Types Of Loft Conversions

A London loft conversion is the ideal way to make maximum use of the space in your London home. There are four basic types of Loft conversions, depending upon the intended use and the design of the roof on the house to be modified.

Rooflight Conversions

velux loftRooflight Conversions are often called Velux conversions as this is the name of the leading manufacturer of this type of window.

These windows are fitted flush with the roof and therefore do not require any roof restructuring. In this way there is normally no need for planning permission; making this style of conversion the most cost-effective. However homeowners are advised to check with the planning department in their area for building regulations and the necessity of planning permissions.

The windows being installed at the angle of the roof provides a great deal of natural light, but may require blinds or tinted coverings in summer sunlight.

Dormer Conversions

dormer loft conversionDormer conversions involve extending the existing roof line, to provide more interior space and/or headroom. The Dormer will provide vertical walls and horizontal ceilings inside the loft, as opposed to the slanted internal sides of the existing roof.

This type of Loft conversion will require planning permission; some towns will insist these are only done on the front of the house, others only permit them at the rear, and in some areas dormers may not be permitted at all. The local area planning department will provide all the necessary information. Professional builders or loft conversion companies will know about the laws in their area, and should take care of all the legal paperwork for you.

Mansard Conversions

The Mansard roof is named after its inventor; Francois Mansart, a French architect in the 17th century. This is the least common type of loft conversion, as it maximises space and is by far the most expensive undertaking. This conversion will require total replacement of the existing roof, whereby the sloping roof becomes a box shape with a flat top and vertical walls: in this instance planning permission will definitely be required and not always granted.

Hip To Gable Conversions

hip to gable loft conversionHip to Gable conversions involve the reshaping of a roof at the sides. A hip roof slopes at each side as well as front and back, and this conversion will follow the side wall of the house up to a pointed top, level with the ridgeline, and the gap filled with new roofing. The new roof will then have Velux or Dormer Windows installed. The reshaping of the building means that planning permission will be required.

London loft conversion or construction companies will need to know the type of roof you have, the style of conversion you require, and your budget. They will then advise you on which of the different types of loft conversion is more suited to your needs.

The best idea would be to find some different designs and plans and take into consideration the building regulations in your area and if planning permissions are necessary. From there you can make an informed choice on the best options for your particular requirements.
