FAQs

what is a dormer loft conversion?

A dormer loft conversion is a type of loft conversion that’s built making use of a roof’s existing slope. In other words, it’s an existing roof’s extension which is constructed in such a way that allows for an additional floor as well as head room especially suitable for lofts lacking good amount of usable space. The dormer loft conversion is simply an addition to the existing roof looking much like a box-like build constructed onto a pitched roof as it creates walls that are vertical to the slope while also being 90 degrees to the floor.

This type of loft conversion is the most common amongst homeowners in the UK mainly because it represents a cost effective means through which you can add an additional usable space to your home or property. The structure extends for the slope of the existing roof and can easily be altered to suit various tastes or styles. Furthermore, if you’re looking for a type of loft conversion that aids to foster reduced disruption to work, then dormer loft conversion is also your best bet. This is due to the fact that the structure is built from a scaffolding made outside a home.

There are different types of dormer loft conversion and the one which will best suit your property will depend on the property type, be it detached, semi detached or terraced as well as the existing roof shape and size. The dormer loft conversion is a popular choice for a lot of homeowners for a variety of reasons. Let’s have a look!

✓ It’s very cost effective

✓ The dormer loft conversion does not require planning permission so far it complies with certain conditions and limitations

✓ It adds an extra headspace as well as floor space.

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.

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
