If you love your home but wish you had a bit more space, you’re definitely not alone. At Bricksy, we’ve helped loads of people across London turn their houses into something that really works for them, just by adding a well-planned extension. Here, we break down the main benefits, challenges, and what you can expect when it comes to costs.
Why Extensions Are a Great Idea
- More Room to Live: Whether you’re dreaming of a bigger kitchen, an extra bedroom, or a new work-from-home space, an extension gives you that extra space without the hassle of moving.
- Adds Value: A good extension usually boosts the value of your property, so you’re investing in your future if you ever decide to sell.
- Tailored to You: Want more light, open-plan living, or just a really cosy spot to relax? You get to choose exactly how your new space looks and works for you.
- Better for Everyday Life: The right extension can make your home more practical and enjoyable every single day.
Some Things to Think About
- Planning & Permissions: Depending on what you want to build, you might need planning permission and you’ll definitely need to meet building regulations. It can seem daunting, but at Bricksy, we’re happy to guide you through it. • The Mess: Let’s be honest, building work isn’t the tidiest process. There will be a bit of disruption, but we always work to keep it to a minimum so you can get back to normal as soon as possible.
- Blending In: You’ll want your new space to look like it’s always been part of your home. That’s where our experience with design and materials comes in handy.
How Much Does an Extension Cost?
Costs can vary quite a bit, depending on how big your extension is and what features you want. To give you a ballpark in London:
- Single-storey extensions: Around £1,800–£3,000 per square metre.
- Double-storey extensions: Usually from £2,500–£3,700 per square metre.
- Extras: Things like fancy finishes, kitchens, or bathrooms can bump the price up a bit.
