Types of loft conversions: Dormer, Hip to Gable and Mansard

Types of Loft Conversions

The Different Types of Loft Conversions

There are different types of loft conversion that you can have built on your house, the main three types are Dormer, Hip to Gable and a Mansard conversion. The different types of loft conversion that is suitable for your property will depend on many different aspects of your loft. For example the size or square footage, what you’re looking to get out of your conversion as well as the planning permission that is likely to be granted (if necessary)

Dormer Loft Conversion

This is the most common type of loft conversion as it is unlikely that you will need to obtain planning permission for it. This type of conversion can also be gable or have a hipped roof. A Dormer loft conversion includes a vertical wall from the bottom of your sloping roof. A flat roof is then built to meet the vertical wall, this allows us to give maximum headroom in the new loft extension.

Hip to Gable Loft Conversion London

Hip To Gable Conversion

When using this type of conversion planning permission may be required however this type of conversion gives lots of head space and is suitable for a variety of different uses such as a children’s playroom, an office or a living/social room. This type of conversion is only suitable for people with a detached, semi detached or a bungalow. Hip to gable loft conversions look to maximise a smaller existing space of properties with hipped roofs. The sloping side of a roof is changed to a flat gable end to increase the overall space within the conversion.

Mansard Loft Conversion in London

Mansard Loft Conversion

This is a very common method of loft conversion in more built up urban areas where terraced houses are more common. This type of conversion will most likely need to have planning permission from your local planning office and windows within this type of conversion will be housed within dormers. For a mansard loft conversions the dual-party or gable walls (depending on whether you live in a terraced or detached property) require to be raised to make a somewhat vertical – at least 72° – profile for the mansard. A horizontal cross section and timber framing is then added.

Roofline Loft Conversion

A Roofline loft conversion is the most popular type of conversion. This type of conversion doesn’t require any modification to the roof, as the existing roof stays as it is. This is the most popular type of conversion due to the fact of the lower price as well as it not requiring any planning permission. If you are looking for a bit of extra space for a nursery or office this would be a fantastic choice. This type of conversion is sometimes called a Velux conversion.

L Section Conversion

L Shaped dormers are becoming increasingly popular especially within the more compacted areas around London. With an L Shaped conversion you have lots of additional space for an extra room or even an en suite.
