A Mansard loft conversion involves a flat roof with the back wall sloping inwards at a slight angle. This can accommodate Velux windows, small dormer windows and French doors. The style is named after the 17th century French architect, Francois Mansart.
A dormer loft conversion is an extension to the existing roof creating additional floor space and headroom. This is the most popular type of conversion as it creates the most space and can accommodate two rooms. Dormers can be place to the rear or the side of your house and can often be constructed without the need for planning permission.
A Velux or rooflight conversions is the simplest and most cost effective solution as it does not change the existing shape of your property. This also means you will not normally need planning permission. This type of conversion will enable you to start enjoying your new space in a matter of weeks.
