Custom Prefabricated One-and-a-Half-Story House
A custom prefabricated one-and-a-half-story house is a building form that combines practicality and economy, suitable for families with limited budgets or small homestead areas, especially for rural self-built housing scenarios.

1. Design Features
A one-and-a-half-story house typically consists of a complete living space on the first floor and a half-story loft. The loft can be accessed via stairs or a ladder and offers flexible functionality. It can serve as a storage room or be transformed into a temporary guest room, study, or leisure area. The exterior style is diverse, covering modern simplicity, European classicism, rural charm, and more. Color schemes and decorative elements (such as window frames and roof shapes) can be customized according to needs. Some designs incorporate terraces, double entry doors, or open layouts, enhancing both lighting and ventilation while strengthening spatial interaction. For example, adding dormer windows to the roof can increase loft lighting and create a unique visual highlight.
2. Functional Layout
The first floor is usually planned as a basic living area, including a living room, dining room, kitchen, 2-3 bedrooms, and a bathroom to meet daily living needs. The loft's function varies based on family requirements: if additional living space is needed, it can be designed as a bedroom or study; if storage is a priority, shelves or enclosed storage rooms can be added. Some units feature an external terrace or observation deck attached to the loft, expanding outdoor activity space. Additionally, custom services support flexible adjustments to the internal layout, such as modifying the number of bedrooms based on family structure, enlarging the kitchen area, or even adding special functional areas like a mahjong room.
3. Economic and Applicability Advantages
Compared to a two-story house, a one-and-a-half-story design can save approximately 100,000 yuan in construction costs, mainly due to reduced building material usage and a shorter construction period (typically saving 20%-30% of time). Its footprint is mostly between 100-150 square meters, suitable for families with limited homestead areas. From an applicability perspective, such houses can meet both elderly care and self-living needs while incorporating designs like courtyards and terraces that align with leisure lifestyle preferences, making them particularly popular among rural self-built housing groups.
4. Custom Services and Case References
Custom services typically offer one-on-one design, adjusting drawings based on homestead dimensions and family needs. Some companies (such as Drawing House) also provide ready-made drawings in various styles and sizes for selection. For example, one case covers an area of 13.8m × 9.9m with a building area of 134 square meters, including a rooftop drying area; another case spans 13.80m × 11.30m, featuring a master bedroom and study in the loft to accommodate both living and office needs. For further customization, specific processes can be inquired about through the design company's official website or channels like WeChat.
