OneScape：Vanke Time Center – San Yuan, the original Hainan Airline Office Building, is located at San Yuan Qiao, Beijing. The site has a prime location between Airport Expressway and East Third Ring. The renovation scope is the main office building along with the urban space around it which works as important interface between the site and the complex urban context.
HA office building has been in use for more than 10 years, the original site design cannot satisfy the needs of new business mode, emerging programs and current building tenants. The renovation aims to create a new urban image for the building, as well as a new site ambience to elevate the environment quality and to accommodate emerging programs.
The two diamond-shape office buildings have a strong character while the mature Scholar trees, Goldenrain and Ginkgo trees arrayed along the perimeter formed a very lush vegetation base. However, the main pedestrian entrance to the building was too cramped while the space between two buildings was messy and lack of focus. Vehicle and pedestrian circulation also needs redesign to improve safety and convenience while return the space occupied by parking to the public.

总体设计 Overall Design
The new landscape hasadopted an integrated design approach, responding to architecture’s new layout and façade, bringing indoor and outdoor space together, utilizing current planting base, embedding circulation into the overall layout, and eventually creating a diversified outdoor space in a high-end business setting.
▼项目总平面 Master Plan
▼设计策略 Design Strategy
Apart from business identity and circulation, the office landscape needs to provide spaces for various outdoor activities: gathering, meeting, relaxation, and even private moments. By preserving the scholar trees and golden rain trees on the west, an area with greenery, shades, and seats is created as a multi-functional park zone. Meanwhile, the narrow buffer zone on the north has been treated positively in a linear manner. Paths and pocket spaces weaving together with seasonal vegetation strips and gravel strips created space.
▼改造成本管控 COST Control
Due to the limited budget, cost control has been carried out through the whole site. The site has been divided into 3 zones for 3 different renovation strategies: total dismantle, protective demolition, and refurbishment. Meanwhile, existing site materials have been selected and protected during the demolition and reused in the new design.
南侧商务办公入口广场 High-end Office Image EntryPlaza
The lobby between two buildings behaves as a glass cube intruding into the major architectural mass,breaks indoor-outdoor boundary, reinforces north-south axis, and creates two focal point at the north and south ends. Landscape design addresses the two key nodes with special elements to create a relatively inward office space from being interrupted by urban chaos.
▼南侧入口广场 Entry Plaza
As the interface between site and its context, the entry water feature on the south forms a partial barrier to create a visual focal point blocking urban chaos from entering while allowing pedestrians to flow through.

▼叠水涟漪细节 Waterscape profile
The water feature section has presented an elegant concave curve toward office plaza, reflecting and collecting all the content and keep them on the site. Meanwhile it presents an undercut wall element toward city to form a firm but not blunt edge.
The concave surface facing architecture behaves as a cascading water feature with gradient terraces,widening up as the water flowing down. Such a gradient design responds to water’s own hydraulic characteristics, magnify the everchanging water dynamics.The stone module has been shaped in various sectional shape to control thewater spill outlet on each terrace to create a elevational water fall effectwith random rhythm.

北侧景墙 The feature wall
The feature wall on north end has inherited the module concept from south water feature, stacking brickblocks with different gray shades to form a wall element with subtle curvature. The design approach interpreted as pixilation of traditional material to form an interlocking and sliding relationship with stone walls and vegetation bands around, therefore, to create a modern landscape with traditional Chinese aesthetics.

北侧景墙两侧的休闲花园 North Garden
The linear garden next to feature wall on both sides aims to create a human-scale garden with certain intimacy. Lower flower shrubs and groundcover along with bamboo cluster have been utilized to create a quiet place for people to stop and savor the ZEN moment among busy office hours.
▼水处理 Water management
Along with the tree preservation, a rainwater filtration and recycle system has been designed and built on the north edge, an elevational low point on the site. Planting strips with water resistant vegetation and gravel strips are interweaving together to create a continuous linear water path to collect and cleaning the rainwater from the building façade and other part of the site. Rainwater will be collected through a perforated pipe underneath the filtration layer, and then be transferred to urban stormwater system.

西侧休闲林荫广场 West Tree Plaza
The original Goldenrain trees and Scholar trees preserved to form a semi-formal office plaza on the west. The existing root balls were higher than the existing road elevation and there was a vegetated slope on southwest corner. The new design works with the existing site condition instead of changing it. As a result: 1. A shaded plaza has been created under the existing tree canopies; 2. Direct the seat orientation and vision toward the vegetated area on southwest corner. The passages cutting into the grass slope are lines extended from building columns to form a more integrated relation between architecture and landscape.

▼改造策略大树保留 Tree Preservation
In order to protect trees, no excavation was done to bring the existing grade underneath trees to a lower level to match the rest of the site. Instead, landscape design extended the slope area underneath, added extra layer of protection mulch on top, and brought the slope to a gentler grade to increase the soil stability. New design adopted an approach of cutting into the slope at safe zones to create pocket spaces, adding metal retaining walls to create a modern touch. Seats and steps along pocket edges encourage people to enter the site and have more active and purposeful interactions with the preserved trees and the architecture.
