Isleworth

Isleworth is a town with Saxon origins, situated within the London Borough of Hounslow in West London, England. It is found 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 known as 'Old Isleworth'. The north-west corner of the town, linking on to Osterley and Lampton, is referred to as 'Spring Grove'. Though Isleworth originally had a Thames frontage of around one mile, omitting that of the Syon estate, a borough limit adjustment in 1994 reduced this to half a mile so as to increase land in the district of St. Margarets, Twickenham. Isleworth featured a substantial number of artisan and white collar domestic growth throughout the town, at the expense of various market gardens in the beginning of the 20th century. This period also experienced the building of a number of new factories and offices. Such a fast spread of building transformed the nature of Isleworth's design, changing the town from an agrarian economy to an urban one. Due to many buildings staying clear of being targeted in the Blitz, Isleworth contains numerous Grade II * listed structures. The majority of these originate from the period of significant mansion-building occurring in the 18th and 19th centuries, thanks to the attraction of the rural, waterside beauty. There is a town library, a public leisure centre with a swimming pool and gymnasium, four entertainment grounds and a town hall for the 20500 inhabitants to visit, along with plenty of opportunities to shop at nationwide and independent stores. For all of your home upgrades, make sure to make use of reputable contractors in Isleworth to make certain of quality.

FAQs

Should I use concrete or timber footings?

For 2 metre solid fences it’s recommended to use concrete posts to support each panel. For smaller 1 metre fences or for picket fences with gaps between each timber piece you can use timber posts. A fencing contractor will be able to advise you on the best materials from the length and requirements of a new fence.

What types of extension are there?

There are many different types of extension. For example, you could install an orangery, flat or pitched roof extension, over-structure extension, single or double storey extension or a glass box extension. Which one of these is most suitable will depend on your existing property.

how long do house extensions take?

If you’re about to start your house extension project and wondering how long it’ll take to complete, you’re not alone! This is one of the most common questions that’s asked by homeowners in the UK and across the globe. However, there’s no single precise answer for this as there are multiple factors that’ll affect the length of time it’ll take to complete your home extension. These factors include the size of the construction work as well as whether you’re planning to live in the house after completion or otherwise.

For a single extension, the length of time it’ll take to complete the home extension is normally up to 3 months. So let’s break this down:

As you would have expected, the first step to be taken is the preparation of the site. You start by digging out the footing and preparing the foundation which should take about 2 weeks. This is then followed by the damp course installation as well as the fitting of any drains needed around the extension which will also take a further 2 weeks.

The 5th week will be for the construction of the external walls as well as putting the blockwork in place for the provision of the cavity wall insulation. A further 2 weeks after this, will be dedicated to the installation of the roof structure and the internal walls.

It’s at this junction that you’ll call on your weather proof installer to fit in your uPVC windows and doors. Once done, the gas fitters and electricians will have to be on site to connect power to your new extension building. Subsequently, this will be followed by internal wall plastering as well as breaking through your main house. Once the plaster is dried, decorations completed and all the required furniture and units installed, the extension is ready for use.

Can I extend the front of my house?

When it comes to extending a home, the rear of the house often comes to mind a lot more than the front. However, this doesn’t mean that you can’t extend the front of your house. This can be done either as part of a renovation project whereby the entire house is incorporated or it can also be done in isolation. It’s possible to extend the front of your house without the need to apply for a planning permission, however, there are a bunch of limitations you’d have to comply with if you wish to carry out with such a project. Sometimes, this may imply that extending to the front of your home is more tedious and tasking than extending your home’s rear. So exactly how far can you extend the front of your home without planning permission?

 

The short and simple answer to this question is 2 metres square area with a height not more than 3 metres. Generally, you do not need a planning permission to build a front porch as long as its area doesn’t go beyond 2 square metres from a public road or walkway. Also, a tiled or slated roof can be as much as 4 metres but other roofs must not go beyond 3 metres in height. If you want to extend the front of your home beyond the restrictions specified, then you’ll have to apply for a planning permission.

 

Extending the front of home can be quite costly, but this can be controlled by not building to the extension to the highest specification, not including an extension on kitchens or bathrooms and more.
