Common questions about house extensions

If youโ€™re thinking about extending your home, you probably have plenty of questions. Our FAQs cover the things homeowners ask mostโ€”planning, timelines, cost, design and comfortโ€”so you can feel confident and informed before getting started on your dream extension.

1. Do I need planning permission for a house extension?

Not always. Many extensions fall under permitted development if they meet size and height rules. However, larger builds, certain locations or homes with previous extensions may require full planning approval. 5 Star check everything for you and handle all applications to ensure your project runs smoothly and compliantly.

2. How long does a typical house extension take to build?

Build times vary depending on size, design and complexity. Most extensions take between 8โ€“12 weeks from groundwork to completion. Faster modern systems such as hup! can significantly reduce installation time. 5 Star provide a clear timeline during your survey so you know exactly what to expect.

3. Will an extension add value to my home?

Yes. A well-designed extension that adds functional living space – such as a kitchen, dining room or home office can significantly increase resale value and overall appeal. Buyers look for modern, open-plan layouts and energy-efficient spaces, making a quality extension a strong long-term investment.

4. Can I live in my home while the extension is built?

In most cases, yes. Extensions are usually built externally first, minimising disruption to your daily life. Some internal work may require brief access inside, but 5 Starโ€™s teams always work cleanly, safely and with careful planning to keep interruptions to a minimum.

5. What type of extension is best for my home?

It depends on your goals. Rear extensions are great for larger kitchens or dining rooms, side extensions make use of unused space, and wrap-around extensions transform layout completely. 5 Star designers help you explore options based on budget, layout and how you want to use the space.

6. How energy-efficient will my new extension be?

Modern extensions use high-performance insulation, energy-efficient windows and advanced roofing systems to deliver excellent thermal performance. This keeps the space warm in winter, cooler in summer and comfortable all year. 5 Star also offer upgraded glazing and roofing options to boost efficiency even further.

7. How much does a house extension cost?

Costs vary depending on size, materials, roofing, foundations and interior finish. Smaller extensions can be surprisingly affordable, while large open-plan spaces may require more structural work. 5 Star provide tailored quotations, transparent pricing and flexible finance options to help you achieve the extension you want.

8. Can you design the extension to match my home?

Absolutely. You can choose brickwork, roofing, glazing, windows and doors to seamlessly complement your property. Whether you prefer a modern look or something more traditional, 5 Star create fully bespoke designs that feel like a natural, high-quality extension of your home.
