How much does a house extension cost?

Understanding House Extension Costs: A Comprehensive Guide

When considering a house extension, one of the most common questions that arises is: How much will it cost? The answer can vary significantly depending on a range of factors, including the type of extension, location, materials, design complexity, and more. To help you gain a better understanding of house extension costs, we'll explore the pricing landscape, including the range between £2500 and £3000 per square meter (£/m²).


Factors Affecting House Extension Costs:


Type of Extension: Different types of extensions come with varying costs. Single-story, double-story, wrap-around, and rear extensions each have their own price considerations based on the added square footage and structural modifications required.

Size: The size of the extension is a major determinant of cost. Larger extensions naturally require more materials and labour, leading to higher costs.

Materials: The choice of materials impacts both the aesthetics and cost of the extension. High-end finishes and bespoke elements will increase the overall budget.

Location: Costs can vary depending on the area where you're located. Factors such as local labour rates, access to materials, and planning regulations can influence pricing.

Design Complexity: Intricate designs and unique architectural features may require more time and skill to execute, contributing to higher costs.

Site Conditions: If the construction site presents challenges such as uneven terrain, poor access, or difficult ground conditions, these factors can affect costs.

Services: If the extension requires additional utilities, plumbing, electrical work, or HVAC systems, the cost will naturally be higher.


Price Range: £2500 - £3000 per m²


For the purposes of this guide, let's consider a price range between £2500 and £3000 per square meter (£/m²). Keep in mind that this range is an estimate and that actual costs may fall outside of it based on the factors mentioned above. Here's how this price range might apply to different scenarios:

Small Single-Story Extension: If you're adding a relatively simple single-story extension of around 20m², the cost might fall within the £50,000 to £60,000 range (£2500 - £3000 per m²).

Medium Double-Story Extension: For a larger double-story extension of around 40m², the cost could range from £100,000 to £120,000 (£2500 - £3000 per m²).

Complex Wrap-Around Extension: A more complex wrap-around extension of approximately 60m² could fall in the range of £150,000 to £180,000 (£2500 - £3000 per m²).


It's important to remember that these figures are rough estimates and don't include additional costs like planning fees, design fees, or finishing touches such as fixtures, fittings, and interior design.


Getting an Accurate Quote:


For a precise understanding of the cost of your specific extension project, it's recommended to consult with experienced builders, architects, or contractors. They can provide you with a detailed breakdown of costs tailored to your requirements and location. A comprehensive quote takes into account your design preferences, materials, site conditions, and any additional services needed.


In conclusion, the cost of a house extension varies widely based on a multitude of factors. While a price range of £2500 to £3000 per m² provides a general guideline, it's essential to work with professionals to get an accurate estimate based on your unique project. Remember, a well-executed house extension is an investment that can significantly enhance your living space, lifestyle, and property value.
