- Quick on-site assembly
- Consistent quality
- Weather-independent production
Panelized Systems
Wall and roof panels:
How it works:
- Panels manufactured in factory
- Walls, floors, roof components
- Assembled on-site
- More site work than modular
Characteristics:
- 50-70% factory completion
- More flexible than modular

- Traditional construction methods
- Most site work of all types
Characteristics:
- Lowest factory completion
- Most flexible
- Skill dependent assembly
- Material cost savings
Bulgarian Prefab Market

| Per m² | €900 |
Prefab panelized (80m²):
| Item | Cost |
|---|---|
| Foundation | €8,000 |
| Prefab kit | €45,000 |
| Delivery | €3,000 |
| Assembly | €8,000 |
| MEP | €8,000 |
| Finishing | €10,000 |
| Total | €82,000 |
| Per m² | €1,025 |
Imported modular (80m²):
| Item | Cost |
|---|---|
| Foundation | €8,000 |
| Modular units | €55,000 |
| Transport/crane | €8,000 |
| Site connections | €5,000 |
| Finishing | €6,000 |
| Total | €82,000 |
| Per m² | €1,025 |
Cost Analysis
Key findings:
- Prefab often costs 10-20% more in Bulgaria
- Traditional building is well-established, competitive
- Prefab savings depend on labor costs
- Import transport adds significant cost
- Foundation costs similar regardless
Timeline Comparison
Traditional Building
Standard timeline (80m²):
| Phase | Duration |
|---|---|
| Foundation | 2-4 weeks |
| Structure | 6-10 weeks |
| Roof | 2-3 weeks |
| MEP rough-in | 3-4 weeks |
| Interior | 8-12 weeks |
| Total | 6-8 months |
Prefab Building
Prefab timeline (80m²):
| Phase | Duration |
|---|---|
| Factory production | 4-8 weeks |
| Foundation (concurrent) | 2-4 weeks |
| Delivery and assembly | 1-2 weeks |
| Connections and finishing | 4-6 weeks |
| Total | 3-5 months |
Timeline Analysis
Prefab offers:
- 30-50% time reduction
- Less weather dependency
- More predictable schedule
- Faster move-in possible
But consider:
- Factory lead times vary
- Delivery scheduling critical
- Site must be ready
- Less flexibility for changes
Quality Considerations
Factory Quality Advantages
Controlled environment benefits:
Consistency:
- Climate-controlled production
- Jig-built precision
- Quality control processes
- Material storage proper
Efficiency:
- Less material waste
- Optimized production
- Skilled workers
- Repeatable processes
Quality Concerns
Potential issues:
Transport damage:
- Modules stressed in transit
- Connection points vulnerable
- Inspection before acceptance critical
Site connections:
- Junction quality critical
- Waterproofing at connections
- Thermal bridging possible
- Skilled installation needed
Foundation matching:
- Precision required
- Tolerance for errors low
- Survey accuracy essential
Suitability Assessment
When Prefab Makes Sense
Consider prefab when:
- Time is critical priority
- Remote site with labor challenges
- Consistent quality important
- Multiple similar units needed
- Energy efficiency priority (SIP)
- Weather conditions challenging
When Traditional is Better
Choose traditional when:
- Budget is primary concern
- Local labor is competitive
- Site access is restricted
- Custom design needed
- Expandability planned
- Resale perception matters
Bulgarian Context
For most Bulgarian projects:
- Traditional construction remains competitive
- Labor costs favor traditional
- Material availability good
- Prefab premium often not justified
- Under-100m² self-build works well traditionally

Frequently Asked Questions
Is prefab cheaper in Bulgaria?
Generally no. Traditional construction in Bulgaria is competitive, and prefab often costs 10-20% more due to limited local manufacturing and import costs. The cost equation may change as the market develops.
How fast can a prefab home be built?
From order to move-in: 3-5 months typically. Factory production takes 4-8 weeks, then 1-2 weeks for assembly, plus finishing. Compare to 6-8 months for traditional construction.
Are prefab homes lower quality?
No. Factory conditions often produce better quality than site building. However, quality depends on manufacturer reputation and installation expertise. Research your specific supplier carefully.
Can I get a mortgage for a prefab home?
Banks are increasingly accepting prefab homes. However, you may face more questions or requirements than for traditional construction. Check with lenders before committing.
Do prefab homes hold their value?
In Western markets, quality prefab resells well. Bulgarian market perception is still developing. High-quality prefab should retain value; lesser-known systems may face skepticism.
Make an Informed Choice
Prefab offers genuine advantages in some situations, but traditional construction remains the practical choice for most Bulgarian home projects. Evaluate your specific priorities—time, cost, quality, flexibility—before deciding.
