Need more space for relatives visiting during the holidays, a hangout for your children, or a comfortable room for adult children living at home? A roof extension is one of the best solutions.
It’s not just a renovation — it’s a way to add long-term value, extra space, comfort, and even improve your home’s energy rating.

Why it is a great solution
Extra space for everyone: Create a welcoming bedroom for guests, a playroom for children, or a private space for grown-up children.
Energy-smart upgrades: New windows and insulation can improve your home’s energy rating, lowering costs and boosting resale value.
Better everyday living: More room means less clutter, more comfort, and a home that adapts to your family’s lifestyle.
With the right plan, you could enjoy a bright, extra room without stretching your budget.
Can you make it happen without savings?
You don’t need to wait for savings. Financing a roof extension through your mortgage (bouwdepot or overvaarde) can make it surprisingly accessible.
- Monthly payments can start from around €40–€80, depending on your loan and the size of the extension.
- Early repayment is usually possible, giving you flexibility as your plans evolve.
Tips for Doing It the Right Way
Adding a roof extension can be exciting, but there are some important things to keep in mind to avoid stress and extra costs:
- Always check if you need a permit
- Back of the house: While some extensions at the back of the house may not require a permit, rules vary by municipality.
- Front of the house: If your home faces a street, park, or water, a permit is often required.
- Avoid building without permission
- Constructing without a permit can lead to fines or even the requirement to remove your new roof extension, which is expensive and stressful.
- Plan for long-term comfort
- Think about how you’ll use the space: guest bedroom, teen hangout, office, or space for adult children..
- Work with experts
- Experienced professionals can help navigate permits, design, and construction. This avoids common mistakes and ensures your project is safe, compliant, and efficient.
