Types of Loft Conversions for West Wimbledon


1. Dormer Conversions SW20

A dormer is an extension to the existing roof, allowing for additional floor space and headroom within the loft conversion.

Dormers protrude from the roof slope, normally at the rear of the property and can be built in a variety of styles. Internally, a dormer will have a horizontal ceiling and vertical walls compared to the normal diagonal sides of a conversion. In lofts that have limited space or headroom a dormer will provide additional space that can make a conversion feasible.

Flat roof dormers tend to give the maximum amount of additional internal space although they do not look as attractive from outside the property. Gable fronted and hipped roof dormers look much more attractive but they often do not give as much internal space and will cost more to build due the extra complexity.


2. Mansard Conversions SW20

A Mansard roof has two slopes, the lower slope is close to vertical at 72 degrees and the top section of the roof is almost horizontal.

This style of roof is named after a 17th-century French architect Francois Mansart (1598-1666) who used this design of roof on many of his buildings. A Mansard roof has the advantage of maximising the available space within your loft.

Mansards are commonly built by raising the party/gable walls either side of your house to make the profile for the Mansard and then creating the timber frame. Although common on older properties, especially in cities like London, Mansards are not often seen in the suburbs. Flat roof dormers tend to be a more popular choice for the 'average' 3 bed semi or terrace house due to the reduced cost and simpler construction. A Mansard loft conversion will almost certainly require planning permission. Things definitely worth considering.

While this type of roof will give you the maximum amount of space in your loft conversion it does have a downside - as it involves replacing the entire roof the construction costs will be high. Therefore, it is quite unusual to see this type of conversion, unless the original roof was built in this style.


3. Velux Conversions SW20

Velux and roof light conversions are the same with Velux being a brand name. This type of conversion is generally very cost effective, is quick and simple and in most cases it does not require planning permission.

Roof light Velux windows are easy to install and normally only require one of the existing rafters to be trimmed out per window. The Velux windows are installed to fit flush with the line of the roof and leave the existing roof structure untouched. As they do not require extensive alterations to the roof this option helps keep the cost of the conversion down. As the loft is not extended beyond the original roof line planning permission is not normally required (you should still check with your local planning department before proceeding with any works).

A Velux type loft conversion works very well for lofts where there is a good amount of headroom or if there are constraints on planning, for example if you live in a conservation area. If headroom is going to be limited then either a dormer or mansard conversion may be a better option. Velux roof lights can be fitted quickly and easily meaning there is minimal disruption or delays due to bad weather.

As Velux windows are installed at the angle of the roof rather than vertically like a normal window they can let in a surprising amount of light. While this is great during the day and will give you a light and airy room it can become a problem at night or in the summer. Window blinds are available from various sources tailor made for Velux windows that perfectly fit into the window frame. You can even get blinds that have a thermal silver backing, great for retaining heat in the winter and keeping it out in the summer.
