Are you thinking about a loft space conversion as a way to open up space in the house to avoid the requirement to move? Then use our totally free and easy service to compare prices and find the top cost for the work you need carried out.
Loft conversions are proving to be more popular then ever in the UK. In most properties the attic makes up unused space which will be put to better use. Converting can turn the area into a bedroom, bathroom, playroom or perhaps ensuite bedroom.
In fact there's plenty of potential to converting your loft, such as the extra value for the home which may be as much as 20%. Loft space conversions are also advised over a house extension as the infrastructure is already in place. Plus, you won't be taking away any garden space.
If the loft conversion would benefit your house and you're looking for extra space, compare and contrast quotes from reputable companies in Carmarthen and get the best deal for the work you need completed.

Carmarthen is the county town and community of Carmarthenshire in Wales. Situated on the River Towy, it is eight miles north of its mouth at Carmarthen Bay. According to the 2011 Census, the town includes a permanent population of about 14185, which demonstrates a slight population decrease because the 15854 residents recorded in the 2001 Census. It's claimed that Carmarthen is the oldest town in Wales, but the two settlements of Old Carmarthen and New Carmarthen were only united into a single borough in 1546. Nonetheless, it was undeniably the most populated borough in Wales over the course of the 16th century and continued to be so until the 18th century. Population only began to stagnate by the middle of the 19th century when towns with more dynamic economic centres started to develop in the South Wales coalfield, which attracted considerable numbers of people for work. The town is presently the location for a lot of institutions, which includes the administrative centre of Dyfed-Powys Police, the Carmarthen campus of the University of Wales, Trinity Saint David and Glangwili General Hospital. Various landmarks can also be located in Carmarthen. Even though little remains of the original castle at Carmarthen, Carmarthen Castle is a well-known tourist attraction. The old Gatehouse continues to dominate Nott Square, and also the motte is accessible to the public. Within the old walls of Castle House, guests can find a museum and also a Tourist Information Centre. The town's parish church, St. Peter's Church, is known to be the largest parish church inside the Diocese of St. David's, as well as possessing the longest nave, which is 60 metres from the west porch to east window.

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?
Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.
✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.
✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.
✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.
✓ Hip To Gable Loft Conversion - This usually starts from £50,000.
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.
Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.
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.
