Types of Houses for Loft Conversion

With a rich experience spanning 15 years, Fittra has had the privilege to work on diverse house types across London.


We understand the architectural quirks and advantages of each, crafting loft conversions in London that respect the original building’s spirit and inject a fresh breath of life into it.


Here’s a brief overview of some popular house types we’ve converted:


  • Victorian: Characterised by high ceilings and period features, Victorian homes offer ample loft conversion potential. We respect their heritage while creating a modern, functional space.

  • 1920s – 1930s: Known for their larger floor plans and bay windows, these houses provide plenty of room for creative loft conversions. Our team draws upon the unique layout to maximise your new living area.

  • Semi-Detached: Commonly found across London, semi-detached homes often benefit from side extensions and loft conversions. We seamlessly integrate the new space to maintain the property’s symmetry.

  • Conservation Areas: While loft conversions in these areas may be more regulated, Fittra has ample experience navigating planning permissions to deliver stunning and compliant results.


Whether you own a classic Victorian or reside in a conservation area, Fittra is your trusted partner for any London loft conversion. Let us transform your house into a dream home.

Requirements for Loft Conversion

Creating a successful loft conversion in London involves meeting some essential requirements.


One fundamental factor is the availability of a minimum head height of 2.2 m. This is crucial to ensure enough space for a comfortable living area once the conversion is complete.


However, what if your current loft height is below 2.2 m? Don’t worry – Fittra is well-versed in overcoming such challenges.


Some options include removing a roof section or lowering the room’s ceiling below. We analyse your home’s structure and devise solutions that meet general requirements and align with your visions.


Remember, with the right team of loft builders; there are ways to turn even the seemingly impossible into reality.

Step 3:

The final step of the process is the transformation of your loft into a comfortable living space. Our loft conversion builders complete the construction, interior finishes, and clean-up, ensuring your new loft is ready to use.

Loft Conversion Regulations and Permissions

One of the most common questions is whether planning permission for a loft conversion is required. Under current building regulations, planning permission is not required, provided the proposed plans fall within the permitted development loft conversion definition.


Some of the limits and conditions in place for your project to fall within the permitted development definition include the following:

  • A volume allowance of the additional space which will be created (40 cubic metres for terraced houses, 50 cubic metres for semi-detached and detached houses).
  • Materials used to clad the exterior must be similar in appearance to the existing structure.
  • Any balconies or verandas are not allowed.
  • The structure must not be higher than the highest part of the roof.
  • Any side-facing windows must be glazed, and any side-opening windows must be 1.7 metres above the floor.
  • Roof extensions are not permitted in conservation areas.
