Cost of SIP panels

The SIP panels themselves are the primary material cost in constructing a SIP house. The price of SIP panels varies based on several factors:

  • Material type. SIP panels typically use expanded polystyrene (EPS), polyurethane, or polyisocyanurate for the insulating core. EPS is the most common and cost-effective, while polyurethane and polyisocyanurate provide higher insulation values at a higher cost.
  • Panel thickness. Thicker panels offer better insulation but are more expensive. Typical thicknesses range from 100 mm to 300 mm.

For an 80 m² house, assuming an average price of 50 € – 100 € per square meter, the cost for SIP panels would be:

  • Lower range – 80m² x 50 €/m² = 4,000 €.
  • Upper range – 80m² x 100 €/m² = 8,000 €.

Design and engineering fees

Custom-designed SIP houses require architectural and engineering services to ensure structural integrity and compliance with European building codes. These fees typically include:

  • Architectural Design. Depending on the complexity, fees can range from 1,500 € to 5,000 €.
  • Engineering Services. Structural engineering services, necessary for ensuring safety and compliance, typically cost between 1,000 € and 3,000 €.

SIP house pricing – Foundation cost

The type of foundation required for an 80 m² SIP house will affect the overall cost. Common foundation types include slab-on-grade, crawl spaces, and basements.

  • Slab-on-grade. This is often the most cost-effective option, with prices ranging from 5,000 € to 8,000 €.
  • Crawl space. Adds to the cost, typically ranging from 6,000 € to 10,000 €.
  • Basement. The most expensive option, with costs ranging from 10,000 € to 20,000 € or more.

Construction labor

Labor costs for assembling SIP panels and completing the construction of a SIP house are a significant part of the budget. Labor costs can vary based on location, the complexity of the build, and the experience of the construction crew.

  • Assembly of SIP Panels. This typically costs between 20 € to 40 € per square meter. For an 80 m² house, this would be:
    • Lower range – 80 m² x 20 €/m² = 1,600 €.
    • Upper range – 80 m² x 40 €/m² = 3,200 €.
  • General construction labor. Additional labor costs for tasks such as plumbing, electrical work, HVAC installation, and finishing work generally range from 1,000 € to 1,500 € per square meter. For an 80m² house:
    • Lower range – 80 m² x 1,000 €/m² = 80,000 €.
    • Upper range – 80 m² x 1,500 €/m² = 120,000 €.

Utility connections and systems

Connecting the house to utilities like water, electricity, and sewage involves additional costs.

  • Electrical and plumbing. Integrating these systems into the SIP structure can cost between 4,000 € and 8,000 €.
  • HVAC systems. Proper heating, ventilation, and air conditioning systems are essential. These can cost between 3,000 € and 6,000 €.

Interior finishes

The cost of interior finishes can vary widely based on the homeowner’s preferences and the quality of materials chosen. This includes:

  • Flooring. Options range from affordable laminates (10 € to 20 € per square meter) to more expensive hardwood or tile (20 € to 50 € per square meter). For an 80 m² house:
    • Lower range – 80 m² x 10 €/m² = 800 €.
    • Upper range – 80 m² x 50 €/m² = 4,000 €.
  • Walls and ceilings. Drywall installation and painting typically cost between 10 € and 20 € per square meter. For 80 m²:
    • Lower range – 80 m² x 10 €/m² = 800 €.
    • Upper range – 80 m² x 20 €/m² = 1,600 €.
  • Cabinetry and fixtures. Kitchen and bathroom cabinets, along with fixtures, can range from 5,000 € to 15,000 €.

SIP house pricing – Exterior finishes

Exterior finishing includes siding, roofing, windows, and doors. The choice of materials and the complexity of the design can significantly impact costs.

  • Siding: Options include vinyl, wood, fiber cement, or brick, with costs ranging from €10 to €30 per square meter. For an 80m² house:
    • Lower Range – 80 m² x 10 €/m² = €800 €.
    • Upper Range – 80 m² x 30 €/m² = 2,400 €.
  • Roofing. The cost of roofing materials (asphalt shingles, metal, tile) and installation ranges from 4,000 € to 10,000 €.
  • Windows and Doors. High-quality, energy-efficient windows and doors can add 3,000 € to 8,000 € to the budget.

Permits and inspections

Building permits and inspections are necessary to ensure the construction complies with local building codes and standards. These costs vary by location.

  • Building Permits. Fees can range from 500 € to 2,000 €, depending on the local jurisdiction and the size of the project.
  • Inspections. Multiple inspections are required at different stages of construction, costing between 1,000 € and 2,000 € in total.

SIP house pricing – Miscellaneous cost

Several additional costs can arise during the construction of a SIP house, including:

  • Site Preparation. Clearing and grading the site, which can cost between 1,000 € and 3,000 €.
  • Landscaping. Basic landscaping can add another 2,000 € to 5,000 € to the total cost.
  • Contingency Fund. It’s wise to set aside 10-20% of the total project cost for unexpected expenses.
