There are several benefits of adding a loft conversion to your home, including extra space, energy efficiency and better lighting. Moreover, a recent study suggested that a UK loft conversion can add more than 20% value to your home. As such, loft conversions are becoming more and more popular.

There are four main types of loft conversion, each with their own individual characteristics andit is worthwhile doing some research to help determine which type is right for your living space.

1. Roof light conversions

A roof light conversion is one of the most popular options, particularly as it does not require the need to extend the external space, dramatically reducing overall costs and building disruption. This type of conversion simply entails building a sky light within the existing roof structure and a staircase to enter the new room.

Roof light conversions are desirable as they tend to provide lots of extra natural light, cutting down energy costs and making the room brighter. However, it is worth bearing in mind that if you are seeking more space, a roof light conversion may not be the right choice for you as they don’t actually extend the build size.

2. Dormer conversions

In the UK, a flat roof dormer conversion is the most popular type, due to its relatively inexpensive price tag and the large amount of extra internal space it provides. Dormer conversions are loft extensions which protrude vertically from sloping roof planes, enabling tight loft spaces to be converted into spacious habitable rooms. For this type of conversion, planning permission is usually not necessary.

3. Mansard conversions

These are typically the most expensive type of loft conversion, requiring structural alterations to the existing property through extension of the entire roof plane. In essence, the whole roof structure and shape is changed, effectively creating an extra storey to the property.

As such, this type of conversion will usually require local authority planning permission to go ahead. However, the end result will mean a significant amount of added space, making them the best choice for those who are considering a loft conversion for that very reason.

4. Hip to gable conversions

In most properties, the structure of the roof is ‘hipped’, meaning the sides slope, resulting in limited habitable space. Hip to gable conversions fix this problems by extending the roof on its sloping side and replacing it with a vertical wall at the end. As such, these are usually carried out on roofs that have three side slopes, so they won’t be suitable for mid-terraced houses.

Planning permission is not typically required for this type of conversion, falling under the ‘permitted developments’ category. Always be sure to double-check with your local authority before having any extension work carried out though.
