boxes and balconies in combination with eaves cantilever from the facades, establishing a unique composition between housing units and the overall collective structure. In terms of the core living value, these elements become the intricate boundaries that regulate the inside and the outside. The eave slopes down as it extends outward, opening up the city view horizontally. The terrace walls combine external conditions internally, inviting the backyard-like space and atmosphere, creating a duo experience between two facing elevations within one singular space.
