3-Meter House Extension: everything you need to know

A 3-meter house extension is a popular choice for homeowners seeking to maximize their living space without undertaking a full-scale renovation. Whether you’re looking to create an open-plan kitchen, add a cozy living area, or expand your dining space, this extension type offers a cost-effective solution to make your home work better for you.


What Is a 3-Meter House Extension?

A 3-meter house extension typically refers to an addition that extends 3 meters from the rear of a property. This size often falls within the scope of permitted development rights, meaning you may not need formal planning permission. However, specific requirements must be met, such as:

  • The extension must not exceed 4 meters in height.
  • It must not cover more than 50% of the original garden.
  • It should not be closer to a boundary than allowed under local rules.

Benefits of a 3-Meter Extension

  1. Extra Living Space: Whether it’s a larger kitchen, a playroom for kids, or a quiet home office, the additional space is highly functional.
  2. Cost-Effective: Compared to larger extensions, a 3-meter addition is more affordable and quicker to complete.
  3. Improved Property Value: Adding square footage to your home can significantly increase its resale value.
  4. Flexible Design Options: You can design the space to complement your existing home and lifestyle.


What to Consider Before Starting

1. Planning Permission

While many 3-meter extensions fall under permitted development, it’s essential to check with your local council to ensure compliance. Rules may vary depending on your property type (e.g., terraced, semi-detached, or detached).

2. Structural Feasibility

Ensure your existing home can support the extension structurally. Consulting with an architect or engineer is crucial at this stage.

3. Light and Ventilation

Consider how the extension will impact natural light and airflow. Rooflights or bi-fold doors are excellent ways to brighten the space.

4. Budget

Set a realistic budget that includes construction, finishes, and any professional fees. Unexpected costs can arise, so allow for contingency.

5. Aesthetic and Functionality

The extension should complement your home’s architecture and meet your functional needs. Balancing aesthetics and practicality is key.
