A house extension is a fantastic way to add space and value to your home, whether it's a larger kitchen, an extra bedroom, or even a home office. But before jumping in, careful planning is essential to ensure a smooth and stress-free build. Horizon Developments have been helping homeowners extend and transform their properties for over 30 years. Here’s a step by step guide to planning a house extension the right way.

1. Define Your Goals

Before anything else, it’s important to ask: What do you want from your extension? More space for a growing family? A stylish open-plan kitchen? A dedicated work-from-home area? Defining the purpose will help shape the design, budget, and overall plan.

2. Set a Realistic Budget

House extensions come with a range of costs, from planning permission to materials and labour. It’s crucial to set a budget early and factor in unexpected expenses. Horizon Developments always recommends allowing a contingency fund—because, let’s be honest, building work rarely goes 100% to plan!

3. Check Planning Permission & Regulations

Not all extensions require planning permission. Smaller projects might fall under permitted development rights, but it’s always best to check with the local authority. Building regulations also need to be met, ensuring the structure is safe and energy-efficient. The team at Horizon Developments is well-versed in local building rules and can guide homeowners through the process.

4. Get the Right Design

The design of your extension should complement your existing home while maximising natural light and functionality. Working with experienced professionals will help bring ideas to life, ensuring the extension is both practical and aesthetically pleasing. Horizon Developments can recommend trusted architects and designers to create plans tailored to each homeowner’s needs.

5. Hire a Reputable Builder

Choosing the right builder is arguably the most important step. A reputable company will ensure the project runs smoothly, stays on budget, and is completed to a high standard. Horizon Developments has built a solid reputation as trusted house extension specialists, with highly skilled tradesmen and a commitment to quality. They also encourage potential clients to view previous projects or speak to past customers for peace of mind.

6. Plan for Disruption

Living through a house extension can be messy, noisy, and sometimes stressful. Homeowners should consider how the work will affect daily life—especially if it involves structural changes like knocking through walls. A good builder will work efficiently to minimise disruption, keeping the process as hassle-free as possible.

7. Think About the Finishing Touches

Once the structure is complete, attention turns to the finishing touches—flooring, lighting, paint colours, and furnishings. These details bring the space to life, making it feel like a natural extension of the home. Horizon Developments can also assist with hard landscaping, such as patios or driveways, to complete the project inside and out.

8. Enjoy Your New Space!

After all the planning, budgeting, and building, the best part is enjoying the finished extension! Whether it’s hosting family gatherings in a spacious new kitchen or relaxing in a sunlit lounge, the investment is always worth it.
