What are the different types of loft conversion?

A1 Loft Conversions offer Loft Conversions in Surrey, London & surrounding areas. There are a number of types of loft conversion. Which type you have for your home will be dependent on a number of factors such as planning permission, house type, conservation areas, roof height and available space.

The main types of loft conversion are below, it is important to consider that these can then be adapted and made bespoke to suit your home:

Rear Dormer Loft Conversion

A dormer loft conversion is an extension to the existing roof, creating additional floor space and headroom within the loft conversion. Dormers can be built in various styles, but all extend from the roof slope, usually in a box shape.

The process for building a rear dormer is simpler than most extensions. Many people choose to have a  dormer because of the options it can bring. Space is a key reason for having a rear dormer extension. Whether you need a new bedroom or a study if you’re working from home, the possibilities are endless.


Mansard Loft Conversion

A mansard loft conversion has two slopes with the top section of the roof being almost horizontal.  A mansard roof has the advantage of maximizing the available space within your loft.

A mansard loft conversion has a flat roof with the back sloping inwards at 72 degrees. The reason for this is due to planning criteria as the councils view 72 degrees as a roof, rather than a wall, allowing for the build to incorporate as much space across the conversion as possible. The windows built into the loft conversion are constructed as small dormers.


Hip To Gable Loft Conversion

Most properties have a regular, ‘hipped’ roof with a sloping side. This means existing loft space is often limited, making it difficult to create a loft conversion without extending your property. This is where hip to gable loft extensions come in.

A hip to gable loft conversion involves making fairly major changes to the roof. As a general rule, houses with a hip roof tend to not have enough internal space for a loft conversion to be practical, making a hip to gable conversion the perfect solution.


Velux Loft Conversion

Velux loft conversions very rarely require planning permission. Velux are the leading manufacturer of roof windows with over 60 years experience, and A1 are the largest independent client of VELUX products. This type of conversion is generally very cost effective.

A Velux loft conversion requires considerably less construction work than a dormer or other types of conversion.  You can add an extra bedroom, living room or office cheaply and quickly – and start enjoying your new conversion within weeks.
