Planning a Home Extension in North London? Here’s What to Know Before You Start

Thinking about extending your home in North London? Whether you’re planning a rear extension, side return, or a full wraparound, knowing what to expect before you start can save time, money, and stress.

1. Do You Need Planning Permission? Not all extensions require planning permission, but rules vary depending on the size, location, and property type. In many cases, permitted development rights apply — but it’s always best to check before work begins.

2. Budgeting Realistically. One of the most common mistakes homeowners make is underestimating costs. A clear budget should include design, construction, materials, and a contingency for unexpected work.

3. Choosing the Right Builder Look for a construction company with experience in North London, transparent pricing, and a portfolio of completed projects. Clear communication from the start is key to a smooth build.

4. Timelines & Disruption Extensions can take several weeks or months, depending on complexity. Knowing the expected timeline helps you plan around everyday life during construction.
