Lifting a house to create additional living space beneath is a common practice in New Zealand, particularly in areas prone to flooding or where land use is maximized due to increasing urban density. This article provides a comprehensive overview of the costs associated with lifting a house and building underneath, considering various factors such as location, house type, foundation requirements, and additional construction costs. We will delve into the intricacies of the process, offering insights into the financial implications and potential benefits.

1. Understanding the Concept of Lifting a House

Lifting a house involves raising the structure off its foundation to create space for a new level below. This process can be motivated by several factors:

  • Flood Mitigation: In areas susceptible to flooding, raising homes can protect properties from water damage.
  • Increased Living Space: Homeowners often seek to expand their living areas by adding rooms, garages, or storage beneath their houses.
  • Compliance with Building Codes: Some local regulations require homes to meet specific height requirements, especially in flood-prone zones.

2. Key Factors Influencing Cost

The cost of lifting a house and building underneath varies significantly based on several factors:

2.1. Location

Geographical location plays a crucial role in determining costs. Urban areas, particularly in cities like Auckland and Wellington, tend to have higher construction and labor costs compared to rural regions.

2.2. Type of House

The structure of the house also affects the price. Different building materials (timber, brick, etc.) and architectural styles may require specialized lifting techniques and additional safety measures.

2.3. Foundation Type

Houses with different foundation types (concrete slab, piers, etc.) may incur varying costs. For instance, homes on concrete slabs often require more extensive lifting equipment and procedures than those on piers.

2.4. Local Regulations and Permits

Obtaining the necessary building permits and adhering to local regulations can add to the overall cost. Homeowners should consult with local councils to understand zoning laws and the required permits.

3. Breakdown of Costs

To provide a clearer picture, we can break down the costs associated with lifting a house and building underneath into several categories:

3.1. Lifting Costs

The cost to lift a house generally ranges from NZD 10,000 to NZD 30,000. The factors affecting this range include:

  • Size and weight of the house
  • Foundation type
  • Accessibility of the site
  • Timeframe for completion

3.2. Construction Costs for New Space

Once the house is lifted, the construction costs for the new space can vary widely depending on the intended use of the area:

  • Basic Storage Area: NZD 20,000 ー NZD 50,000
  • Finished Living Space: NZD 50,000 ー NZD 150,000
  • Garage or Workshop: NZD 30,000 ー NZD 100,000

3.3. Additional Costs

There are additional costs to consider, which may include:

  • Utility reconnections (water, electricity, sewage)
  • Landscaping after construction
  • Insurance adjustments
  • Consultation and legal fees related to permits

4. Steps Involved in Lifting a House

The process of lifting a house and building underneath involves several steps:

4.1. Planning and Consultation

Consulting with architects, builders, and local councils is essential for effective planning. This stage involves assessing the feasibility and determining the costs of lifting the house.

4.2. Obtaining Permits

Before any work begins, homeowners must apply for the necessary permits from local authorities. This step ensures that the project complies with local building codes and regulations.

4.3. Preparing the Site

The site must be prepared for lifting, which may involve clearing the area and ensuring access for heavy machinery.

4.4. Lifting the House

Specialized equipment, such as hydraulic jacks, is used to lift the house carefully. This process requires skilled labor to ensure safety and precision.

4.5. Building Underneath

Once the house is lifted, construction of the new space can proceed. This includes framing, electrical work, plumbing, and finishing.

4.6. Final Inspections

After the construction is complete, final inspections by local authorities will ensure everything meets safety standards.

5. Financing Options

Homeowners may explore various financing options to cover the costs associated with lifting a house and building underneath:
