  • Our team will be on site until completion (usually within 2 weeks), focusing on only your conversion
  • We recycle your old window frames and conservatory roof, ensuring minimum waste
  • Unlike with traditional extensions, your garden will be left in the same state as it was found

Why upgrade your conservatory?

It's in disrepair

If your old conservatory roof is leaking or other areas of it look like they have seen better days, it might be time for an upgrade. 

It's too hot or too cold

It's common for old conservatories to get too hot in summer and too cold in winter. You can solve this with a conservatory conversion. 

Energy efficiency

The modern EurXtension system is more energy efficient than old style conservatories, which let out lots of heat due to the materials used. 

You want to add value

Want to add value to your home with a new room? Converting your conservatory with a brand-new, stylish and energy efficient extension will increase it's appeal.

Building from the base up

Our conversions are designed to be versatile. That means you can create a bespoke design that suits your home.


SIP panels are so light they can be built directly onto your existing concrete base, which cuts out cost and time. We’ll use your existing base.


Our wall system comes in a range of finishes so we can create an extension that blends seamlessly with your home. There are several options to select from bricks to match or rendered to contrast.

Windows & Doors

Choose from our vast range of window & door styles to match or contrast with your home. Large expanses of glass & sliding doors allow natural light to flood the space.


Our house extensions have a fully insulated, solid tiled roof to keep your room warm in winter & cool in summer. And why not add some rooflights too, they’ll let in extra light so your space will feel beautifully bright & airy.

Can I customise my EurXtension?
Absolutely! EurXtensions can be tailor-made to create your dream space. Choose the shape you require, decide where you want them and then select your windows and doors from our range of styles and colours, choose your roof style, tile colour and if you like why not add rooflights for that extra flood of natural light!
Will a EurXtension add value to my home?
Whether you’re looking to add a new extension or replace an old conservatory, a EurXtension will undoubtably add value to your home.  Adding additional rooms to a house will always increase the value of the property, and with recent reports indicating that an old conservatory can de-value a home by as much as £15,000 due to their reputation of being too cold in the winter and too hot in the summer, choosing to add a EurXtension to your home will add value.
How much does a house extension cost?
If you're considering a house extension, keep in mind that several aspects can impact the overall cost. These encompass elements such as the extension's size, style, and the amount of glazing in the walls and roof. Don't forget to explore modern solutions like Eurocell's EurXtension, which could provide a valuable addition to your project.
Do I need planning permission for an extension?
Orangeries or house extensions may not always require planning permission, usually falling under permitted development if size and criteria are met. For full criteria, visit the Planning Portal website. Consider Eurocell EurXtension for innovative options.
What's the difference between orangery and conservatory?
A conservatory boasts a glass structure with a pitched glazed roof perched upon a brick base, whereas an orangery features a brick structure with spacious windows and a flat roof incorporating a glass lantern.
How long is the house extension process?
The key time determinant for a house extension is its foundation work. Duration depends on ground conditions and need for piled foundations. After the base, using Eurocell's EurXtension could speed up construction, taking weeks with pre-fab or months with traditional methods.
Are SIP panels an energy saver?
SIP panels are indeed energy savers, boasting roughly 50% higher energy efficiency compared to conventional timber framing. By ensuring homes are airtight and minimising heat leakage, SIPs effectively lower energy costs for occupants while also reducing carbon emissions released into the environment.
