Types of Loft Conversion in the UK


If you need more space in your home and are not looking to move out either, converting your loft is the most cost-effective solution for you. You don’t have to worry about estate agency fees, solicitor fees, moving costs and stamp duty payment.


You’ll find many types of loft conversions in the UK. At Loft Conversion Experts Cardiff, we provide:

  • Hip to Gable
  • Dormer
  • Mansard
  • L-shaped Mansard
  • Velux


Hip to Gable Conversion


One of the most popular choices for semi-detached properties that provides maximum space. It creates more space on the slopping side of the house by replacing the slopping roof and extending it towards the outside wall where a gable wall is built. This way, the space created is maximized and opens up for a new staircase to be placed above the existing one.


Dormer Conversion


Dormer loft conversions are also popular among semi-detached houses. It’s a structural extension that is developed from the plane of the roof. When existing loft space is of insufficient size for the proposed conversion, this option is preferred. With this conversion, additional headroom for both the staircase and the new living space is created.


Dormer loft conversions are popular due to the increased space and light they can create in your room. They are feasible for most properties, even terraced and detached homes, making it one of the most flexible options available for homeowners.




Mansard lofts are named after the 17th-century French architect Francois Mansard.


For areas of the house where careful planning is required for extensions, Mansard loft conversion is preferred. Due to the delicacy, it requires a lot more actual planning and designing, but the end result will be a much bigger living space. It can be built across the entire roof space of your house, which means it is ideal for terraced properties.


In London, where every piece of property is at a premium, Mansard loft conversion can be used to make the best of what you have. Even in Cardiff where the pricing of housing is cheaper, it’s definitely still a great way to add room and value to your property.


L-Shaped Mansard


L-shaped mansard loft conversions work very well for converting the loft into an open-plan en-suite bedroom. They can considerably increase the available space, and can also increase the value of the house as well.


Double Mansard


Double mansard loft conversion is similar to a standard mansard but differs by adding another mansard to the front.


With a double mansard loft conversion, you can take advantage of a larger square space, since both sides of the roof will be opened, adding a Mansard onto both sides.


However, with this loft conversion option, a complete change to both sides of the roof will occur. Hence, in some cases there may be restrictions on changing the front design of your roof type, so even with proper planning it might be difficult to gain a double mansard conversion.




This option is also known as Roof Light conversion and is preferred when a smaller loft conversion contained within the roof line is required. Therefore, it is suitable for a single bedroom, playroom or study where enough room is already available within the existing loft space. Roof lights can be installed with minimal hassle.


How Difficult Is It To Get A Loft Conversion?


Once there has been an agreement on the loft conversion type, we will advise our clients about the legal requirements needed for a loft conversion. Planning out your loft conversion for a smooth process is of utmost importance to us.


As house planning laws were relaxed in 2008, most houses now have separate permitted development rights for the roof.
