1000sqm Prefabricated Steel Warehouse with Partial Two-Story Office

Prefabricated steel structure warehouse with partial two-story office building area 1000sqm, size 50*20*7m（Length *Width*Height）.This design of a steel structure warehouse with partial two-story offices not only meets the dual needs of warehousing and office, but also improves the overall operational efficiency through carefully designed spatial relationships.

1. Main Structural Design Points
The main body of the warehouse adopts a single-layer large-span prefabricated steel frame (portal frame or truss structure), and the local office area is a two-layer steel frame + composite floor.

The building adopts Q355B, the main beam/column adopts H-shaped steel, and the floor is a composite floor of corrugated steel plate-concrete.

2. Functional Zoning and Layout
The local two-story office of the steel structure warehouse realizes the natural separation of warehouse and office:
The first floor is usually designed as the warehouse operation area, loading and unloading area and some auxiliary office areas (display area, reception area, etc.)
The second floor is centrally set up with administrative functions such as management office and conference room

The prefabricated steel warehouse with partial two-story office combines storage and office functions and has the following significant advantages:
1. Maximize Space Utilization
Vertical expansion: Taking advantage of the high clearance of the warehouse, the office area can be increased without increasing the floor area through partial double-layer design, which is especially suitable for areas with high land costs.
Clear functional division: The first floor has a large span for storage/production functions, and the second floor is used as an office area to avoid the waste of land for building a separate office building.

2. Significant Cost-Effectiveness
Material and construction savings: The steel structure has a light weight and fast construction speed. The partial double-layer design saves more material and labor costs than building a separate office building.
Reduced foundation cost: Shared warehouse foundation reduces the foundation investment of independent office buildings.
Low maintenance cost: The steel structure is corrosion-resistant (galvanized or painted) and earthquake-resistant, and the long-term maintenance cost is lower than that of traditional structures.

3. Superior Structural Performance
High strength and flexibility: Steel structure can achieve large span design (such as 30-50 meters), and the first-floor warehouse does not need internal columns, which is convenient for shelf layout and logistics operations; the large span capacity of steel structure supports large space office layout (such as open office).
Strong load-bearing capacity of the local second floor: The steel frame can easily support the load of the second floor office, and can be pre-designed to adapt to future adjustments (such as adding or reducing offices).
Seismic durability: The toughness of steel is suitable for earthquake-prone areas, and anti-corrosion and fire-proof treatment can extend the service life.

4. Improved Operational Efficiency
Management Convenience: The office area overlooks the warehouse, monitors logistics or production processes in real time, and improves response speed.
Optimized employee movement lines: The warehouse and office area are directly connected by stairs/elevators to reduce cross-interference between people and goods and improve safety. 

5. Sustainability and Environmental Protection
Energy-saving potential: The office can be independently designed for lighting and ventilation (such as skylights and glass curtain walls) to reduce lighting energy consumption; the steel structure is recyclable and meets green building standards.
Thermal environment control: The partial double-layer design allows the use of differentiated temperature control systems for the office area and the storage area (such as separate air conditioning in the office) to reduce energy waste.

6. Design Flexibility and Scalability
Modular construction: Steel structures are easy to prefabricate and assemble, and the office area can be quickly expanded or the floor height can be adjusted in the future.
Adaptive transformation: If the storage needs change, the office space can be changed to other uses (such as display areas, laboratories).

7. Safety and Compliance Advantages
Clear fire protection zones: Through the design of fireproof partitions, evacuation stairs, etc., the fire protection regulations for offices and warehouses are met.
Noise isolation: Steel structures combined with sound insulation materials (such as rock wool sandwich panels) can effectively reduce the impact of noise from the lower warehouse on the office.

Steel Structure Warehouse with Partial Two-story Office Application
Small and medium-sized enterprises: owners who need to closely manage warehousing and administration.
E-commerce/logistics center: office area is used for order processing, customer service, etc.
Industrial plant: production monitoring and administrative office are combined.

Notes
Load calculation: it is necessary to ensure that the load-bearing capacity of the warehouse floor is suitable for office use (such as live load difference).
Code compliance: meet the requirements of local building regulations on floor height, evacuation, and fire zoning.
Comfort design: improve the quality of the office environment through insulation and sound insulation measures.

In the field of modern industrial buildings, steel structure warehouses are widely popular due to their advantages such as fast construction, controllable costs and high space utilization. Integrating office areas into warehouse design, especially adopting a partial two-story office layout, has become a major trend in current industrial building design.
