1. What Are Prefabricated Extensions?
Modular solutions and prefabricated extensions are often grouped together because they share several similarities. In the most basic terms, they are both construction systems that differ from traditional methods by being largely manufactured off-site. This means that the time to build on site is very short, and there is a lot less mess.
As for the differences between modular and prefab extensions? Modular construction is a type of prefabrication where the building kit consists of several separate premade modules. Buildings are designed using a combination of modules from a menu, which can sometimes limit the design. Other types of prefabrication can be made exactly to measure and bespoke, like a timber frame house or the revolutionary hup! building system, which is essentially a kit of pre-cut parts made with mm precision for your own bespoke design and measurements.
2. Benefits of Prefabricated Home Extensions
Let’s imagine you’re using our innovative hup! system for your new extension. hup! is a good example of a prefabricated extension; it uses energy-efficient Ultrapanels in place of brick walls, and these clip together to form the structure. Use hup! to build a conservatory, orangery or single storey home extension, and it won’t just be faster than traditional methods, but significantly faster. A hup! extension can be put together an incredible five times faster than average, resulting in less disruption to your everyday life and a fully useable living space in just a couple of weeks.
Alongside this, there’s far less mess too. As most of the work is done away from your home, you’ll get none of the mess, dirt, and dust that normally comes with construction work. You won’t keep finding brick dust on every internal surface days after the job is completed, and as hup! can use the existing foundations or use groundscrews or pads for new foundations, there’s no need to dig up a huge chunk of your garden first.
3. More Benefits of hup! Prefabricated Extensions
hup! is a cost effective option too. Not having to lay new foundations can potentially save thousands off the final bill, and the rapid assembly means that labour costs are comparatively low too. And that’s without considering the long-term financial savings; hup! is remarkably energy efficient and achieves U-values between 0.12 and 0.17 W/m²K, so getting a comfortable temperature is far simpler. You’ll have to rely on your central heating, resulting in lower monthly energy bills. A hup! extension is 60% more efficient than a traditional brick extension and as they have a lifespan that can be measured in decades, that’s potentially an enormous saving overall.
As a final point here, using a prefabricated system like hup! also guarantees quality. They’re all made to a precise set of standards, and there’s no room for cutting corners. Choose hup! and you won’t even have to think about unreliable builders, there is consistent quality every time.
4. Types of Prefabricated Home Extensions
Prefabricated extension systems like hup! have the same level of design flexibility as a traditional build. You can use hup! to create any kind of living space you can think of, including artist studios, children’s playrooms, kitchens, classic conservatories and much more. They can be built to just about any size required, so whether you’re looking for a grandiose new social space or a relatively compact new room to relax and read novels in, hup! is the perfect choice. As the panels clip together, they can be precision-engineered down to the millimetre, making it a highly adaptable system.
Of note, this also gives them an edge over modular house extensions. Modular systems are terrific and have numerous advantages, but they are often only available in set sizes, which is not great if you want to optimise every inch of space in your property. Modular extensions don’t have the same degree of customisation as hup! does – if you want to optimise your available space to its full potential, pre-made hup! extensions are the superior choice.
How to Choose the Right Solution?
There is a wide range of choices open to you, and it can be bewildering, but it can be incredibly rewarding too. As you work through the various customisation options, such as choosing between bifold or sliding doors or between a vaulted or flat ceiling, a vague idea will start to come to life, and it will feel very satisfying to see the finished product. One of the advantages of pre-fabricated extensions is that you can often explore your designs within software without having to go back and forth with an architect. Another money saving from these innovative solutions.
We recommend finding your local hup! builder and speaking with them. You’ll be assigned to one who can act as a single point of contact and guide you through the process and explore design options in the specialist hup! software. You’ll soon be enjoying a sturdy, comfortable, and stylish new extension that is far quicker than you might expect. And, of course, if you’d like to find some inspiration, check out some of our recent case studies and see if anything catches your eye.
