Real Homes Extension Calculator

Extending your home is a significant investment that can add value to your property and meet your practical needs. Our Real Homes Extension Calculator helps you estimate the costs involved in extending your home, including building costs, planning fees, and potential value increase.

How the Calculator Works

The calculator estimates the total cost of extending your home by considering several key factors including the size of the extension, building materials, labor costs, and planning fees. The formula used is:

Total Extension Cost = (Building Area × Building Rate) + (Planning Fee) + (Other Costs)

The building rate varies depending on the type of extension and the materials used. Planning fees are typically a percentage of the building cost or a fixed amount, depending on local regulations. Other costs may include architectural fees, surveying, and landscaping.

Key Factors in Home Extension Costs

Several factors influence the cost of extending your home:

Building Area: The size of the extension in square meters or square feet.
Building Rate: The cost per square meter or square foot for building materials and labor.
Planning Fees: Fees charged by local authorities for planning permission.
Materials: The type of materials used (e.g., brick, timber, or modern materials).
Labor Costs: The cost of labor for construction and installation.
Other Costs: Additional expenses such as architectural fees, surveying, and landscaping.

Example Calculation

Let's consider an example where you want to extend your home by 50 square meters with a building rate of £150 per square meter, a planning fee of £2,000, and other costs of £3,000.

Total Extension Cost = (50 × £150) + £2,000 + £3,000 = £7,500 + £2,000 + £3,000 = £12,500

This example shows that the total cost of extending your home would be £12,500.

Planning Fees and Permits

Planning fees vary depending on local regulations and the type of extension. In some areas, planning fees are a percentage of the building cost, while in others, they are a fixed amount. It's important to check with your local planning authority for the most accurate information.

Tip: Consider consulting with a local architect or planning consultant to ensure you meet all local regulations and minimize costs.

Financing Your Home Extension

There are several financing options available for home extensions:

Personal Loans: Unsecured loans from banks or credit unions.
Home Equity Loans: Loans secured against the equity in your home.
Mortgage Extension: Extending your existing mortgage to cover the extension costs.
Savings: Using your own savings to fund the extension.

Each financing option has its own advantages and disadvantages, so it's important to consider your financial situation and choose the option that best suits your needs.
