Introduction
Building a home extension is one of the best ways to add space and value to your property — without the hassle of moving. Whether you’re planning a larger kitchen, an extra bedroom, or a stylish open-plan living area, a well-planned extension can transform the way you live.
At Alleshi Construction, we’ve completed dozens of extensions across London and Essex. Here are the five key things every homeowner should consider before starting their extension project.
1️⃣ Understand Your Budget
Before you start designing, it’s important to set a clear and realistic budget.
Consider:
- Construction costs (materials, labour, finishes)
- Professional fees (architects, planning, building control)
- Unexpected expenses (contingency for surprises once work begins)
At Alleshi Construction, we always provide transparent, detailed quotes so you know exactly where your money goes — no hidden costs or unpleasant surprises.
2️⃣ Check if You Need Planning Permission
Depending on your property type and size of the extension, you may need planning permission from your local council.
Some smaller extensions fall under Permitted Development Rights, which means they don’t require formal approval — but it’s always best to check.
Our team can help you navigate the process and ensure your project complies with all UK planning and building regulations.
3️⃣ Choose the Right Design and Layout
Think carefully about how you’ll use your new space. A great design isn’t just about square footage — it’s about functionality, light, and flow.
Consider how the extension connects to your existing rooms and garden, and how natural light can enhance your living areas.
Our designers and builders work closely with you to create an extension that’s both practical and beautiful.
4️⃣ Select Quality Materials
Using high-quality materials pays off in the long run — they last longer, look better, and add more value to your home.
From durable brickwork to energy-efficient glazing, we source materials from trusted UK suppliers to ensure your extension stands the test of time.
5️⃣ Work with an Experienced Contractor
Your choice of builder can make or break your project.
