Caernarfon

Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of roughly 9,615. It is positioned on the A487 road, on the eastern shore of the Menai Strait, opposite the Isle of Anglesey. Bangor is 8.6 miles (13.8 km) to the north east, while Snowdonia borders Caernarfon towards the east and south-east. Carnarvon and Caernarvon are Anglicised versions of the name that became old fashioned in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are close by. Rich natural resources close to the Menai Straits enabled human habitation in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the location throughout the period generally known as Roman Britain. The Roman fort Segontium was established around AD 80 to control the Ordovices throughout the Roman conquest of Britain. The Romans controlled the region until Roman rule ended in Britain in 382, after which Caernarfon became a part of the Kingdom of Gwynedd. During the late eleventh century, William the Conqueror ordered the construction of a motte-and-bailey castle at Caernarfon as a part of the Norman invasion of Wales. He was unsuccessful, and Wales remained independent till around 1283. During the 13th century, Llywelyn ap Gruffudd, ruler of Gwynedd, refused to pay homage to Edward I of England, which led to the English conquest of Gwynedd. This was followed by the construction of Caernarfon Castle, among the biggest and most imposing fortifications constructed by the English in Wales. The city has come to be a significant tourist centre and seat of Gwynedd Council, with a bustling harbour and marina. Caernarfon has expanded beyond its medieval walls and experienced heavy suburbanisation. Its population consists of the largest percentage of Welsh-speaking citizens anywhere in Wales. The castle and town walls are part of a World Heritage Site described as the Castles and Town Walls of King Edward in Gwynedd. For all of your property improvement jobs, be sure that you employ reliable specialists in Caernarfon to ensure you get the top quality service at a great price.

FAQs

are house extensions worth it?

Often referred to by many as the holy grail of home improvements, house extension comes with a wide range of benefits which makes it easy to see why the extension could be a great uptick in the potential price of your property in terms of sales. So if you’re looking to build a new home extension but still not convinced about the project, we’re here to help you. Being fully aware any home construction work is usually a heavy investment, there’s a huge need to be set on your decision before scheduling the commencement of any work. So are house extensions worth it? Below are some of the top benefits offered by house extensions to help you decide if it’s the most suitable route for you.

• Add To Your Home’s Value

Building an home extension is a great way to add value to your home before selling. Increasing the living space of your home is an incredible appeal to many buyers which significantly increases your property’s total value. However, you must ensure that the extension is impressively designed using top quality materials in order to generate more value.

• Good Alternative To House Moving

The most common reason for moving is usually due to a lack of sufficient space, but with house prices steadily on the increase a cost effective alternative is highly sought after. This alternative is house extension which creates more space for the household to spread out and have more privacy.

• You May Not Require A Planning Permission

You can extend your house and still not need to apply for a planning permission. To achieve this, simply comply with the laid down rules set under the permitted development rights.

• Extra Living Space

If you fill you’re starting to outgrow your existing structure and do not buy into the idea of moving, then your best bet might just be to extend your home.

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.

Do I need my neighbours’ permission for an extension?

Well the reality is, sometimes, neighbours just don’t get along. With several individuals living in close proximity, it’s little surprise they tend to get on one another’s nerves from time to time. However, there’s a difference between having a tiff and being able to transform your house the way you want without having to obtain your neighbour’s approval.

The short and simple answer to this question is, not necessarily. However, you must first educate yourself by thinking about your extension and how it affects the houses around you. We’d strongly recommend you talk proposals through with your neighbour so as to avoid possible conflicts later. There are a number of reasons why your neighbour can protest to your new home extension plans. Let’s take a look!

 

  • In the event whereby your new extension is blocking their view or providing an unwanted shade on their property. Here, they have a legitimate reason to protest as no one would want their once sunny garden suddenly covered or plummet into shade.
  • In the event where it leads to a loss of privacy. For instance, if your new extension possesses a window which overlooks the neighbour’s property in any way. This is likely to be taken as an invasion of privacy and that has a little to no chance of being a welcomed idea.
  • If it’s a major project and going to take a lot of weeks before completion. The noise generated, especially when your neighbours are enjoying your summer holidays or weekends, can make their gardens not as relaxing as it used to be.
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.
