5 Things to Consider When Planning a House Extension

Are you dreaming of extra living space, a larger kitchen, or an additional bedroom? A house extension can be the perfect solution to accommodate your growing needs. However, it’s essential to plan carefully to ensure a successful project.

1. Planning Permission

If you’re wondering, “Do I need planning permission for a house extension?” the answer is usually yes. While some minor interior renovations, such as redecorating a kitchen or bathroom, may not require permission, adding a new room or converting a garage into living space typically does. It’s essential to get the necessary planning approval from your local council to avoid potential legal issues or penalties.

The planning permission process can take time, so factor that into your timeline. If your initial application is denied, you may need to resubmit after considering the council’s feedback.Planning permission is required for building works that generally increase the footprint of a building over certain sizes, including new larger buildings within your grounds, or if you want to change the use of a building. Different local authorities will have different rules and restrictions. You can see the rules that apply in your area on your local council’s website.

2. Building Regulations

Even if your extension doesn’t require planning permission, it must still comply with building regulations. These regulations cover crucial aspects such as energy efficiency, damp proofing, and structural integrity, fire protection, accessibility and protection against falls, electrical and gas safety. Adhering to these regulations ensures that your extension meets the required standards set by the government.

3. Budget Considerations

When planning a house extension, it’s crucial to consider all associated costs. Your budget should account for construction costs, design fees, permits, materials, and even VAT. It may be tempting to cut corners, it’s important to remember that cutting corners comes with risks. A poorly planned house extension can lead to further expenses to cover repairs if an extension is designed poorly, and in worse case scenarios it can reduce the value of the property.

4. Additional Costs

It’s wise to set aside a contingency fund of approximately 10-20% of your overall budget. Unexpected costs can arise during the construction process, such as including extra features or changing the specification as you go along.

When estimating the cost of your new expansion, keep in mind that employing a structural engineer, architect, and surveyor will add to the overall cost. In addition to these experts, you will also need to pay for the party wall agreements, building code approvals, and necessary clearances.

5. Talk to Your Neighbours

While your neighbours cannot stop you from building on your property, having their support can make the process much smoother. Open communication and addressing any concerns they may have can go a long way in ensuring a positive experience for everyone involved.

Planning a house extension requires careful consideration of various factors to ensure a successful outcome. By addressing planning permission, adhering to building regulations, budgeting accurately, accounting for unexpected costs, and maintaining open communication with your neighbours, you can have a smooth extension process.
