Modern and Traditional Conservatories

Do you remember old conservatories that were freezing in the winter and sweltering in the summer? We don’t sell those. Instead, we curate high-performance glazed extensions that can be designed specifically for your unique needs and space. 

Our contemporary conservatory alternatives include using innovative and state-of-the-art materials to create a warm, elegant space that you can use all year round. Make your conservatory stand out by using different colours and styles; anthracite grey gives a modern feel while also blending into the space around it, and our hybrid tiled and glazed roofing options mean your conservatory will feel like an integral part of your home.

Talk to us to find out what we can do for your space; we are registered installers of Ultraframe conservatories, offering stylish conservatory roof systems such as Ultraframe, Ultraroof, Livinroof and Ultrasky options. These cutting edge roof options let you decide how much glass or tile you want your roof to have, without sacrificing aesthetics or performance.


Light and comfort, perfectly balanced.

Homeowners no longer have to choose between a solid or glass conservatory roof. That’s because the Livinroof combines the best elements of both. Extend your living space and create a comfortable room that’s light, bright and suitable for year-round living.


High performance, tiled conservatory roofs.

Ultraroof is the lightest and strongest tiled conservatory roof on the market. It is designed to sit on old or new window frames and doors; unlike other solid roofs, it never needs a tie bar.


Let the light flood in.

With fewer and slimmer bars than other systems, the Ultrasky Lantern has the flexibility to respond to your design aspirations. Whatever style of property you own, the Ultrasky lantern will enhance it – meaning you’ll be able to create a traditional or modern effect.

We have a wide variety of glazing options for our conservatories, including self-cleaning, noise-reduction, UV filters and much more. Our high-performance glass retains heat in the winter and reflects the worst of the sun’s glare in the summer, so it is a comfortable temperature whatever the season.

We spend the time to understand what you want from your glazed extension so that we can provide a multifunctional space that you can use all year round; for entertaining, relaxing or spending some quality family time. We want your conservatory to be as individual as you are, so just organise a home visit and we can talk you through all the options available to you.

Common questions

Is it uPVC or PVCu?

You might have seen different people refer to uPVC, and others to PVCu – but which one is correct? In fact, they both mean exactly the same thing; unplasticised Poly Vinyl Chloride. In English, those acronyms result in uPVC, but in the 80s it was formally changed to PVCu as the majority of European languages say the noun (PVC) before the adjective (u). Despite the change, in the UK the plastic is often still referred to as uPVC. There’s no need to worry – whichever way it is written, it still refers to the same durable plastic that we use to create many of our doors, windows and conservatories.

Is it worth having a conservatory?

Having a conservatory can make a real difference to your home. It is one of the easiest ways to add space to your home without having to apply for planning permission – which can be a slow and costly process – or wait weeks for a full extension to be completed. The extra space is extremely versatile; it can be space for you to hold dinner parties, a playroom for children that doesn’t mess up the main living room of the house, or even as a calm space for you to feel closer to nature. If you’re hankering after a little extra space in your home, then a conservatory can be a great option to extend your home without the hassle.

Are conservatories cheaper than extensions?

In general, conservatories are always cheaper than extensions of the same size. This is because extensions use a variety of different materials, including concrete, bricks, a roof and windows, and have to comply with certain insulative regulations. A conservatory on the other hand is made mostly of glass with either an aluminium or PVCu frame, and so once it has been made in our state of the art factory, it is much easier and faster to build and secure. If you’re looking to build a conservatory on your home but aren’t sure how much it would cost, contact us today for a free, no obligation quote.

Do you need planning permission for a conservatory?

In almost all cases it is not necessary to apply for planning permission for a conservatory, as it usually falls under “permitted development” rights. This means you can extend your property as long as it is not excessively large and the roof isn’t higher than your existing roof. If you contact us with a conservatory that might need planning permission, we will let you know so that you can take the appropriate steps to do so. All our products are approved by CERTASS which provides a Building Regulation Compliance Certificate for any work we carry out. If you’re not sure whether your conservatory would need planning permission, contact us today to find out more.
