Demystifying House Extension Costs in 2024

Exploring Extension Types and Their Associated Costs

There are various types of house extensions to consider, with each suiting different kinds of properties and budgets. Some common types include:

• Single-storey extension: A popular choice for expanding living space, particularly for kitchen or lounge areas. Can be cost-effective when carring out a house extension in the St Albans area.
  
• Two-storey extension: Often used to expand both living and bedroom areas. Double the cost compared to single-storey extensions due to additional foundation work, materials, and labour.
• Wrap-around extension: Combines both rear and side extensions, creating a larger area around the property. Costs more than a single extension, but overall cheaper per square metre.
• Side return extension: Utilises the narrow space between properties, perfect for terraced or semi-detached houses. Costs vary based on style, materials used, and location.
  

Determining Factors Behind Extension Prices: From Labour to Materials

Several factors affect house extension costs:

• Labour costs: Professionals such as architects, builders, bathroom fitters and project managers will be charged for their time and expertise.
• Materials: The quality of materials can significantly impact the overall cost.
• Size of the extension: Larger projects will require more materials and labour, thus increasing costs.
• Extension quality: Preference for high-end finishes or fixtures may increase the total cost.

As a rough guide, building an extension usually costs around £1,500 – £3,000 per square metre, excluding VAT.

How Much Value Does an Extension Add to Your Home?

Investing in a home extension can add significant value to the property, with the potential for a higher return on investment (ROI) when selling. Factors affecting the ROI include:

• Location: Property value, demand, and regional trends in housing prices will determine the increased value from an extension.
• Design: A well-executed design can increase both the aesthetics and functionality of a space, thus increasing property value.

To better gauge the potential ROI, contact your local property experts.

Strategic Budget Planning for Your Home Extension Project

To create a realistic budget for your family home expansion, including garden room uses, start with a preliminary estimate of the build cost, add a contingency fund for unforeseen expenses, and subtract any potential grants or subsidies. Seek multiple quotes from builders and professionals to ensure accurate cost projections. Don’t forget to include VAT and legal fees in your estimate.

Navigating Regulations and Planning Permission for Your New Extension

Obtaining planning permission and complying with building regulations are essential aspects of any extension project. Consult your local council for details on legal requirements, and seek guidance from an architect or specialist to ensure compliance. Keep in mind that permitted development rights may allow you to build an extension without planning permission, depending on the project’s scope.
