FAQs

What kinds of loft conversion are there?

There’s a huge range of different types of loft conversions. The most common are dormer and skylight or Velux conversions. There are also hip to gable and mansard conversions. The type of loft conversion that’s most suitable for your property will depend on the style of roof and the size of your loft.

how much is a dormer loft conversion?

Are you considering a dormer loft conversion for your home? If yes, then you’d probably want to know how much it costs. Unfortunately, due to the several variables and influencing factors, a precise answer can not be provided for all dormer loft conversions. In this article we’ll give you a vague idea of the general cost so you can set a more realistic budget and start planning.

There are three main types of loft conversion which includes the Velux, Dormer, and Mansard. Out of the three types, the dormer happens to be the most common type and possesses a small flat roofed extension with a window. The dormer loft conversion will usually cost within the range of £25,000 to £30,000.

The price for a smaller dormer loft conversion, mid range dormer loft conversion and large scale dormer loft conversion will be at £2,000 to £7,000, £10,000 to £30,000 and £40,000 to £60,000 respectively. However, you should take note that the prices given are all based on varying influencing factors such as the type of installation that is selected, the type of the rood, en suite conversion as well as other customization. Changes in price can be as a result of the materials required and the extra time per labour that’s needed to complete this home improvement project by the tradesmen employed.

Furthermore, a dormer loft conversion average cost will also depend on the type of dormer you opt for. Here is a list of the most common applications:

✓ Blind dormer loft conversion - £3,200 to £4,400

✓ Recessed dormer - £1,300 to £1,850

✓ Barrel roof dormer - £3,000 to £4,600

✓ Gable dormer - £5,500 to £7,500

✓ Hipped roof dormer - £5,600 to £6,660

✓ Pedimented dormer - £12,700 to £23,100

✓ Flat roof dormer loft conversion - £13,800 to £21,600

how disruptive is a loft conversion?

Asides the questions relating to planning permission of a loft conversion as well as the total cost of completing a loft conversion project, this is perhaps the most common question on the loft conversion subject matter. Before making an investment decision, many homeowners will want to know just how disruptive a loft conversion is. Well, we’ve all heard the several horror stories when loft conversion builder with dirty boots tramples all over the fresh and just-acquired shag pile or the noise of the construction loud enough to annoy neighbours from four blocks away or an obvious shortage of teabags, sugar and lots more. Good news is, the disruption of loft conversion is not as bad as people make out. Let’s have a look at how it works!

Just like all other major building projects, a loft conversion is disruptive to your property. However, no two loft conversions are the same, therefore some are certain to be more drastic and invasive than others. In the long run, the project is worth the stress and inconveniences caused and in most cases, it’s usually a very good investment.

Normally, an average loft conversion is expected to last for about 9 to 12 weeks (depending on the complexity of the loft conversion project some might take longer). Some of the factors that affects the duration of a project includes the type of the loft, the design of the loft as well as the style of the property.

Generally, a loft conversion is a lot less disruptive than say completely moving a home. It all has to do with how you’re able to deal with it as a person. And besides, the effect it’s going to have to a large extent depends on the company you hire. A good company will always look to ensure to keep disruptions to a minimal when carrying out the loft conversion project.

do you need planning permission for a loft conversion?

Typically, loft conversions do not require planning permission except in certain situations. They’re usually covered under what’s known as Permitted Development. Certain building works like loft conversion, rear extension and conservatories are granted planning permission by local authorities. Permitted Development, however, gives you a free range to improve your home without having any issues from the councils or regulations. Before your planned loft conversion can be covered under Permitted Development, there are some certain criteria that must be met. This criteria includes the following:

✓ The extension must not go beyond the existing slope of the roof at the front of the house.

✓ The loft space converted must not go beyond 40 cubic metres in a terraced house.

✓ The roof’s height must not be increased by the extension.

✓ The loft space converted must not reach beyond 50 cubic metres in a detached or semi detached house.

✓ The plan for the extension mustn’t involve structures like balconies, verandas or anything other structures of this nature.

✓ The roof extension should be positioned as far back as possible or at least 20cm from the existing eaves.

✓ The side that faces the window openings should be at least 1.7m beyond the floor and the windows should also be obscured.

✓ The roof extension must not overhang the existing roof or wall of the house.

✓ The materials that are to be used must be similar or the same to the materials that has already been used on the house’s exterior.

However, you should bear in mind that there are some properties that are exempt from Permitted Development. Examples of these type of properties include conservation areas, Areas Of Outstanding Natural Beauty and World Heritage sites. Permitted Development does not also provide coverage for listed buildings.
