FAQs

an every house have a loft conversion?

If you’re having issues with the amount of space in your home and need an extra space without affecting your garden, loft conversion comes to mind. Not only is it a great solution to creating more living space within a home, but it’s also one of the most budget-friendly solutions you can count on to expand your space by thinking upwards rather than sideways. So if you’re thinking about converting your loft, one thing that almost immediately comes to mind is whether or not your house is suitable for loft conversion.

To answer the question of whether every house can have a loft conversion is a very simple one. Generally, not every house is suitable for loft conversion. This is due to the fact that each and every loft space - from the stairways below and floors to the rafters and the roof up above, is unique. Therefore, the best way to really figure out whether or not a house’s loft offers the potential for conversion is to get in touch with a loft specialist.

So what can make a house not suitable for a loft conversion? Let’s take a closer look!

✓ A house will not be suitable for a loft conversion if the height of the ceiling happens to be too low and it’ll not be possible to have it raised.

✓ If you do not own own the freehold to the loft space, you won’t be able to convert the loft. Surprisingly, this happens to be a common issue in London.

✓ You will not be able to convert your loft if you reside in a conservation area or in a listed building. But you can identify a design solution that’ll still comply with the conservation rules and keep planners happy.

Can my loft be converted?

Many types of loft are suitable for a loft conversion. In general, you will need at least 2.3 metres of headroom in your existing loft. This is to make sure there is enough headroom after the conversion. Speak to a conversion specialist about the probability and possibility of doing this in your house.

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 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
