Welwyn

Welwyn (population 8,425) is a town and civil parish in Hertfordshire, England. The parish additionally includes the villages of Digswell and Oaklands. It is often called Old Welwyn to differentiate it from the much newer negotiation of Welwyn Garden City, regarding a mile to the south, though some residents dislike the recommendation of inferiority or irrelevance that has a tendency to be suggested by the name "Old" and prefer Welwyn Village. When saying where they live, citizens will often be asked, 'Welwyn or Welwyn Garden City?', as the latter's title is commonly shortened to merely Welwyn. To stay clear of complication, there were plans to change Welwyn's name to 'Welwyn Minster' in 1990 yet this consulted with neighborhood resistance and also the concept was abandoned. The name is derived from Old English welig meaning "willow", referring to the trees that nestle on the financial institutions of the River Mimram as it streams with the town. The name itself is a development from weligun, the dative form of the word, and so is extra precisely equated as "at the willows", unlike neighboring Willian which is likely to suggest just "the willows". Through having its name stemmed from welig instead of sealh (the much more generally mentioned Old English word for willow), Welwyn is perhaps cognate with Heligan in Cornwall whose name is stemmed from helygen, the Cornish word for willow that shares an origin with welig. The neighboring modern town of Digswell (around Welwyn North train station) was initially called 'High Welwyn' when initial established at the beginning of the 20th century.

FAQs

an every house have a loft conversion?

If you’re having issues with the amount of space in your home and need an extra space without affecting your garden, loft conversion comes to mind. Not only is it a great solution to creating more living space within a home, but it’s also one of the most budget-friendly solutions you can count on to expand your space by thinking upwards rather than sideways. So if you’re thinking about converting your loft, one thing that almost immediately comes to mind is whether or not your house is suitable for loft conversion.

To answer the question of whether every house can have a loft conversion is a very simple one. Generally, not every house is suitable for loft conversion. This is due to the fact that each and every loft space - from the stairways below and floors to the rafters and the roof up above, is unique. Therefore, the best way to really figure out whether or not a house’s loft offers the potential for conversion is to get in touch with a loft specialist.

So what can make a house not suitable for a loft conversion? Let’s take a closer look!

✓ A house will not be suitable for a loft conversion if the height of the ceiling happens to be too low and it’ll not be possible to have it raised.

✓ If you do not own own the freehold to the loft space, you won’t be able to convert the loft. Surprisingly, this happens to be a common issue in London.

✓ You will not be able to convert your loft if you reside in a conservation area or in a listed building. But you can identify a design solution that’ll still comply with the conservation rules and keep planners happy.

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.

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.

Will I need planning permission to convert my loft?

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.
