106. Download the design drawings for a 3-story office building with a total area of 1,080 m2

Looking at the overall drawing set, it is clear that this is a design proposal for a 3-storey office building, arranged in a straightforward and practical layout. The building is organized in a long rectangular form with evenly spaced structural bays, creating a balanced façade that is also easy to construct. This type of layout is quite common in small administrative buildings or office facilities because it offers efficiency while keeping construction costs under control.

• On the first floor, the layout mainly accommodates functional spaces such as storage areas and working rooms. The rooms are arranged along both sides of a corridor, allowing smooth circulation throughout the building. The main staircase is placed near the center of the plan, a familiar design solution that helps distribute movement evenly in both directions. Meanwhile, the restroom area is grouped at one end of the building, which simplifies the organization of plumbing and ventilation systems.
• Moving up to the second floor, the building transitions into the primary working areas. The offices are divided into several medium-sized rooms suitable for small teams or administrative departments. The structural grid aligns neatly with the interior partitions, allowing the design to remain simple and practical. At the center, the staircase hall continues to function as the main vertical circulation core and acts as a small transition space before entering the offices.
• The third floor follows a similar layout logic but introduces spaces that can be used as meeting rooms or larger offices. Placing these functions on the upper level often creates a quieter environment, which is more suitable for meetings or focused work.

From the exterior perspective, the building design is intentionally modest. A rhythm of columns runs across the façade, giving the structure a sense of order and proportion. The ground floor features arched openings that help soften the visual mass of the building and create shaded areas along the frontage. The pitched roof, likely covered with metal sheets or tile-like materials, gives the building a familiar and practical appearance suitable for regions with frequent rainfall.

The sectional drawings show a straightforward structural system consisting of reinforced concrete columns, beams, and cast-in-place slabs. The staircase core runs vertically through all levels, providing a clear and efficient circulation route.

Overall, this drawing set does not aim for complex architectural expression. Instead, it focuses on clarity, practicality, and functional organization. For architects, students, or designers looking for references on small administrative or office buildings, this project offers a clear and easy-to-understand example.
