How Much Does a Prefab House Cost in Bulgaria? Price Breakdown
Understanding the true cost of a prefab house in Bulgaria requires looking beyond advertised prices. This breakdown covers every expense category so you can budget accurately for your project.
Factory House Prices
Bulgarian prefab manufacturers quote prices at various specification levels. Current 2025 market rates:
Basic specification (450-600 EUR/m²) includes timber frame structure, standard insulation (15cm mineral wool), basic windows (double-glazed PVC), electrical wiring without fixtures, plumbing rough-in, and basic interior finishing (painted walls, laminate flooring).
Standard specification (600-850 EUR/m²) upgrades to enhanced insulation (20cm), better windows (triple-glazed with improved U-values), complete electrical installation with basic fixtures, full plumbing with standard sanitary ware, and improved finishes (quality flooring, tiled bathrooms).
Premium specification (850-1,200 EUR/m²) features superior insulation systems, high-performance windows, smart home wiring, premium sanitary ware and fixtures, and designer finishes throughout.
For a 100m² home, factory prices range from 45,000 EUR (basic) to 120,000 EUR (premium).
Foundation Costs
Foundation expenses depend on ground conditions and foundation type:
Strip foundations: 60-90 EUR/m² of building footprint. Suitable for stable ground with good bearing capacity. A 100m² house requires approximately 6,000-9,000 EUR.
Raft/slab foundations: 80-120 EUR/m² of building footprint. Necessary for weaker ground or where basement waterproofing is required. Budget 8,000-12,000 EUR for 100m².
Piled foundations: 120-180 EUR/m². Required for unstable ground, high water tables, or sloped sites. Costs 12,000-18,000 EUR for 100m².
Soil investigation (400-800 EUR) determines which foundation type your site requires. Never skip this step.
Site Preparation Expenses
Land clearing and leveling: 500-3,000 EUR depending on vegetation, slopes, and debris removal requirements.
Access road improvements: 1,000-5,000 EUR if delivery trucks and cranes cannot reach your site on existing roads.
Temporary facilities: 500-1,500 EUR for construction water and electricity connections.
Crane hire: 800-2,000 EUR for module placement, typically included in assembly costs but verify with your manufacturer.
Permit and Professional Fees
Bulgarian construction requires proper documentation regardless of building method:
Architectural project: 1,500-4,000 EUR depending on complexity. This covers design, technical drawings, and permit documentation. Our architecture services provide complete permit-ready projects.
Structural engineering: 500-1,500 EUR for foundation design and structural calculations.
Building permit fees: Municipal fees vary, typically 500-2,000 EUR based on building size and location.
Technical supervision: 1,000-2,500 EUR for mandatory construction oversight by a licensed supervisor.
Geodesy services: 400-800 EUR for site survey and building stakeout.
Total professional fees: approximately 4,000-10,000 EUR.
Utility Connection Costs
Electricity connection: 500-2,000 EUR depending on distance from the grid and required capacity.
Water connection: 500-1,500 EUR plus any pipeline extension costs.
Sewage connection: 800-2,500 EUR for municipal sewer, or 3,000-6,000 EUR for septic system installation.
Gas connection (if available): 1,000-3,000 EUR.
Remote locations significantly increase utility costs. Verify connection availability and costs before purchasing land.
Hidden and Overlooked Costs
VAT: Most quoted prices exclude 20% VAT. Verify whether quotes include or exclude tax.
Transport: Factory-to-site transport costs 1,500-4,000 EUR depending on distance and access difficulty.
Interior modifications: Factory plans rarely match exact requirements. Budget 2,000-5,000 EUR for customization requests.
External works: Driveways, paths, fencing, and landscaping add 3,000-15,000 EUR depending on scope.
Furnishings and appliances: Often forgotten in budgeting. Basic furnishing costs 5,000-15,000 EUR.

Add 20% VAT where applicable and 10% contingency for unexpected expenses. Realistic total budget: approximately 110,000-120,000 EUR.
Cost Comparison with Traditional Construction
Traditional construction for equivalent specification costs 85,000-110,000 EUR for the building alone, plus similar foundation, permit, and utility costs. Total traditional build: 130,000-150,000 EUR.
Prefab savings of 15-25% remain after accounting for all expenses. Compare construction methods in detail.
