A guide to extending your property

Extending your home is a popular way to add value and space without the need to relocate. With a varied housing market and fluctuating property prices, many owners opt to enhance their existing homes through extensions. This approach not only potentially increases their market value but also adapts them to evolving lifestyle needs. Understanding the costs, legalities, and practical considerations involved is crucial for a successful project. There’s a lot to take into account when embarking on a renovation, so here are a few helpful tips to offer some guidance.


Understanding the legal requirements

Before you get started, it’s essential to navigate the legal landscape. You must secure the necessary planning permissions and comply with building regulations. These ensure that the extension is safe, efficient and in harmony with the surrounding area. Specific rules can vary by location, so it’s important to consult with local authorities or hire a professional, such as a conveyance, to help with this aspect. They should be able to provide expert guidance, but if they fail to identify or mention a key piece of legislation that you later fall foul of, you could have grounds to make a conveyancing claim to try and recoup some of the financial damages you may suffer.


Budget planning

The cost of extending a home can vary significantly based on factors like location, size and chosen materials. In 2024, a basic single-story extension might cost between £1,200 and £1,500 per square metre, while more complex or larger projects could range from £1,500 to £2,500 or more per m2. Effective budget management involves detailed quotations, a clear understanding of potential overruns and contingency planning.


Design and aesthetics

Your extension needs to complement the existing structure and meet your needs. It should enhance the property’s aesthetics while also being functional. Choices about materials and design features significantly impact the costs and the final look. It’s often beneficial to employ an architect to successfully merge these practical and stylistic elements.


Choosing the right contractor

This aspect is pivotal. It’s advisable to choose someone reputable, with the necessary credentials and positive feedback from previous projects. Detailed contracts should be drawn up to outline the scope, timeline and costs, helping to mitigate potential disputes and ensure clarity for both parties.


Managing the project

This involves regular communication with the contractor, tracking the budget, and managing any disruptions that occur during the construction phase. You also need to prepare for the work’s impact on your life, which might include a temporary relocation or adjustments to daily routines.


Extending a property is a significant undertaking that, when done right, can provide substantial benefits. It requires thorough preparation, from understanding legal and financial implications to ensuring the project is completed to a high standard. But with the right approach, you can enjoy a more spacious and valuable property for years to come.
