Penarth

Penarth is a town in the Vale of Glamorgan, Wales. It is set 5.2 miles south west from the city centre of the Welsh capital city of Cardiff and it is on the north bank of the Severn Estuary at the southern end of Cardiff Bay. With a population of 22083, it is the 2nd largest town in the Vale of Glamorgan, coming second to the administrative centre of Barry, and Penarth is the seaside resort with the most wealth in the Cardiff Urban Area. The town was a remarkably popular vacation spot during most of the Victorian period, typically described as 'The Garden by the Sea', with the highest percentage of visitors travelling from the Midlands and the West County, along with day trippers from the South Wales valleys who took a trip by train. Regardless of the fact that the town continues to be a popular holiday spot in the summer, with its traditional seafront predominately intact, the amount of visitors is much lower than was common in between the Victorian period and the middle of the 20th century, most notably once reasonably priced plan holidays overseas appeared. Regardless, the town maintains a large retired population, representing over 25 percent of locals, and it is largely a dormitory town for Cardiff commuters. However, landmarks and tourist attractions continue to preserve a steady flow of visitors to the town all throughout the year. Cosmeston Lakes County Park has been a popular choice since its establishment in the 1970s, which has acres of walks and woodlands on the heath. Cosmeston Mediaeval Village, which presents historical re-enactments, enables visitors to check out a reconstruction of a historic village and has been referred to as the very best of its type in Britain. For all of your house upgrades, make sure to make use of reputable professionals in Penarth to make certain of quality.

FAQs

how big can my house extension be?

The holy grail of home extensions is basically the need for additional space for living as well as leisure. However, before commencing your home extension project, you’d probably want to know just how big your new building can be. In this article, you’ll find the answer to this question which is also frequently asked by many other home or property owners in the UK.

Besides your budget, there are two other major influencing factors that can determine just how much extra room that can be added. These factors include whether you wish to carry out the extension project under Permitted Development rights which is usually for a smaller project or you’d prefer to opt for a larger project which is covered by Planning Permission.

Apart from the limitations in the size of an extension under Permitted Development, the extensions are also a lot more affordable and consumes less time when compared to the extensions under planning permission. So what exactly is the size limit for an extension under Permitted Development and the ones under Planning Permission?

For a single storey extension, the maximum size that can be constructed without having to submit an application for Planning Permission includes:

• An extension should have a maximum length of 6m, if you reside in a terraced home or a semi-detached property.

• Extensions for detached properties can have a maximum length of 8m.

• The extension built must not go beyond half your garden’s area.

• The extension should have a maximum height of 4 metres, but in the event whereby the extension is situated within 2 metres of the boundary of your property, it should not exceed a height of 3 metres.

• The extension should not be higher than the highest part of the existing house’s roof.

Can I extend the front of my house?

When it comes to extending a home, the rear of the house often comes to mind a lot more than the front. However, this doesn’t mean that you can’t extend the front of your house. This can be done either as part of a renovation project whereby the entire house is incorporated or it can also be done in isolation. It’s possible to extend the front of your house without the need to apply for a planning permission, however, there are a bunch of limitations you’d have to comply with if you wish to carry out with such a project. Sometimes, this may imply that extending to the front of your home is more tedious and tasking than extending your home’s rear. So exactly how far can you extend the front of your home without planning permission?

 

The short and simple answer to this question is 2 metres square area with a height not more than 3 metres. Generally, you do not need a planning permission to build a front porch as long as its area doesn’t go beyond 2 square metres from a public road or walkway. Also, a tiled or slated roof can be as much as 4 metres but other roofs must not go beyond 3 metres in height. If you want to extend the front of your home beyond the restrictions specified, then you’ll have to apply for a planning permission.

 

Extending the front of home can be quite costly, but this can be controlled by not building to the extension to the highest specification, not including an extension on kitchens or bathrooms and more.
