Small side infill flat roof extension

If you live in London, you’ll know how precious every square meter of space is. With house prices on the rise and moving costs climbing even higher, many homeowners are opting to expand their existing homes rather than relocate. One of the smartest and most cost-effective ways to do this is through a **small side infill flat roof extension**.

What is a Side Infill Extension?

A side infill extension fills in the narrow space along the side of your house, typically in Victorian or Edwardian terraced homes. This strip of land, often overlooked, can be transformed into valuable living space. By extending into this area, you can enlarge your kitchen, dining room, or even create a cozy new living area.

Why Choose a Flat Roof?

A flat roof is the perfect companion to a side infill extension. It’s affordable, quick to construct, and adds a modern aesthetic to period properties. The flat roof also allows for skylights, ensuring that natural light floods the new space, preventing it from feeling dark or enclosed.

I recently worked with a family in Camden who expanded their small kitchen into the side return with a flat roof extension. The result was stunning — the once-cramped space was transformed into a bright, open-plan kitchen-dining area that became the heart of the home.

How Much Does It Cost?

The cost of a small side infill flat roof extension varies depending on size and finish, but here’s a rough guide:

• Basic build: £40,000 to £65,000
• High-end finish: Up to £100,000 or more

Additional costs include architect fees, planning applications, and VAT. While it may seem like a significant investment, the value added to your home often outweighs the initial cost.

Where in London Are These Extensions Popular?

Side infill extensions are common in areas with older terraced properties, such as:

• Camden Town
• Fulham
• East Dulwich
• Kensal Rise

These areas are known for their Victorian and Edwardian homes, which are ideal candidates for side infill projects.

Planning Permission and Regulations

In many cases, side infill extensions fall under permitted development, meaning planning permission isn’t required. However, if your home is in a conservation area, you may need to apply for approval. Always check with your local authority before starting.

Final Thoughts

A small side infill flat roof extension can unlock hidden potential in your home, providing much-needed extra space without encroaching on your garden. If you’re considering this type of project, consult with an experienced architect or builder to bring your vision to life.
