Harrow

Among London's most greatly inhabited boroughs holds about 239,000 and is set towards the north east of the capital. The town of Harrow was developed in 1934, becoming a borough in 1954. The borough encompasses a contrast in affluence; even though there are high-end regions such as Harrow-on-the-Hill and Pinner, a 2011 report shows 7,000 children are in poverty. Don't spend more than you need to for your household improvements and get the ideal price from vetted installers.

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.

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 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.

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.
