There are four main types of loft conversion found in UK homes. A loft conversion can be used as a guest bedroom, study or playroom, adding both floorspace and value to your property. Expect to spend between £20-45,000 and 4-8 weeks converting your empty roof space into a loft.
To decide what sort of conversion will suit you best, you’ll need to consider the shape and line of your existing roof, your budget and your permitted development rights. Working with a skilled architect can help you to understand how to draw the best plans for your home.
There are three basic types of structural alterations.
1. Dormer loft conversion
The most popular type of loft conversion is a simple flat roof dormer. This is a structural extension which projects vertically from the slope of the existing roof, creating a box shape. This loft extension generally requires no dramatic changes, and allows for the installation of conventional windows.
- Adds useful headroom in a cramped attic
- Leaves straight walls and flat ceilings
- Creates a large amount of additional internal space
- Good light and ventilation
- Inexpensive compared to other choices
- Suitable for most UK house styles
- Often falls under permitted development
- Not always the most aesthetically appealing choice
For a mid-terrace period property, an L-shaped dormer - which wraps around the side and rear of the property - is a popular adaptation.
You may also wish to consider a gabled dormer, which has a more traditional inverted "v" shaped roof. This might be a more visually pleasing choice for the front of your property. However, it tends to be a more expensive option, which also places limitations on headroom.
