As they provide the greatest headroom and usable floor area in a loft conversion project, dormer loft conversions are the most popular loft conversion design.
However, depending on the total size of the conversion, how you decorate the interior, and the number of windows you have, dormer conversions can be costly. You might expect to pay upwards of £5,000 if you already have a loft conversion and want to add a dormer, but this is largely dependent on the situation.
When to add a Dormer to your existing loft conversion
There are several advantages to adding a dormer to your loft conversion.A dormer may add elegance and charm to your house while also improving headroom and optimizing usable floor area. It can also turn a tight loft space into a full-height, light-filled room.
There are two possible circumstances for adding a Dormer to the existing loft conversion:
You have purchased a home that already has a roofline conversion and opt to renovate the loft space to make it larger and brighter, as well as maybe modify the interior use.
You decided that the loft conversion will be completed in two parts, either to spread the expense or because the current needs will be filled by a simpler roofline conversion. If you don’t want to put in kitchens or toilets, a typical Velux loft conversion costs roughly £15,000.
Whether to get planning permission to put in a dormer conversion
Converting a loft and/or installing a dormer window often comes within the UK’s “permitted development” guidelines, and so does not require planning approval. Permitted development comes with various restrictions and criteria.
The total size of the loft conversion; the upgrading may result in a greater conversion than the initial plan. Whether or not the property is on the National Register of Historic Places or is located in a conservation area. How much structural alteration is made to the present roof height and the distance between the roof plane and the dormer windows are also considered.
Not all dormer window conversions require planning permission, and we can advise you if one is required.
Different types of Dormer conversions
You can choose between a flat roof dormer, a shed dormer (slanted roof), a Dog-house dormer (two slanted roof side), and a hipped roof dormer (three slanted roof side).
