For many homeowners, extending their property is an good way to create extra space and potentially boost its value. But how much does an extension really add to your property, and is it worth the investment? 

How Much Value Can an Extension Add?

On average, a well planned property extension can increase your home’s value by 10-20%, depending on the type of extension and your location. For example:

  • Kitchen Extensions: A spacious, modern kitchen can add around 15% to your home’s value, especially in areas where large kitchens are a key selling point.
  • Loft Conversions: Adding a bedroom and en suite through a loft conversion can boost your property value by up to 20%.
  • Single Storey Extensions: A rear or side extension often adds around 10-15%, making it a popular choice for homeowners.

However, these figures depend on various factors, including the size, quality, and functionality of the extension, as well as the demand for properties in your area.

Costs to Consider

Extensions aren’t cheap, and the costs can vary widely. On average, homeowners spend between £1,500 and £2,500 per square metre for a single storey extension. Loft conversions typically cost between £30,000 and £50,000, depending on the complexity of the design.

Other expenses to factor in include:

  • Planning Permissions and Permits: These can cost between £200 and £500, depending on your local council’s regulations.
  • Furnishings and Finishing Touches: Budget for interiors and decor, which can easily add a few thousand pounds to the final cost.

Delays and unforeseen complications can lead to overspending, so it’s vital to account for a contingency fund when budgeting. A good rule of thumb is to set aside at least 10% of the projected costs for unexpected expenses.

Are Extensions Always Worth It?

The key to maximising the return on investment from an extension is to plan carefully and ensure the work enhances the property’s appeal. Ask yourself:

  1. Does the Extension Add Practical Value? Extra bedrooms, bathrooms, or open plan living spaces are highly sought after by buyers.
  2. Is the Cost Manageable? Ensure the extension won’t overcapitalise your property spending more than the market value can absorb.
  3. What’s the Local Demand? Research property values in your area to understand how much your extension could increase your home’s worth.

A property extension can be a worthwhile investment if done right, offering both practical benefits and a potential value boost. However, careful planning and budgeting are essential to ensure you get the most from your investment.
