Cashikou Village, Huairou District, Beijing
The site is located on a secluded corner of Cashikou village，which is located within a mountainous area embraced by a forest of chestnut trees. Walking towards the north one could reach the Great Wall and cliff inscriptions. The Cashikou Great Wall lies on the peak of the north-eastern mountain, which you can see from Cashijiang.

The site contains a farm house facing south, with low walls separating the inner and outer courtyard. The inner courtyard holds daily activities, while the outer courtyard has vegetable fields irrigated by mountain springs.
The principal house was built in 1970s, and its five-bay contains one living room and two bedrooms. It is 15.5 meters long while the roof is 4.5 meters tall, with a rather broad proportion. Its bricks, woodwork and roof are also all made with the finest local craft.
▼正房全貌，The principal house
Originally, the interior walls and ceilings were all covered with paper. Papers were also plastered on windows. With the use of heated kang, it can well survive a severe winter. The 80 cm projecting cornice ensures sufficient sunlight in winter and a cool interior in summer.

Renovation & New Constructions
As a small-scale building located within the large-scale environment with 50 years of history, we hope the building could have an intrinsic and sophisticated response to both its interior and exterior conditions. It is a great honor to renovate this supreme principal house in the mountains.

Besides the principal house, other buildings in the inner courtyard are all newly constructed. By sinking the courtyard, decreasing the depth of the building, and lowering the cornice, the design ensures the wideness of northern farm houses while maintaining the grandeur of the main building.

On the upper platform on second level between two blocks, one can enjoy a higher viewpoint.

New Construction·Dining Room
Looking out to the sinking courtyard, facing the old house and the east mountain, one could see the sun and its shadow shift overtime.

▼从书房回望，Looking back from the study
Looking out from the dining room to the courtyard through the lobby, the scene changes with season.
There is a gap between the study and the stone retaining wall of the northern village road, which helps create a central and dim corner.

New Constructions·Inner courtyard
The new steel plate on the grassland indicates the entrance to the wine cellar
In the inner courtyard, the remaining well tap and the water sink were all made by the home owner many years ago. We carefully add a new water channel between them.
We turned the original underground vegetable storage into a wine cellar, which can remain non-frozen in winter and cool in summer.

Renovation- The Principal House / Old House
With the self-made orange curtain, in early mornings in winter, the sunlight would be filtered through the curtain and fills the room with orange light, which would also combine into the old house.

New Constructions-Discovery in nature
The semi-open platform in air is located under a steel flower tank on the roof. The space is dim with great ventilation, where could clearly hear the sound of springs outside within this quiet village.

New Constructions-Ritual_Flower Tank, Water Sink
In the outer courtyard, the original vegetable sheds and fields are transformed into resting platform and gardens. On the east side, the original storage is changed into a workshop and a tea room.

On the platform of the outer courtyard, the water sink is lifted as if suggesting a sort of ritual.
The charm of space we are seeking is a kind of hidden dominating power and hazy “deep” communication.
