Loft Conversion types and cost:
Loft conversions fall into one of four basic types, which type you decide to use for your loft conversion will depend on many factors such as the design of your existing roof, your budget, planning restrictions and your own personal preferences.
"Velux" Loft Conversion
With this type of construction the roof line is unaltered and a room is simply created in your existing loft space. 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.
Usage: Play room, Bedroom, Office, Storage.
Typical cost for this type of loft conversion starts from Â£15,000 for typical Victorian 2 storey mid terrace house to create single room.
Dormer Loft Conversion
A dormer is a loft extension to the existing roof, allowing for additional floor space and headroom within the loft conversion. A dormer extension will normally not span the whole width of the current roof, but will only take up a part of it. This option is often used for bedrooms in suit and makes a lot more light available in the room.
There are different types of dormer:
- Gable fronted dormer - these are sometimes called a dog house dormer
- Hipped roof dormer - a dormer with a hipped roof
- Flat roof dormer - you guessed it - it has a flat roof!
- Shed dormer - a single planed roof that is pitched at a shallower abgle to the main roof
Mansard Loft Conversion
This type of loft extension is generally designed within the inner London areas, where clients are following the Mansard trend of similar conversions within their locality. Sometimes it is required type of construction in conservation areas.
The mansard conversion is slightly different to the dormer conversion because instead of adding to the existing roof space, rear of the roof taken off and rebuild altogether. A mansard conversion also has a flat roof but the rear face of it slopes back by about 70Â°. A mansard loft conversion will almost certainly require planning permission.
Hip To Gable Loft Conversion
A hip to gable conversion involves extending loft space to the side of the roof. The gable wall is built up to the ridge line and a new section of roof is built to fill in the gap. As a general rule, houses with hip roofs tend to not have enough internal volume for a conversion to be practical so a hip to gable conversion is the best solution.
Planning permission usually not required.
