What are the different types of Loft Conversions?

UK homes have four main types of attic conversions. Extending into your attic gives you space that could be used as a guest bedroom, a study or a playroom, which adds expansive floor space and extra value to your property. The cost depends on factors like location and size and could cost between £20,000 to £45,000. Timescale is around 4 to 8 weeks to convert your empty roof space into a loft.

To decide what sort of conversion is best for you, key considerations include the following:

  • The shape and line of your current roof
  • Your budget 
  • Your permitted development rights 

An architect can work with you to understand how to draw the best plans for your home. But if you need more information to inform your decision, there are three basic types of alterations to your structure:

Dormer Loft Conversion North London

Dormer Loft Conversion

This is the most popular type of loft conversion. A simple flat roof dormer is a structural extension which projects vertically from the slope of the current roof. This creates a box shape. This loft extension is very popular as no dramatic changes are required, and allows for the installation of conventional windows.


  • It adds useful headroom and extra space in a confined attic
  • Straight walls and flat ceilings are 
  • Good light and ventilation
  • Cheap option
  • Is suitable for most UK homes


  • Isn’t always an appealing choice aesthetically 

Another variation on a dormer is an L-shaped dormer, which wraps around the side and back of the property. It is a popular choice and works well with mid-terraced properties. A gabled dormer is another popular choice; its traditional inverted “V” shaped roof is a more visually pleasing choice for the front of the property but can be a more expensive option.

Mansard Loft Conversion

A Mansard loft conversion is formed by raising the party wall (the wall you share with your neighbours), and as one outer wall slopes inwards, the roof remains flat. Mansard conversions are usually found at the rear of the property, and are most popular in terraced houses, but they can be found in many types of properties.


  • More aesthetically pleasing than a dormer
  • Works well with older properties
  • More headroom than other types of conversions
  • Usually allows more light into your loft


  • Planning permission tends to be essential 
  • Constructing the build can be longer than other types of conversion
  • Tends to be more expensive than other conversions

Roof Light Loft Conversion

Roof Light Loft Conversion

Can also be known as Velux Loft Conversions due to the popularity of the integrated roof based windows. This is where you don’t alter the existing space, just add in windows and reinforce the floor. This transforms an attic into a comfortable living space.


  • Can be 25% cheaper than other conversions
  • Better chance of approval in conservation areas
  • More storage room if you use your eaves creatively


  • Needs a minimum 2.25m of head height in the middle of the room to build up the floor
  • Doesn’t open up any more useful space in comparison to other conversions 
  • Can be limited headroom 
  • May still require planning permission if windows are located at the front

Hip to Gable Loft Conversion

The best choice for end of terrace and detached homes, becoming very popular with many homeowners and can make a big difference to the feel of your living space.

This type of loft extension straightens an inwardly slanted end roof, making a vertical wall. 


  • Blends in with the existing home aesthetics seamlessly  
  • Combined with a rear dormer loft, it can create maximum space
  • A great choice for bungalows and chalets


  • Not suitable for mid-terrace homes
  • Is more expensive than a dormer conversion
