Caldicot

Caldicot is a small town and community within Monmouthshire, southeast Wales. The name 'Caldicot' is usually thought to derive from the Old English phrase 'calde cot' which means 'cold hut'. A cold hut is an exposed shelter made use of by either humans or animals. According to population estimates collected in 2014, the town features a resident population of approximately 11,424. Among the oldest buildings in Caldicot, Llanthony Secunda Manor was constructed about 1120 as a grange for monks from Llanthony Secunda Priory in Gloucester. By the middle of the nineteenth century, Caldicot became characterised as a little farming village. Nevertheless, the introduction of the South Wales Railway brought London and Cardiff within fairly easy reach, although Caldicot station wasn't opened until 1936. Due to the business which was attracted by the railway, Henry Hughes of Tintern opened a wireworks next to the railway in 1862, which was soon to turn out to be the village's primary employer and attracted many new workers. In 1880, it became a tinplate works for the canning business. A popular landmark in the town is Court House, which was the house of baker Henry Jones, the creator of self-raising flour, from 1864 until his death in 1891. He's buried in the churchyard. Caldicot is also most famously referred to as the location of Caldicot Castle and lake. The area has popular waymarked footpaths along the Caldicot Levels and the coastal path may be walked. Close by tourist attractions are Caerwent and Wentwood. To the north west, Dewstow House dates from about 1804. Substantial gardens and grottoes constructed after 1895 have been undergoing restoration since 2000 and are now open for the public.

FAQs

when do you need planning permission for a house extension?

If you’re planning on adding a house extension to your property, you’d probably be worried about whether or not your proposed extension would require a planing permission. Well, it may be relieving to know that not every house extension project would require a formal consent, and in fact, several extensions are covered by the permitted development rights. Not only can this save you a considerable amount of time especially at the project’s planning phase, but it’ll also save you money on the application fee. In the UK, single storey extensions to the house’s rear can be 3 metres deep for both semi detached houses and terraces or 8 metres deep for detached homes.

So how do you know when you’d require a planning permission for your home extension? Well, if your extension plan fits these criteria explained below, then your project is most likely going to be allowable as a permitted development.

• Extensions, which includes previous additions, must not go beyond half of the original house’s total surrounding land area.

• The main elevation, or side elevation where it fronts the highway, must not be extended forward.

• For single storeys, the rear additions must not extend more than the original house’s rear by more than 3 metres in both semi attached homes and terraces (4 metres for detached houses).

• Extensions to the side must be a single storey with a height not exceeding 4 metres and not going beyond 50% of the original house’s width.

• Extensions hat within 2 metres of a boundary should have a eaves height not more than 3 metres.

• Multi storey addition must not extend beyond the original house’s rear wall by a maximum of 3 metres or 7 metres of the boundary opposite the rear wall.

• Permitted development rights do not apply in listed buildings or designated areas.

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.

how to finance a house extension?

Do you want to beautify and increase the value of your home? If yes, a refurb and house extension is definitely a great option to consider. Depending on your home extension project, the value that’ll be added to your home’s resale value varies. However, the cost of completing a house extension project can be huge, so you just might want to consider your financing options. Fortunately, there are various options through which your house extension project can be funded with each having its own pros and cons. Your specific circumstances will determine the one that’s going to work best for you, so let’s take a look at some of the best options to help you fund your project.

• Home Remortgaging

The process whereby a mortgage is transferred from one provider to the other is known as remortgaging. This is usually done to generate funds for a project by entering a more lengthy repayment term commitment when switching. If you want to raise your funds in a quick manner, this process works best.

• Savings

This is a good reason to cultivate a good saving habits. If you’ve been able to save up some mega bucks then you’d probably won’t have to borrow money to finance your house extension.

• Unsecured Loans

If you do not buy into the idea of borrowing more against your property, you may just be able to apply for an unsecured loan especially if you have a good credit record. A secured loan makes use of collaterals like a car or house to serve as a cover for the lender, meanwhile an unsecured loan is based mainly on the credit managing history of the borrower.

• Credit Card

There are some great benefits that comes with financing your small or medium scale extension project with your credit card. Not only does it offer some real lifeline if problems arise during the project, but you can also avoid paying excessive interest on the investment by ensuring your deal has a 0% introductory rate.

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.
