House of Bluff by Chaoffice: Transforming a Forgotten Wasteland into a Mountain Retreat
House of Bluff by Chaoffice transforms a neglected site into a playful mountain retreat, featuring geometric forms, sunken bath, and modular spaces.
Architects: Chaoffice
Nestled at the far end of a terraced landscape in Mentougou District, the House of Bluff began its life as a neglected, derelict property. Estranged from neighboring homes, the site had become overrun with wild plants, collapsed structures, and debris. Stray animals, birds, bees, and even palm-sized spiders had claimed the area as their own. Amidst the chaos, two resilient toon trees flourished, shielding the land like silent guardians.

Years later, the owner envisioned transforming this forgotten wasteland into a lively mountain retreat: a sanctuary blending relaxation, play, and nature. The redevelopment included five bedrooms, expansive indoor and outdoor spaces, a sunken open-air bath, a swing, and a slide, ensuring enjoyment for both adults and children.



Design Concept: Rejuvenation Through Geometry
The design philosophy draws inspiration from Lucas Cranach the Elder’s Fountain of Youth (1573), where a meticulously crafted sunken basin symbolizes rejuvenation amidst a rough landscape. Similarly, Chaoffice approached the site as a canvas of renewal, turning a chaotic, underutilized land into a playful, structured environment.
Working within a modest budget, the architects employed simple geometric forms to maximize spatial impact. Just as the painting juxtaposes youthful vitality against the hardships of age, the House of Bluff introduces clarity and order to a previously chaotic site.


Architectural Strategy: Multi-Level, Semi-Outdoor Living
The 300 m² two-level construction had to be sensitively placed within a larger 400 m² courtyard. The neighboring property’s imposing scale required a design that avoided creating an awkward visual relationship.
Chaoffice’s solution was to develop a series of semi-outdoor spaces and independent structures, generating a sense of grandeur despite the limited footprint. The design centers around cubic units of 4.5m x 4.5m, forming modular houses, porches, and 'hollow frames.' Some units were partially removed to improve light, enhance sightlines, and soften the building’s presence on the street, cultivating a playful yet cohesive architectural experience.


Layout & Spatial Experience
The main entrance, positioned at the northwest corner, descends into a double-height main living area. The kitchen, dining, and living rooms flow sequentially from south to north, while a sunken outdoor bathtub faces south, framed by exposed concrete structures. Concrete folding beams and vertical columns support the bath, aligned above the kitchen and central fireplace. This dynamic visual, flames beneath water, was so striking that the project was humorously considered to be named House of Hotpot.


Materiality: Contrast and Harmony
Externally, the house features a concrete frame with stone infill, grounding it within the natural surroundings. Internally, warm-toned stucco walls are complemented by wooden panels covering structural projections, creating a tactile and visual contrast. This interplay of concrete, stone, and wood not only enhances the aesthetic but also reflects the duality of structure versus maintenance, a subtle narrative embedded in the architecture itself.


House of Bluff: A Playground of Architecture
The House of Bluff exemplifies how thoughtful design can rejuvenate a neglected site. Through geometric simplicity, modular planning, and careful material selection, the project transforms a chaotic wasteland into a vibrant retreat, harmonizing nature, play, and living spaces.
