Calne

Calne is a town and civil parish in Wiltshire, southwestern England, at the north western extremity of the North Wessex Downs hill range. A marked Area of Outstanding Natural Beauty, Calne is situated on a little river, the Marden, that rises 2 miles (3 kilometres) away in the Wessex Downs, and it is the only town on that river. As per the 2011 Census, Calne boasted a resident population of roughly 17,274 inhabitants. Since the late 1990s, Calne grew dramatically in contrast to most other towns in the South West area. The Lansdowne Park property development, finalised in late 2008, has considerably enhanced the physical size of the town, producing a totally modern north-western suburban area. This incorporates a new primary school, a medical centre and a modest shopping area containing a mixture of shops. This kind of redevelopment has brought in professional workers from historically more well off locations for instance, Bath, Bristol, Marlborough and even as far afield as the 'silicon valley' towns of central Berkshire. Remarkable buildings in the town include St Mary's Church, an array of houses on The Green, and the town hall. Of special note is Calne Library, opened by the Queen in 2001, which has won prizes for its groundbreaking style. Since the demolition of the Harris pork factory and the conclusion of the first phase of redevelopment regeneration in 2001, Calne has seen Cotswold stone, just like local limestone, being put to use in addition to smart red brickwork, previously saved for fine historic buildings. For all your home upgrades, make certain to make pick of vetted experts in Calne to be sure of a fantastic quality service at a great price.

FAQs

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.

how much value does an extension add to your house?

Are you interested in extending your home to create more living space? If yes, then you’d probably want to know how much value it can add to your property in order to compare the building costs to the potential value gain. Well, as long as you know what you’re doing, your house doesn’t necessarily have to be a money pit. So what are your options when talking about home extensions and what’s the associated value to be gained?

• Bathroom Extensions

Although you should have it in mind that bathroom extensions isn’t usually that cheap, but once done, it can increase the value of a standard UK house within the range of £12,000 to £15,000. Meanwhile the finishing cost of a bathroom can range from £2,500 to £7,000.

• Single or Double Storey Extensions

Single storey extensions are always huge when it comes to increasing the value of your home - giving about 4 to 7 percent increase. If it goes that far, then literally nothing beats a full spectrum, double storey extension which can give up to 11 percent increase in the value of a property - equalling about a whooping £33,000 for a standard home in the UK.

• Conservatory Extension

With conservatories becoming more and more popular in the UK due to the weather conditions, several buyers are now including it’s availability as part of the criteria for purchasing a house. Wonder why? This is simply because everyone wants to enjoy their garden all throughout the year. As a result of this high demand, adding this type of extension to your house can go a long way to increase it’s value. However, it’s very important to incorporate high quality materials during construction. With glass conservatories offering, on the average, up to £5,000 increase in value, the cheaper PVC alternative offers much less value and can also deter potential buyers.

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.

Can an extension add value to my home?

Yes. Most extensions will add substantial value to your home, and you may find that the extension adds more value than it cost. However, it’s important to be sure that the home remains balanced. Extending your garage and leaving your property with no parking spaces, for example, may impact your ability to sell.
