The Average Cost of a House Extension in London

Before you start sketching your dream extension, it's essential to have a realistic budget in mind. As of 2023, the average cost of a house extension in London ranges from £1,200 to £2,500 per square meter. Now, this is a broad range because several factors influence the cost. Let's take a closer look:

1. Size Matters

Naturally, the size of your extension plays a significant role in the overall cost. The more square meters you add, the higher the bill. But don't worry; it's all about finding the right balance between space and budget.

2. Location, Location, Location

London is a city of diverse neighborhoods, and construction costs can vary greatly depending on where you live. Central London tends to be more expensive than the outskirts, so keep that in mind when planning your extension.

3. Design Complexity

The design of your extension can also impact costs. Intricate architectural details, custom finishes, and unique features can add to the price tag. However, a well-thought-out design can also increase the value of your home.

Breaking Down the Numbers

Let's get into the nitty-gritty and break down the costs of a typical house extension project in London:

  • Basic Extension: For a simple, single-story extension, you can expect to pay around £1,200 to £1,800 per square meter. This includes standard finishes and materials.

Additional Costs to Consider

Remember that the cost of the actual construction is just one piece of the puzzle. Don't forget to budget for these additional expenses:

  • Architect Fees: Architects typically charge a percentage of the overall construction cost, which can range from 10% to 15%.

  • Planning Permission: Depending on the size and scope of your extension, you might need planning permission, which comes with its own costs.

  • Building Regulations: You'll also need to comply with building regulations, and there may be fees associated with inspections and approvals.

  • Interior Design and Furnishing: Once the construction is complete, you'll want to furnish and decorate your new space, which can add to the overall cost.

A Friendly Reminder: Value Over Cost

While cost is undoubtedly a significant factor, remember that a well-executed house extension can add substantial value to your London property. It not only enhances your living space but also increases your home's market value, making it a smart long-term investment.
