Analysis of Client Needs and Preliminary Scheme Selection
Ivan’s backyard space was limited, and he hoped to minimize damage to the garden greenery and avoid the long construction period. His core demands included:
- Rapid deployment: He expected to complete the whole process from purchase to move-in within 2 months.
- Space flexibility: He needed a functional space including 2 bedrooms, 1 living room, and a full set of kitchen and bathroom facilities.
- Minimized on-site interference: The installation process was required to be simple and clean, without the need for large construction machinery.
After comparing traditional brick-concrete buildings, wooden cabins, and various modular buildings, Ivan found that the YG expanding container house fully met his expectations. This type of house is in a compact state during transportation, which greatly reduces the cost and difficulty of international sea freight. After being delivered to the backyard, it can be quickly expanded to form a complete living space.
Why Choose Prefab Expandable House Finally?
Among numerous options, Ivan settled on the prefab expandable house mainly based on the following key advantages:
- Unmatched transportation and installation efficiency: Take the 30FT model he finally selected as an example. The folded transportation dimension is only W2200L9000H2480mm, which can easily pass through community roads and enter the backyard. The usable internal area after expansion reaches about 53.7 square meters (W6200*L8660mm), perfectly resolving the contradiction between transportation restrictions and space requirements.
- High customization to meet personal needs: After communicating with us, Ivan learned that everything could be customized. He did not need to compromise on fixed house types. We could design an exclusive layout plan of 2 bedrooms, 1 living room, 1 kitchen and 1 bathroom according to the size of his backyard and his functional ideas.
- Complete delivery and reliable quality: The house will be equipped with all doors and windows, kitchen cabinets, bathroom fixtures, as well as water and electricity systems, truly realizing “move-in ready”. The main structure adopts Q235 steel strip frame and EPS sandwich panel walls, ensuring thermal insulation and structural safety under Bulgaria’s climate conditions.

Tailor-Made Design Process
Our team conducted in-depth communication with Ivan for many times to create this prefab shipping container tailored for his backyard:
- Layout planning: We provided several proven 2-bedroom layout cases for reference. Finally, we determined an optimized scheme where the two bedrooms are placed at both ends to ensure privacy, and the living room is connected with the kitchen to enhance the sense of space.
- Interior upgrade: According to Ivan’s suggestions, the floor was upgraded to easy-to-clean ceramic tiles, and the kitchen cabinets adopted a U-shaped design with wall cabinets to maximize the kitchen storage space. The bathroom is equipped with high-quality washbasins, toilets and independent shower rooms.
- Exterior and performance optimization: Considering the winter in Sofia, we recommended upgrading the external wall panels to 100mm thick polyurethane (PU) panels, which significantly improves thermal insulation performance. Meanwhile, we added an elegant sloped roof and several broken-bridge aluminum floor-to-ceiling windows to the house to increase lighting and better integrate with the garden landscape.
Delivery Process of Prefab Expandable House
The entire delivery process was clear and efficient:
- Production and quality inspection: All components were prefabricated, assembled and tested in the factory, and then compressed into a folded state.
- Sea freight to Bulgaria: The folded house was shipped as a standard freight unit from Chinese ports to Burgas Port in Bulgaria. After customs clearance, it was delivered to the doorstep by a local transportation company.
- Rapid expansion in the backyard: Our technical team guided local assistants through remote video, and only took two days to complete the positioning, expansion, structural locking and final connection of water and electricity systems of the house.
