1. Compact in the Green The building layout is designed to be well-organized and compact, situated in the middle of the site in order to transform setback area around the building into a continuous large permeable green open space. This lets the green area acquire 50% of the site, suiting properly with the volume, shape and form of the new building. Besides the graceful landscape scenery and architecture, the project will make help cooling down the city, making it be more pleasant and appropriately maintaining ecosystem.


2.

Walkways and bike lanes are provided to maintain users’ safety and nice environment.


3.4 The underground network and parking lots are outlined along project layouts and structures of the new building above the ground which will make the structures uncomplicated, economical and gain a huge permeable area all over the site. LOVE BY HERITAGE Conservation of Local and Organizational Identified Art and Architecture With the simple L-shaped planning along X-Y axis, the new building is capable of holding all the required function. So the KongPassadu building (1948) and the Phahonyothin building (1952), which are important historical buildings and landmarks of the neighborhood and organization can be conserved. Conservation and Adaptation The Kong Passadu building and the Phahonyothin building will be maintained with the authentic beauty of structures, materials and architectural details.

The Connecting Between the Old and the New Continuity Harmony – Contrast New building is an extension that respects the harmony of axis, direction, size, shape and form of two existing historic buildings, keeping the simple geometrical rectangle. The new building design represents reality of the era, showing architectural concept, building technology, structure, material, building system. The difference of the new building would act as a background to emphasize the importance of the historical buildings as a main building, so that they would be a grand, grateful welcoming entrance, maintaining the Department of Highway’s identity.

1.Compact The working area are designed to be compact in order to shorten the distance between people, making everyone be closer and communicate more. Also, the building time and cost would be reduced.

2.Legibility – Permeability The L-shaped main transport network is clear and simple, compatible with the city pattern. Perpendicular branches along X-Y axis connect the areas together. Users can understand directions and remember positions of each division easily. This way, working here will be more efficient and the building will be safe to use.


3.Diversity Flexible The simple geometry plan can hold great diversity of work. Many sizes and types of work, including privacy requirement can be fulfilled by the flexible space provided. So the building surely can supports future changes in the organization well. WORK SPACES (Open office, team space, cubicle, Private work, lounge) MEETING SPACES (Small meeting room, large meeting room, meeting point) Support Spaces (Filing space, Storage space, Print and copy area, Pantry area, Locker area, Library, Waiting area)

4.4 Indoor Air Quality: IAQ Good and pure indoor air quality is provided by good ventilation which would keep pollution away. Carbon dioxide sensor system is used in order to control good air volume to match with carbon dioxide in the building. There is an air filter system to remove dust and bacteria in the air as well to retain good health for everyone.


4.5 Building Safety Avoid using toxic-dangerous materials. Fire protection technology and utilities are provided. Moreover, universal design are considered and applied all over the project.





Happy space and resting area; the source of creative and efficient energy With great diversity of type, size and historical context in order to hold a variety of following activities; Green space for recreation and environment Garden of big trees Green space on the setback area from main streets is a large, clear open space, connecting around the site continuously.
