Renovating your home is an exciting way to improve functionality, add value, and create a space that better suits your lifestyle. But one of the first questions homeowners ask is: How much does a renovation cost?
At Pearson Built, we understand that every renovation is unique, and costs can vary significantly depending on the size and scope of the project. In this guide, we’ll break down key cost factors and give you an idea of what to expect when budgeting for your renovation in Christchurch.
Factors That Affect Renovation Costs
Several factors influence the cost of a renovation, including:
1. Scope of Work
• A small refresh (painting, flooring, minor updates) may cost anywhere from $5,000 to $30,000.
• A mid-range renovation (kitchen or bathroom upgrade, internal layout changes) typically falls between $30,000 and $150,000.
• A full home renovation or extension can range from $150,000 to $500,000+, depending on complexity.
2. Materials & Finishes
The type of materials you choose has a major impact on the final price. For example:
• Standard materials (laminate benchtops, budget-friendly cabinetry) will be more affordable.
• Premium finishes (stone benchtops, custom cabinetry, high-end flooring) will increase costs.
3. Structural Changes
Removing or altering load-bearing walls, adding extra rooms, or making major structural modifications requires engineering expertise and council approvals, which add to costs.
4. Labour & Project Management
Labour costs depend on the complexity of the work and the trades involved. At Pearson Built, we ensure that all work is carried out by skilled professionals, delivering high-quality results efficiently.
5. Council Consents & Compliance
If your renovation involves structural changes, plumbing, or electrical work, you may need council consent, which can add $5,000 to $15,000+ to your budget, depending on the project.
