What to Ask Before Buying Prefab Homes from China?

Buying prefab homes from China can be a smart choice for developers, contractors, distributors, resort owners, and project buyers.

But before you place an order, do not only ask:

“How much is it per square meter?”

That is not enough.

A prefab home is not just a product. It is a building system. It involves structure, materials, factory production, packing, shipping, local installation, and long-term use.

The right questions can help you avoid wrong suppliers, hidden costs, installation problems, and project delays.

Here are the most important questions to ask before buying prefab homes from China.

1. What Type of Prefab Home System Do You Offer?

Not all prefab homes are the same.

Some are light steel homes. Some are container houses. Some are temporary modular units. Some are precast concrete prefab homes.

Before comparing prices, ask the supplier:

• What is the main structure?
• Is it light steel, container, timber, or precast concrete?
• Is it suitable for long-term residential use?
• Is it suitable for villas, resorts, rural housing, or development projects?
• Can the system meet local project requirements?

For project buyers, the building system is more important than the appearance.

SY home focuses on precast concrete prefab homes with a dry-connection structure system. The system is designed for practical, solid, and beautiful modern buildings through modular assembly building technology.

2. What Structural Technology Is Used?

This is one of the most important questions.

Do not only look at the house rendering. Ask the supplier how the building is actually supported and connected.

You can ask:

• How are the columns and beams connected?
• Is the structure mainly built on site or produced in the factory?
• Does the system use wet construction or dry connection?
• Is the structure suitable for repeated project delivery?
• Can the supplier show structure drawings or real project photos?

SY home uses a patented dry-connection precast concrete structure system. The system reduces heavy wet work on site and makes the installation process clearer and easier to manage.

Question	Why It Matters
What is the main structure?	It affects strength, durability, and local approval.
Is dry connection used?	It can reduce wet work, waiting time, and site uncertainty.
Are the components factory-made?	It helps improve quality control and repeatability.
Can the structure support different designs?	It affects villas, resorts, ADU, and custom projects.
Are drawings available?	It helps your engineer or local builder review the system.

Dry connection, mixed structure, standard component production, finished product delivery, and controllable cost are the key parts of the building system.

3. What Materials Are Included in the Quotation?

Many prefab home quotations look attractive at first.

But the problem is that different suppliers include different things.

Before comparing prices, ask what is included:

• Main structure
• Wall panels
• Roof system
• Floor system
• Windows and doors
• Exterior finish
• Interior wall finish
• Bathroom
• Kitchen
• Electrical system
• Plumbing system
• Fasteners and connectors
• Packing
• Shipping
• Installation guide

A low price may only include the basic shell. After you add the missing parts, the final cost may become much higher.

For a real project, you need a clear quotation, not just a low number.

4. Can You Provide Real Project Cases?

A serious prefab home supplier should be able to show real projects.

Ask for:

• Project photos
• Structure photos
• Installation photos
• Floor plans
• Building area
• Material details
• Completion photos
• Project location
• Installation process

Do not rely only on 3D renderings.

For example, one project in SY home’s technical materials is a villa project in Bengbu, Anhui. The project has a total building area of 263 square meters, with two floors and a reinforced concrete frame structure.

The same project also uses ALC wall panels and insulated decorative exterior panels.

Real project details are important because they show whether the supplier can actually deliver what they promise.

5. What Factory Capacity Do You Have?

Prefab homes depend on factory production.

A supplier may have good salespeople, but that does not mean they have stable production ability.

Ask these questions:

• Do you have your own factory?
• What components can you produce?
• Do you have PC component production lines?
• Do you have mold systems?
• Do you have a steel reinforcement production line?
• Do you have a wall panel production line?
• How do you control quality before shipping?
• Can you handle bulk project orders?

For developers, contractors, and distributors, factory capacity affects delivery time, product consistency, and long-term cooperation.

If you plan to buy repeatedly, this question is even more important.

6. Can You Customize the Layout and Exterior Design?

Prefab does not mean every house must look the same.

For resorts, villas, rural homes, and overseas projects, buyers often need different layouts and exterior styles.

Ask the supplier:

• Can the floor plan be adjusted?
• Can the roof style be changed?
• Can window and door positions be changed?
• Can the exterior wall material be changed?
• Can the interior finish be upgraded?
• Can the design match local market preferences?
• Can the system support different building styles?

SY home’s frame structure allows flexible space planning. Its technical material notes that exterior wall options can include block, ALC, glass, and other materials, making the system suitable for different building styles.

This is important if you are building for a local market, resort brand, or real estate project.

7. How Much Work Is Needed on Site?

Prefab homes are not “zero work” buildings.

You still need foundation work, local labor, equipment, and installation management.

Before buying, ask:

• What work must be completed before delivery?
• What foundation is required?
• What equipment is needed on site?
• How many workers are needed?
• How long does installation usually take?
• Which parts require local finishing?
• Which parts are completed in the factory?
• Is wet work required on site?

SY home’s dry-connection system is designed to reduce heavy wet work and simplify on-site assembly. The project documents also show dry floor systems, integrated kitchen, and integrated bathroom using dry construction methods.

For overseas buyers, this can make the installation process easier for local teams to understand.

8. How Are the Homes Packed and Shipped?

Shipping is a big part of buying prefab homes from China.

Do not wait until the order is finished to discuss packing.

Ask early:

• Can the components fit into standard containers?
• How many containers are needed?
• How are the components protected?
• Are all parts numbered?
• Is there a packing list?
• Is there a loading plan?
• Can the supplier provide export documents?
• Can they help estimate freight volume?

Good packing is not just about saving space. It also helps the local installation team find the right parts quickly.

For project buyers, clear packing and labeling can save time and reduce mistakes on site.

9. What Installation Support Do You Provide?

This is a key question.

A prefab home supplier should not only sell products. They should support installation.

Ask:

• Do you provide installation drawings?
• Do you provide an installation manual?
• Do you provide videos or SOP documents?
• Can you provide online installation guidance?
• Can you train local workers?
• Can you send engineers to the site if needed?
• How do you handle installation questions after delivery?

For overseas projects, this support can make a big difference.

A supplier who understands project delivery will prepare clear drawings, component numbers, installation steps, and communication support.

10. What Documents Can You Provide for Project Buyers?

For B2B buyers, documents are part of the product.

Ask whether the supplier can provide:

• Product catalog
• Technical drawings
• Material list
• BOQ
• Packing list
• Installation guide
• Project proposal
• Factory photos
• Certificate documents
• Patent or technical background materials
• Case study documents

These documents help your team, local contractor, investor, or project owner make decisions.

They also make your communication more professional.

11. What Is the Real Delivery Timeline?

Do not only ask for production time.

Ask for the full timeline:

• Design confirmation time
• Drawing review time
• Deposit and contract process
• Production time
• Quality inspection time
• Packing time
• Inland transport time
• Sea freight time
• Customs clearance time
• Local installation time

A professional supplier should help you understand the full process, not only the factory production schedule.

This is especially important for resort openings, real estate projects, and government or commercial projects with fixed deadlines.

12. What Quality Control Steps Do You Follow?

Prefab homes must be checked before they leave the factory.

Ask:

• How do you inspect raw materials?
• How do you inspect concrete components?
• How do you check component size?
• How do you check connectors?
• How do you check wall panels?
• How do you check packing?
• Can you provide inspection photos before shipping?
• Can third-party inspection be arranged?

Quality control is easier when key parts are produced in the factory, but only if the supplier has a clear inspection process.

For bulk buyers, stable quality is more important than one good sample.

13. What Is Your Technical Background?

Prefab homes are not simple products.

The supplier should have technical knowledge in structure, production, installation, and project delivery.

Ask about:

• Engineering team
• Design support
• Structural experience
• Factory experience
• Expert cooperation
• Project references
• Patents or technical development
• Industry experience

SY home’s related technical background includes prefabricated building design, bidding, production, and construction experience. The technical advisor team is connected with Professor Guo Zhengxing’s team from Southeast University, with experience in structural and complex engineering research.

This kind of technical background gives project buyers more confidence.

14. What Should I Prepare Before Asking for a Quote?

To get a useful quotation, prepare more than a simple message.

Send the supplier:

• Project country
• Project location
• Building use
• Quantity
• Target building area
• Number of floors
• Floor plan or reference image
• Exterior style
• Interior finish level
• Local climate
• Foundation condition if available
• Target budget
• Expected delivery time

The more details you provide, the more practical the proposal will be.

A serious supplier should also ask you questions before quoting. If they give a price too quickly without understanding your project, be careful.

15. Red Flags to Watch Out For

Be careful if a supplier:

• Only talks about low price
• Cannot explain the structure
• Cannot show real project photos
• Only shows renderings
• Gives unclear quotations
• Avoids technical questions
• Cannot provide drawings
• Has no installation support
• Cannot explain packing and shipping
• Promises everything without checking your project details

Buying prefab homes is not only about finding the cheapest supplier.

It is about choosing a partner who can help you finish the project smoothly.
