Layout Design of Prefabricated Houses with Three Bedrooms and One Living Room

The layout design of prefabricated houses with three bedrooms and one living room should incorporate considerations for space utilization, functional zoning, and living requirements. Below are typical examples and design highlights:

1. Modern Single-Story Self-Built House (Approximately 90 Square Meters)
This design centers around an open layout. Upon entering, there is a large living room (approximately 25-30 square meters) connected to an outdoor corridor to enhance natural lighting and ventilation. Behind the living room is the dining area (approximately 12 square meters), which forms an 'L'-shaped flow with the large kitchen (approximately 8-10 square meters) on the west side, shortening the distance between meal preparation and dining. The three bedrooms are concentrated on the east side of the house, with the master bedroom (approximately 15 square meters) featuring an independent wardrobe, and the secondary bedroom (approximately 12 square meters) and children's room (approximately 10 square meters) sharing a corridor to minimize wasted space. This layout is suitable for a family of three, emphasizing interaction in public areas and privacy in personal spaces.

2. Simple European-Style Single-Story Bungalow (Approximately 113 Square Meters)
Based on the design principle of 'basic functionality + aging suitability,' the living room (approximately 20 square meters) and dining area (approximately 15 square meters) are integrated to create a spacious and airy activity area. The kitchen (approximately 10 square meters) features a U-shaped countertop to improve cooking efficiency. Among the three bedrooms, the master bedroom (approximately 18 square meters) has a reserved space for heating installation, while the secondary bedroom (approximately 14 square meters) and guest room (approximately 12 square meters) are located near the bathroom (approximately 5 square meters) for convenient nighttime use. This plan is suitable for elderly care or low-frequency social needs, with flexible heating options such as radiators or underfloor heating available in winter.

3. 73 Square Meter Compact Layout
Optimized for small apartments, this design includes a shoe-changing area (approximately 2 square meters) on the left upon entering and an integrated sideboard (approximately 1.5 meters long) on the right, forming a transitional area between the entrance and dining room. The living room (approximately 18 square meters) and dining area (approximately 10 square meters) extend visually through the use of soft-light tiles, and the walls are painted with white latex paint to enhance reflection. Among the three bedrooms, the master bedroom (approximately 15 square meters) is equipped with built-in wardrobes, the secondary bedroom (approximately 12 square meters) uses榻榻米 (tatami) bed storage, and the children's room (approximately 10 square meters) meets learning needs through customized desks and bookshelves. This design achieves high capacity in a small area through vertical space utilization and multi-functional furniture.

4. 64 Square Meter Ultra-Small Apartment Optimization
Practicality is enhanced through 'space reuse': the master bedroom (approximately 14 square meters) expands its resting area by removing non-load-bearing bay windows; the children's room (approximately 10 square meters) adopts integrated furniture combining a bed, desk, and bookshelf to reduce furniture footprint; the tatami room (approximately 8 square meters) features a hydraulic lifting table, serving as both a guest room and study. The dining area (approximately 6 square meters) selects an extendable dining table (expanding to 1.3 meters) paired with a finished cabinet (approximately 2 meters high) for tableware and miscellaneous item storage. This plan is suitable for singles or small families, emphasizing functional flexibility and storage efficiency.

Design Recommendations:

• For prefabricated house layouts, confirm the dimensions of modular components (such as wall thickness and door/window positions) in advance to avoid structural damage during later renovations.
• For rural self-built houses, refer to modern or simple European-style examples and prioritize planning for dynamic and static zoning (concentrated bedrooms and open public areas).
• For small apartments, enhance the sense of space through customized furniture, light-colored decor, and mirror decorations, avoiding complex partitions that compress the area.
