Caernarfon

Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of roughly 9,615. It is on the A487 road, around the eastern shore of the Menai Strait, opposite the Isle of Anglesey. The city of Bangor is 8.6 miles (13.8 km) to the north east, while Snowdonia borders Caernarfon to the east and south-east. Carnarvon and Caernarvon are English versions of the name which were superseded in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are nearby. Abundant natural resources close to the Menai Straits enabled human habitation in prehistoric Britain. The Ordovices, a Celtic tribe, settles in the area through the period known as Roman Britain. The Roman fort Segontium was created around AD 80 to control the Ordovices throughout the Roman conquest of Britain. The Romans occupied the area till Roman rule ended in Britain in 382, and Caernarfon became part of the Kingdom of Gwynedd. In the late eleventh century, William the Conqueror ordered the building of a motte-and-bailey castle at Caernarfon as part of the Norman invasion of Wales. He was unsuccessful, and Wales remained independent till about 1283. During the thirteenth century, Llywelyn ap Gruffudd, ruler of Gwynedd, refused to pay homage to Edward I of England, prompting the English conquest of Gwynedd. This was followed by the construction of Caernarfon Castle, one of the largest and most imposing fortifications constructed by the English in Wales. The city has become a major tourist centre and seat of Gwynedd Council, with a busy harbour and marina. Caernarfon has expanded beyond its medieval walls and experienced heavy suburbanisation. Its population contains the largest percentage of Welsh-speaking citizens anywhere in Wales. The castle and town walls are a part of a World Heritage Site described as the Castles and Town Walls of King Edward in Gwynedd.

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.

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.

what is a dormer loft conversion?

A dormer loft conversion is a type of loft conversion that’s built making use of a roof’s existing slope. In other words, it’s an existing roof’s extension which is constructed in such a way that allows for an additional floor as well as head room especially suitable for lofts lacking good amount of usable space. The dormer loft conversion is simply an addition to the existing roof looking much like a box-like build constructed onto a pitched roof as it creates walls that are vertical to the slope while also being 90 degrees to the floor.

This type of loft conversion is the most common amongst homeowners in the UK mainly because it represents a cost effective means through which you can add an additional usable space to your home or property. The structure extends for the slope of the existing roof and can easily be altered to suit various tastes or styles. Furthermore, if you’re looking for a type of loft conversion that aids to foster reduced disruption to work, then dormer loft conversion is also your best bet. This is due to the fact that the structure is built from a scaffolding made outside a home.

There are different types of dormer loft conversion and the one which will best suit your property will depend on the property type, be it detached, semi detached or terraced as well as the existing roof shape and size. The dormer loft conversion is a popular choice for a lot of homeowners for a variety of reasons. Let’s have a look!

✓ It’s very cost effective

✓ The dormer loft conversion does not require planning permission so far it complies with certain conditions and limitations

✓ It adds an extra headspace as well as floor space.

How long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.
