The single-slope prefabricated house is becoming popular due to its simplicity, cost-effectiveness, and quick installation. With a lightweight yet sturdy design, this house meets all basic functionality while ensuring comfort and aesthetic appeal. Let's explore with BMB Steel the 10 most outstanding single-slope prefab house designs today, with construction costs suitable for living and business needs.

1. What is a single-slope prefabricated house?

A single-slope prefabricated house is a steel frame with a single roof that slopes in one direction. This style has a simple design, without complex features. Single-slope prefab homes are constructed in three stages: design, fabrication and installation. This type of house is similar to a traditional one-story house but uses a sturdy steel frame.

2. Characteristics of single-slope prefabricated houses

2.1. Structure of single-slope prefabricated houses

Single-slope prefab homes are designed to be simple, durable, and flexible. The main components of a single-slope prefabricated house include:

• Foundation: The foundation of a single-slope prefabricated house is typically made of reinforced concrete, providing good load-bearing capacity. This allows the structure to withstand weather impacts such as storms, tornadoes.
• Frame: The frame consists of columns and beams connected by bolted connections. The use of a single-slope frame structure helps to reduce the number of connections and simplify the construction and installation process.
• Roof: The roof is designed with a suitable slope to allow for quick water drainage, preventing water from pooling and damaging the roof.
• Walls and partitions: Single-slope prefab houses often use lightweight materials like tempered glass, wood, and panels for walls and partitions, making construction easier and ensuring aesthetics.

2.2. Specifications of single-slope prefabricated houses

The design of a single-slope prefabricated house needs to meet specific technical specifications to ensure safety and stability for the home. The basic specifications of a single-slope prefabricated house include:

• Width of the house: The width is measured from the outer edge of the first wall to the outer edge of the opposite wall.
• Length of the house: The length is measured from the outer edge of the front wall to the outer edge of the back wall from the direction of the main entrance.
• Height of the house: The height is measured from the base of the column to the intersection point of the roof and the wall.
• Roof slope: The slope of the roof for a single-slope prefabricated house is typically calculated with a gradient of i = 15% to ensure that rainwater drains quickly, preventing water accumulation on the roof that could cause damage and increase the lifespan of the roofing material.
• Column spacing: Column spacing is the distance between the columns along the length of the house and is determined based on the height of the structure.
• Load capacity: To ensure safety, load-bearing capability, the design and construction of a single-slope prefabricated house must carefully calculate the load, including self-weight, live load, wind load, special loads such as crane loads (if applicable).

3. Advantages and disadvantages of single-slope prefabricated houses

3.1. Advantages of single-slope prefabricated houses

• Cost-saving: Prefabricated houses use steel frames, significantly reducing costs compared to traditional reinforced concrete construction, making them suitable for projects with a low budget.
• Quick construction: The process from planning to handover can take only 6-7 weeks, much faster than traditional constructions, allowing homeowners to quickly enjoy their living space.
• Easy installation and maintenance: With lightweight materials that are easy to assemble, single-slope prefabricated houses can be easily transported and installed. Additionally, these materials are easy to replace or renovate in case of damage, simplifying maintenance.
• Optimized usable space: Single-slope prefabricated houses can be built on limited areas while still ensuring all necessary functions, making them suitable for families looking to optimize their living space.

3.2. Disadvantages of single-slope prefabricated houses

• Prone to corrosion: Steel frames can corrode when exposed to the environment, requiring good protection and surface treatment to avoid reducing their lifespan.
• Poor heat resistance: Steel loses its load-bearing capacity when temperatures reach 500-600°C, making prefabricated houses unsuitable for high-temperature or fire-prone environments.
• Regular maintenance required: Prefabricated houses need regular maintenance to maintain durability, especially the steel frame, leading to significant annual maintenance costs.
