Bespoke Designs

We know that no two homes in Sheffield are alike, which is why we offer completely bespoke designs so that our customers can create a conservatory that is perfect for their homes. We will work closely with you to ensure that the design is exactly as you had envisaged.


Our conservatories are built to withstand harsh weather conditions so that they last for decades. In fact, if maintained properly, our uPVC conservatories can last for over thirty years! Unlike other materials, like timber, uPVC does not absorb moisture, so it will not rot, bow, or crack.

Highly Secure

We know that keeping your home safe is your priority, which is why we use market-leading security systems. Our windows and doors feature multi-point locks that cannot be forced open, offering optimal protection for your home.

Frequently Asked Questions

Still have some questions? Please feel free to contact us, and we can help. In the meantime, we have answered some of our most frequently asked questions that may be useful.

What’s the difference between an orangery, conservatory, and garden room?

This is one of our most asked questions, so if you are unsure, you are not alone! A conservatory is a glazed extension that is connected to your home. An orangery is also connected to your home, and the design combines the glazed elements of a conservatory with the brickwork of a regular house extension. A garden room, on the other hand, is free-standing and built with composite materials. If you would like to discuss which options are best for your Sheffield home, get in touch, and our expert team can offer you advice.
