What Are the Average Costs for Different Types of Extensions?
Since the types and scales of house extensions vary, so do the costs you pay for them. Therefore, we’ll shed light on different house extensions and what the construction company will charge you for that.
Single-Storey Extension Costs in 2024
A single-storey extension is a popular choice for adding extra space to your home. In 2024, the average cost per square metre ranges from £1,800 to £2,500. So, if you’re considering a 20-square-metre extension, you might expect to pay between £36,000 and £50,000. These figures include materials, labour, and basic finishes. If you’re considering a compact solution, a 3 meter house extension is a popular choice that can significantly enhance your living space without overwhelming your budget.
Understanding the house extension cost per m2 is essential for homeowners planning an extension. Typically, the cost can range from £1,500 to £3,000 per square metre, depending on several factors. Single-storey extensions often fall on the lower end of this scale, while double-storey or more complex designs may command higher prices due to the additional materials and labor required. Moreover, geographic location plays a significant role, with urban areas, especially London, seeing elevated costs due to increased demand for skilled labor and resources. By grasping these per square metre costs, homeowners can better estimate their overall budget and make informed decisions regarding their extension project.
Double-Storey Extension Expenses
Adding a double-storey extension provides even more space and can be more cost-effective per square metre. The average cost per square metre is slightly lower, ranging from £1,500 to £2,200. For a double-storey extension of 40 square metres (20 square metres per floor), you might be looking at £60,000 to £88,000.
Costs for Kitchen, Bathroom, and Loft Extensions
The place you want to alter and expand will determine the house extension cost you bear, so let’s take a look at the numbers for different rooms.
Kitchen Extensions
Kitchen extensions are among the most sought-after. The cost per square metre is higher due to the need for plumbing and high-quality finishes. You can expect to pay between £2,000 and £3,000 per square metre.
Bathroom Extensions
Bathrooms require specialized plumbing and waterproofing, with costs ranging from £2,000 to £2,800 per square metre.

What Are the Key Factors Influencing House Extension Costs in 2024?
You can have a ballpark figure in mind for the cost of house extension but unless you’re clear of the materials and customization you want, the estimate will be vague. To avoid that, let’s look at the factors that impact how much you pay out of pocket for house extension in the UK:
Material Prices
The cost of building materials is a major component of your budget. In recent years, prices for materials like timber, steel, bricks, and cement have fluctuated.
- Timber and Steel Prices: Due to supply chain issues and increased demand, timber and steel prices have seen big changes. So if your extension requires structural elements made from these materials, this will affect your costs.
- Bricks and Cement: The cost of bricks and cement can vary based on availability and regional production. But local sourcing might reduce expenses.
Labor Rates
Labor costs are the most substantial part of your extension expenses because the scope of your house extension project will decide this cost.
- Regional Variations: In areas like London and the Southeast, labor rates are higher due to the cost of living and demand for skilled workers.
- Skill Level Required: Specialized work, such as intricate carpentry or bespoke installations, may increase labor costs because they require highly skilled professionals.
Location
Besides the materials you opt for and the labor costs, your property’s location will also influence extension costs.
- Urban vs. Rural Areas: Extensions in urban areas, especially in cities like London, tend to be more expensive due to higher labor rates and material costs.
- Accessibility: If your property is difficult to access, perhaps on a narrow street or a remote area, transporting materials and equipment can increase costs.
- Local Regulations: Different councils may have varying fees for planning permissions and inspections, affecting your budget.
