Where is Harpenden Located? 

Harpenden town is a civil parish within the City and District of St Albans. In 2011, the population of the civil parish and built-up area was 30,240. The town's population is a mix of urban and rural, which reflects the varied socioeconomic status of the community. However, the town is home to many people of different backgrounds and income levels.

Located in Hertfordshire, Harpenden is a former agricultural village. Now it is an upmarket commuter town, boasting a village feel and community spirit. The town sits between the historic city of St Albans and the large town of Luton. Its name derives from the Latin "herpe dene", which means military road through a valley. The town is home to about 30,000 people, but still retains a quaint countryside feel.

Home extensions vs. loft conversions - what’s right for you?

When deciding whether to build an extension or a loft conversion, there are numerous aspects to consider. Both projects provide homeowners with the opportunity to add usable space to their houses without having to relocate — and each can add significant value if done well.

What adds more value - An extension or a loft conversion?

It's pretty challenging to estimate how much value an extension will bring to a home; the size and location of the expansion, as well as the sort of space it adds, will all play a role.

It would be best if you also considered the ceiling price of houses in your area — that is, the maximum value of properties in your neighborhood. It's advisable to contact our Specialist team to estimate the value increase that an extension could provide.

Kitchen expansions, on the other hand, can add between 5 and 10% to the value of your property, while an addition that adds an extra bedroom can contribute up to 20%.

When it comes to predicting how much value a loft conversion will contribute to a property, it isn't easy to give an accurate figure, just as it is with additions.

However, if you add a bedroom with an en suite to your loft conversion, you can expect a value increase of 20-25 percent, assuming the loft conversion was completed to a high degree.

Expect a lesser value rise of roughly 10% in the event of a new home office.

Will an extension or a loft conversion be more suitable for my home?

Consider which extra space will work best for your property when deciding between a loft conversion and an extension.

Loft conversions aren't appropriate for every type of home.  This is due to several factors. Some homes lack loft space while others lack sufficient headroom - you'll need at least 2.8m of unobstructed vertical space.

There will be insufficient space for the additional staircase, or planning approval will be denied in other circumstances.

While many of these challenges can be overcome, you must examine how any additional costs incurred from these concerns will affect any potential profit.

Before deciding, check to see if your loft is suitable for conversion. Most properties, on the other hand, will benefit from extensions. For people who live in terraced or semi-detached homes, side return extensions, as well as rear extensions, can be a terrific alternative. Single-storey back extensions are a great way to create a larger, more social kitchen diner. In contrast, two-storey extensions are a cost-effective option to add living space on the ground floor and an extra bedroom on the second floor.

The most important consideration is how much of your outside space your new expansion will eat up, as well as how much value it will add to your costs.

You must also consider planning approval requirements for larger expansions and loft conversions that do not come under Permitted Development.

Loft Conversion Planning Permission:

●        Add more than 40 cubic meters for terraced buildings and 50 cubic meters for others to the current roof space.

●        Under PD rights, exceed the height of the existing roof.

●        On the main elevation, extend beyond the existing roof slope.

●        Include raised platforms on any verandas or balconies.

●        Furthermore, your property's Permitted Development rights must not have already been used to create a second story.

●        Your PD rights will be affected if you live in a designated location, such as an Area of Outstanding Natural Beauty.

Permission for Extensions in Planning:

Planning authorisation is not required for all extensions. Some will come under approved development, just as loft conversions. The following factors will influence whether or not your extension is considered permitted development:

●        Single-story extensions that extend more than 4 meters from the back of your property will require planning clearance for detached properties. This is above 3 meters for terraced and semi-detached dwellings.

●        Prior Approval is required for extensions of 8 meters (for detached dwellings) and 6 meters (for semi-detached houses).

●        The extension can't be bigger than half the size of the original house land.

●        Planning permission may be necessary if the materials used in addition are visibly distinct from the property.

●        Two-story expansions must be no closer than 7 meters from the property line.

●        Permission is required for front extensions located in front of the main or side elevations and front of a highway.

●        Permission will be necessary if the maximum height of your single-story expansion exceeds 4 meters or is higher than the highest point of the roof.

●        Planning authorization is required for balconies or verandas.
