Understanding Average Extension Costs

The cost of a house extension varies, but in the UK, the current cost benchmark is £2000/m2. This range depends on the materials, design, and type of extension. For example, single-story extensions are usually cheaper than multi-story ones.

Keep in mind that extension construction costs can go up because of architectural fees, planning permissions, and extra work like new roofing or foundations. Knowing these factors helps you plan your budget better.

Key Factors Influencing Extension Cost

When planning a home extension, several important factors affect the price:

Size and Type

The larger the extension, the more it will cost.

Affordable home extensions, including ground-floor extensions, are usually cheaper than building up.

Location

Where you live matters. Extensions in urban areas tend to cost more due to higher demand and living costs.

Materials

The materials you choose can impact the budget. High-quality materials cost more but last longer and look better.

Labor

The cost of skilled workers can vary by region. Getting multiple quotes helps you find the best price.

Permits and Inspections

You’ll need permits for your extension. Don’t forget to factor in the cost of HUD inspections, as they can add to your total.

Hidden Costs You Should Consider

Besides the main costs of building your extension, there are some hidden expenses to keep in mind. These include:

  • Planning permission fees
  • Surveying costs
  • Utility adjustments

It’s important to have a contingency budget for any unexpected expenses during the building process. A good rule is to set aside about 10% of your overall budget for these surprises.

The Benefits of Planning Wisely

Planning your extension carefully can save you significant amounts of money in the long run. For example, clearly defining what you want from the extension and discussing your ideas with architects and builders upfront can lead to more precise quotes and avoid costly design changes later.
