Planning a house extension is one of the most effective ways to add space, increase your property’s value, and create a home that works better for you and your family. Whether you’re adding a new kitchen-diner, extra bedroom, or a spacious home office, a well-executed extension can transform how you live.
At Image Home Improvements, we’ve helped homeowners across Norfolk turn ideas into reality with practical, high-quality extensions. Here are seven top tips to consider before you get started:
1. Set a Realistic Budget (With a Contingency)
Before you draw up plans or get excited about Pinterest boards, work out how much you can afford. Remember to factor in not just the build cost but also planning fees, architectural drawings, structural engineer input, materials, and VAT.
Top Tip: Always include a 10–15% contingency fund for unexpected costs – they almost always crop up.
2. Understand Planning Permission Rules
Not all extensions need planning permission, especially under Permitted Development Rights, but larger or more complex builds may. If your property is listed, in a conservation area, or subject to an Article 4 Directive, you’ll definitely need approval.
Need help? We guide clients through the planning process and liaise with local authorities when needed.
3. Choose the Right Type of Extension
Side return, rear extension, wraparound, or even a double-storey build — the type of extension should reflect how you live and what you want to achieve.
Do you need open-plan family living? A home office? A guest suite? Think long-term and plan for future needs, not just your current wishlist.
4. Work With Professionals From the Start
Architects, builders, and structural engineers play a crucial role in ensuring your extension is safe, stylish, and structurally sound. At Image Home Improvements, we offer a full design-and-build service to keep everything under one roof, ensuring a smoother process and better results.
5. Don’t Overlook Building Regulations
Even if you don’t need planning permission, you’ll still need to comply with Building Regulations. These cover structural safety, insulation, electrics, plumbing, ventilation, and more.
We ensure every build meets and exceeds the latest standards, giving you peace of mind and full certification upon completion.
6. Maximise Natural Light
One of the biggest advantages of extending is the ability to flood your home with natural light. Consider skylights, bi-fold doors, and large windows to connect your new space to the outdoors and make it feel even bigger and brighter.
Top Tip: South-facing extensions may benefit from built-in shading or smart glass to reduce overheating.
7. Think About Flow and Layout
An extension shouldn’t just be bolted on — it should enhance the flow of your entire home. Consider how the new space will connect with existing rooms, doorways, and your garden.
We can help redesign adjoining areas if needed to ensure the extension feels like a natural part of your home.
