A range of home extension style and design options

Whatever function you’re looking for your new home extension to accommodate, we have plenty of designs to choose from. Whether it be a kitchen extension, a family living room or a peaceful home office. The first choice you’ll make when beginning your conservatory journey is deciding on either a conservatory, orangery or solid roof extension. Here’s a quick overview, and below you’ll find more information on each.

  • Conservatories – made mostly of high-performance glass, they let it lots of natural light.
  • Orangeries – using more brickwork than glazing, they appear more like a normal room from the inside.
  • Solid roof extensions – ideal for conservatory refurbishments and new extensions to blend with your existing home.

Conservatory extensions

Conservatories and glazed extensions are constructed primarily from glass panels with glazed walls and glass roofs. This is how they differ from orangeries.

Our modern conservatories elaborate on these traditional designs. They incorporate a variety of features for a superior performance and appearance. We use SMARTGLASS® technology for advanced thermal performances, and insulated draught-proofed frames to ensure for a comfortable temperature all year round. With a variety of materials, colour options and decorative features, we can design a made-to-measure conservatory that will add kerb appeal to your home.

Orangery extensions

Orangeries have their roots set in 15th and 16th Century Italy, when they were originally used to grow citrus fruit all year round. Later innovations added glass to trap heat, which is when they started to be used as social spaces.

Orangery extensions usually feature solid brick pillars, large energy-efficient glazed windows and either a glass or tiled roof. We will use brickwork that effortlessly blends with your current home for a seamless appearance. We can include heritage decorative features for a traditional design, or incorporate sleek features for a modern orangery installation. Orangery extensions truly are the perfect solution for homeowners looking to add grandeur and sophistication.

Solid roof conservatory extensions

A solid roof extension can integrate harmoniously with your existing property, depending on the brickwork and roofing material used. With a plethora of styles and colour choices, you can be sure that it will look exactly like the exterior of your home. A solid roof option is extremely thermally efficient because it features integral insulation built into the lightweight roofing system. Its innovative specification keeps the warmth inside in the winter and lets it seep out in the summer, for an optimal temperature all year round.

Our solid roof conservatory option can also be used to revitalise an older outperforming conservatory. It’s an easy conservatory refurbishment installation that will not only modernise its appearance but significantly improve its performance too. This means you can make better use of your old conservatory.

Modern and traditional conservatory styles

Our bespoke glass extensions feature many different elements so we can create lots of possibilities for your home. From an elegant Chartwell green orangery to a crisp black conservatory, or something in between, we’ll install your dream additional space.

Modern conservatory extensions tend to favour monochrome colours and square or rectangular floor plans for a sleek design. Slim-framed windows, bi-fold or patio doors, and straight roofing pillars will all add a contemporary flair. With high-performance glazing adding style, they’ll also let you enjoy the outdoor views. A roof lantern an ideal additional roofing option to add the ‘wow-factor’, acting as a centrepiece.

Traditional conservatory extensions are available in a number of styles, including Victorian, Edwardian and Lean-to. With a plethora of colour choices, including white and cream, we also offer a number of wood effects. This is perfect to add a classical touch to your home. They can suit both glass and tiled roofing systems, and our elegant French doors will add further character.

Conservatory Materials

When building a conservatory, the construction begins with the foundations and base, there is then a choice of uPVC, timber or aluminium for the walls, windows and doors. The structure is then finished with a polycarbonate, glass or solid roof. Component materials have developed a lot over the last decade, with enhanced glazing and frame technology that benefit from improved energy efficiency, security and overall performance; when compared to models built in the last 20 to 30 years. Each material has its own individual features that should be considered when choosing which is most suitable for you. See below for more information one each.

Base and Foundations

The base is the first part of the build. It takes the weight of the finished structure to ensure that there is no future subsidence. It also creates a watertight barrier between the ground and the inside of the new structure to guarantee there will be no problems with damp or water ingress. The depth of the footings will depend upon a number of factors, including the size of the finished conservatory and its proximity to trees.

First, the area where the new structure is to be located will be levelled, then footings will be dug and filled with concrete. Next, a waterproof membrane will be laid across the whole base area, with a block of insulation material on top of that. Then concrete will be poured and tamped, to create a smooth, strong and completely watertight base.

Conservatory Frame Choices

uPVC is the most common choice of conservatory material, and the most cost-effective. uPVC conservatories are durable, low-maintenance and hold strong for many years. uPVC frames have developed over the last decade, with enhanced temperature control and insulation performance, as well as slowing down heat transfer to keep the conservatory cooler in the summer. There’s a wider choice when it comes to colour schemes, including wood effect conservatory frames, allowing us to offer an elegant design that will be consistent with the look of your property.

Aluminium frames offer strong structural design and require very little maintenance. The intrinsic strength of aluminium gives the frame greater durability over long periods of time. In coastal conditions, it’s a good option to withstand the elements. If you’re conscious of the environmental impact, aluminium is a fantastic choice. It’s widely accessible and can be recycled over and over again.

A well-constructed timber conservatory not only looks fantastic but also offers great efficiency and durability over long periods of time. Upkeep requires slightly more maintenance than the other options, but nothing to be overly concerned by. The timber needs to be re-treated every couple of years to ensure the wood sustains its colour. Timber frames generally cost more, but are competitive on performance and give a traditional character. For those with environmental considerations, timber solutions are eco-friendly as the wood comes from sustainable forests and can easily be adapted to fit any property.

Conservatory Glazing Options

Glazing technology has developed considerably with a new generation of glass offering industry-leading performances. We use SMARTGLASS because it offers a completely tailored solution, whatever your colour preference, location and design.

Here’s an overview of how glazing performance is measured.

U-Value measures heat loss through the glazed unit in winter months. The lower the U-Value, the warmer the room will be in winter.

G-Value shows the percentage of the sun’s heat able to pass through the unit. A G-Value of 40% means that 60% of the sun’s heat is reflected or absorbed by the glass, reducing heat build-up in the summer months.

Light Transmittance is the percentage of visible light able to pass through the unit. The lower the light transmittance, the lower the glare within the room.

True Self Clean does exactly that; it cleans itself. Using a specially coated glass, a chemical reaction physically breaks down and washes away dirt.

Warm Edge Technology
– Using a spacer bar that’s up to 950 times less conductive than aluminium, this increases internal temperatures around the edges and vastly reduces condensation.

Which glass is best for me?

This depends entirely upon a number of factors, including your property’s orientation to the sun and the size of the structures. Our SMARTGLASS range offers a number of products with different G and Light Transmittance values to suit specific needs.

The glass we use in the walls of our conservatories blocks over 50% of the summer sun’s radiant heat, whilst being 20% better at retaining warmth in winter than ‘A-rated’ glazing. Available in a three-tier structure, it also increases security, reduces external noises and blocks damaging UV light.

Conservatory Roof Options

For the conservatory roof, you have three choices.  The first is polycarbonate, which is light and easy to install. These days the material has excellent thermal efficiency properties, whilst being the most cost-effective option.

The second is a glass roof. State of the art glazing technology means that you can choose the glass depending on your conservatory’s orientation to the sun. This means the amount of light and heat energy from the sun can be controlled, to give you the most comfortable environment inside. What’s more, you’ll be able to see the sky during the day and the stars at night.

The final choice is a solid conservatory roof, offering exceptional insulation and weather-resistance. They can be finished with tiles that will match your existing property.

Conservatory Planning Permissions & Building Regulations

Conservatories are typically considered to be Permitted Development, meaning they don’t normally require planning permission. Planning legislation has actually been relaxed in recent years, making it a far more straightforward process for you to add extra space to your home. However, it is still required under certain circumstances which we’ve summarised in our expert blog.

Mrs Grimshaw

This is the second time that we have…

This is the second time that we have had StormClad to install some new windows to our home. Cannot fault them at all. The fitters are excellent in their work. We would definitely go back to them should we require more windows.

Third time of using Stormclad…

Third time of using Stormclad (conservatory, door and this time a window). Very happy with product and service. Window installer was prompt, courteous and tidy. Would use again.

Stormclad – highly recommended

Stormclad designed and installed a new front door for us and we couldn’t be happier with it. The door looks smart and is good quality. Everyone we spoke to and met at the company were a pleasure to deal with, and the installation was carried out to the highest standard. Thank you, Stormclad.

Origin Bi-Fold install.

Had my first dealing with Stormclad and what an amazing company to deal with. From the beginning to the very end I cant find a fault with them. I had a window taken out and Origin Bi-fold fitted. Both the installer – Wayne and the plasterer – Martin have done a first first class job. I’m already looking into another bi-fold with them and I suspect the level of quality and detail will again be up there. K

Great service again

Having previously used Stormclad to install doors for us, we had no hesitation in using them again when we required some new windows. We received the same first class service as on previous occasions. From the initial consultation with Sally, subsequent interaction with Allison, to the fitting by Wayne the process was very smooth. Wayne arrived to carry out the fitting at a time which was convenient for us, and worked tirelessly to complete the installation. He was very pleasant, respectful of our home and very neat in his work. We could not have asked for more!
Would thoroughly recommend Stormclad.

Brilliant Service!

Would recommend Stormclad to anyone. We had windows and doors for our new house and we love them. The journey started with Sally, she was great. Very knowledgeable, straight to the point and none of the usual salesperson waffle you get with some companies.
Price was within our budget.
The quality of the products are great. The fitting team, Chris and Tommy were very good, they didn’t stop, tidied up well after themselves and were very respectful of our home.
The office staff were also very polite and efficient.
We will definitely be back in the future for any further home improvements that we decide to do.
Thanks again Stormclad!
