Isleworth

Isleworth is a small town with Saxon origins, located within the London Borough of Hounslow in West London, England. It is discovered to the east of the town of Hounslow and west of the River Thames and its tributary, the River Crane. The town's original settlement area, beside the River Thames, is pertained to as 'Old Isleworth'. The north-west corner of the town, linking on to Osterley and Lampton, is called 'Spring Grove'. Though Isleworth originally had a Thames frontage of around one mile, excluding that of the Syon estate, a borough limit realignment in 1994 lowered this to half a mile in order to increase land in the district of St. Margarets, Twickenham. Isleworth featured a significant range of artisan and white collar residential progression throughout the town, at the cost of numerous market gardens in the beginning of the 20th century. This period also experienced the building of a number of brand-new factories and offices. Such a quick spread of building changed the nature of Isleworth's design, transforming the town from an agrarian economy to an urban one. Because of many buildings avoiding being targeted in the Blitz, Isleworth contains numerous Grade II * listed buildings. The majority of these originate from the period of considerable mansion-building happening in the 18th and 19th centuries, thanks to the attraction of the rural, waterside beauty. There is a public library, a public leisure centre with a pool and gymnasium, four entertainment grounds and a town hall for the 20500 occupants to check out, along with plenty of opportunities to go shopping at nationwide and independent shops. For all your home upgrades, make certain to make use of trusted specialists in Isleworth to make certain of quality.

FAQs

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.

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.

Will I need planning permission to convert my loft?

Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.
