Frequently Asked Questions
Should I use Ytong (aerated concrete) blocks?
Ytong and similar aerated concrete blocks offer good insulation and easy cutting/working. They work well for external walls combined with external insulation. They require specific mortars and techniques, so ensure your builder is familiar with them.
What’s better for roofing: tiles or metal?
Both work well in Bulgaria. Tiles offer traditional aesthetics and proven longevity. Metal is lighter, faster to install, and can be more budget-friendly. For mountain areas with heavy snow, standing seam metal handles snow shedding well.
How much insulation do I need?
For Bulgarian climate, aim for minimum 12-15cm external wall insulation in lowlands, 15-20cm in mountains. Roof insulation should be 20-25cm minimum. More insulation costs more upfront but pays back through lower heating bills.
Can I use local/traditional materials?
Yes, and they often work excellently. Local stone for foundations, timber from Bulgarian forests, and traditional techniques can create beautiful, durable homes. Our plans accommodate various material choices.
Material Budgeting
For a typical 80-100m² house, expect material costs of:
| Category | Budget Range |
|---|---|
| Foundation materials | €3,000-5,000 |
| Wall materials | €5,000-8,000 |
| Roof materials | €4,000-7,000 |
| Windows/doors | €3,000-6,000 |
| Insulation | €2,000-4,000 |
| Interior finishing | €5,000-10,000 |
