Rurban Studio: Huanghua’an Hotel is a small hot spring resort located in the woodland in the east of Nanjing Garden Expo Park. It is adjacent to the No. 3 entrance of the park in the East and faces the huge mine across the valley in the south.

The hotel is named after the “huanghua’an geological section” in the north of Bangchui Mountain. Geologist Ding Wenjiang discovered the Late Permian Early Triassic geological section at the foot of Bangchui Mountain at the beginning of the last century. Since then, this geological section has been named “huanghua’an geological section”.

自然与地形 Nature and topography
In the overall planning of the park Expo Park, huanghua’an Hotel follows the land boundary of the current building group. In this site, red brick bungalows are hidden under tall Wutong trees, and the mountain road climbing the geological section truly records the traces of geologists’ activities here. Big trees and climbing paths constitute the most characteristic material memory of the site, and preserving these site information as much as possible becomes the most important starting point of design. We hope to sort out and inherit the humanistic and spatial memory of the huanghua’an site, continue the original atmosphere and behavior of the space while meeting the new space needs, and then transform it into a leisure resort full of mountain and wild interests.
▽场地原始状态 Original state of site
The climbing path running through the center of the site divides the building function into two, which is an unfavorable factor. In order to give consideration to practicality, the functions of the hotel are sorted out in three dimensions: first, the dynamic and static zones are divided on the plane. The west side of the original terrain is relatively flat is planned as a public space, and the hotel lobby, all day restaurant and other functions with strong public nature and large area are arranged; The slope on the east side is planned as a row of rooms that fall in turn according to the terrain, and various types of outdoor hot spring pools are arranged between the rooms and the mountains on the east side. In the vertical direction, the elevation of the base level of the mountain climbing Road should be properly raised, so that the functions of the East and west parts of the hotel can be connected under it, so as to ensure that mountaineering and activities in the hotel can be carried out simultaneously without interference.

▽从北侧看客房与环境 View of rooms and surroundings from the north side
The plane layout of the rooms on the east side retains as many trees as possible, continuing the original scene of the site. On this basis, public activities in the guest room area are all carried out around big trees. The elevation of the three outdoor soup pools is determined according to the location of the root elevation of Wutong. The hard pavement in the hot spring area is also as close to the location of Wutong as possible. It is hoped that it can provide residents with the opportunity to get close to the “aborigines” of the site.

坡度与坡法 Slope and slope method
Huanghua’an Hotel is located in the original natural environment. The foothills, woodlands, flat valleys and cliffs can summarize the characteristics of its surrounding environment. In such environmental hints, the posture of the building naturally tends to dialogue and symbiosis.
▽建筑与环境 Architecture and Environment
The land used for Huanghua’an Hotel is long from east to west and short from north to south. The gradient of nearly 13 ° causes a height difference of about 12m between the north and south ends of the site. Based on the consideration of symbiosis, the overall contour of the building roof continues the trend of long slope coverage on the site, and the inclination of the roof is basically the same as the slope of the site, so as to maintain the harmony between the building space and the environment; In order to eliminate the abrupt feeling caused by the excessively long slope top in the natural environment, and at the same time take into account the needs of guest room capacity, traffic and landscape line of sight, the volume of guest rooms is reduced step by step, and the layout of building section presents local mountain architecture. At the same time, due to the avoidance of Wutong trees in the site, the three groups of guest room units also moved in the east-west direction. In combination with the public space in the lobby on the west side of the hotel, the staff activity base of Huanghua’an Hotel is located at ± 0.00, 5.00, 8.90 and 12.80 elevations respectively. Each part is connected and transferred by stairs and vertical elevators. Through the change of height difference and the opening on the facade and roof, the residents can feel the existence of section and mountains, and experience the natural interest between mountains and fields.

正面与侧面 Front and side
Chinese traditional slope top buildings have obvious positive characteristics, that is, the scale of surface width is much larger than the scale of depth, but it is slightly alleviated in gardens and residential buildings. The cultural attributes of Chinese traditional slope tops are also different from those of western slope tops. China takes the slope as the front, while the west takes the gable as the front. Especially in Chinese traditional courtyard style buildings, from the perspective of human beings, all section is front.
▽立体流线的交织 The interweaving of three-dimensional streamline
The entrance of Huanghua’an Hotel is still developed in a positive way, but the physical space on the central axis is placed in a virtual place, and is converted into a lateral entrance, a visual corridor and different openings facing the surrounding scenery by using different elevations of the terrace. On the scale of proximity, because the planned road and the hotel site show a close parallel relationship, when tourists keep approaching the Huanghua’an Hotel along the road, the depth of East-West horizontal extension becomes an inherent feature of the site. Therefore, in the facade treatment of the hotel facing the road, the cornice of the building is pressed as low as possible to conform to the horizontal trend of the environment, and the broken line turning on the plane breaks the rigidity that may be brought about by the “一” shape, so that one corner of the building shows a slight upward lightness, which contrasts with the “flying stone” above the pitched roof to achieve a balance between the horizontal and vertical of the front.

▽屋顶下的穿越空间 Traversal space under the roof
As for the treatment of slope top surface, due to the complexity of electromechanical pipelines in hotel building types, we choose to conceal the structural order of the top surface, convert the traditional slope top structure into an abstract contemporary spatial logic characterized by points, lines and surfaces, and make the vertically distributed components supporting the top surface become the visual focus in the space. Through the fine design of cross-shaped plane steel columns and T-shaped section curtain wall keel, It weakens the sense of volume of vertical components. The combination of broad eaves and transparent glass curtain walls strengthens the depth of space. The roof is like a floating leaf, which can be integrated into the atmosphere of the site.

材料与时间 Materials and time
The superior environment and the functional setting of the hot spring hotel make it possible to comprehensively mobilize physical sensations such as vision, hearing and touch. What we can do is to build an open building to blend the mountains, trees and artificial environment. The space corridor, which is as open as possible, has narrowed the distance between people and nature and provided tourists with rich experience in the change of seasons. The outdoor hot spring pool is hidden under the slope top and Wutong trees. You can sit or lie and watch the stars at night. In terms of building material selection, the hotel has determined the principle of using recycled red bricks as the main materials for the internal and external walls of the building at the beginning of the design. Red bricks are the main materials for the original bungalows on the site, and are also one of the few artificial traces on the site. The recycled red bricks from the old houses leave a memory of time and also have the characteristics of symbiosis with the environment. The selection of pitched roof materials also continues this idea, and shingles are more sensitive to the environment. In terms of performance, the water absorption expansion and saturation of wood fiber will reduce the possibility of further rainwater penetration into the room, and the shingle can cope with the humid and rainy climate in the South; In terms of effect, red cedar shingles will enter the aging process with the sun and rain after installation, and gradually fade from the original log color to a natural mottled color, which is easier to integrate with the environment. We hope that Huanghua’an hotel will become a local building, grow together with the environment in the years, and eventually become an inseparable part of the site memory.
