Do I Need Planning Permission?

A standard home extension is usually classed as permitted development, meaning it typically doesn’t require planning permission, provided certain limits and conditions are met. We’ll guide you through these requirements in detail to ensure everything is compliant.

Benefits of a House Extension

  1. Create More Living Space - Whether you need an extra bedroom, a larger kitchen, or a more open living area, an extension offers a flexible way to expand your home to suit your lifestyle.
  2. Add Value to Your Property - Increasing your home's floor area or adding bedrooms can significantly raise its market value and appeal to future buyers.
  3. Avoid the Cost of Moving - With property prices and legal fees rising, extending your current home is often a more cost-effective and convenient alternative to moving.
  4. Adapt to Changing Needs - From growing families to accessibility requirements, a well-planned extension can help your home evolve with your circumstances.
  5. Boost Storage Options - Extensions can be designed with smart, integrated storage solutions, maximising space and reducing clutter.
  6. Personalised Design -Tailor your extension to reflect your style and needs, from layout to lighting, materials to finishes.
