How Do You Extend An Orangery Into A Kitchen Extension?

At Dempsey Dyer, we supply many orangeries for the trade. Orangeries are versatile because they bring a plethora of natural light into your customers’ home. They can be used for a gym, an extra bathroom, or a kitchen. Inform your customer that orangeries will give their home plenty of elegance, style, and beautiful aesthetics for their property.

An orangery is a versatile way of choosing a brand new room.  But your customer might be wondering how they can transform the orangery into a kitchen extension. Our designs will help transform your kitchen if you get stuck. In this article, we will show you ways of transforming your kitchen if you get stuck.

Can I Expand My Orangery into a Kitchen?

The first thing a customer might ask themselves is whether they can expand their orangery into a kitchen. Orangeries offer a bright and airy space that holds extra space for tables and chairs. They flood your customers’ property with natural light, giving you a bright and airy feel in your customers’ homes. Combine this with a soothing ambience in the evening, and this creates the perfect atmosphere for the family.

The addition of a roof lantern can give your customer extra space on their property. This adds lots of natural light while giving beautiful panoramic views. Inform your customer that this will save on their energy bills as they don’t have to use their central heating.

Does a Kitchen Extension Need Planning Permission?

Before considering the orangery in your home, it is important to decide whether the kitchen extension needs planning permission in your customers’  home. However, it depends on the type of extension your customer is looking for. As a result, some single storey extensions will come under permitted development rights, enabling building work to be undertaken easily. Our installers at Dempsey Dyer are efficient and will get to work straight away, providing friendly customer service to match.

If your customer lives in a detached house and they want a single storey extension, then it must not go beyond the rear wall of the original house. A rear extension should go no higher than 8m in depth for a detached house and 6m in depth for a semidetached house.

There are some instances where the kitchen extension will require planning permission. To obtain this, it is best to check with your local planning authority or council.  Building regulations ensure that the extension meets technical requirements, so it is safe for your customer.

How Much Does a Kitchen Orangery Cost?

When planning on your customers’ kitchen extension, it is important to get an understanding of how much the kitchen extension will cost to match your customers’ budgets. Inform them that the total price will come down to how much joinery is needed and customisable options for building your customers’ orangery.

Bring the orangery up to the standards of a kitchen extension will cost you around £80,000 – 90,000. Every orangery is different and created to your customers’ bespoke needs, so the cost will depend on your customers’ requirements. Every build starts with a plan and plenty of inspiration. Our friendly team of installers will help your customer get a design bespoke to their requirements.

How to Make the Most Out of Your Kitchen Orangery

When creating your customers’  extension, there are many options for you to consider. It is imperative to think about what your design involves. A kitchen design will include, amongst other things, where the kitchen cabinets will go, alongside the cooker. Let your customer know that there should be a clear pathway to the hob, sink, and fridge for convenience and ease of use.  A floor plan will help you understand how the kitchen will link to adjacent rooms.

Another thing to consider is whether a kitchen orangery should connect to the garden. This will create a seamless link that enhances the natural light, resulting in a welcoming atmosphere. If your customer has children or pets, this will be a great way to keep an eye on what they are doing. It is important for your customer to think about how they want to open up the door. Let them know that they can consider a bifold door or French door, which is perfect for extra ventilation.

Create a Multi Functional Space by Adding an Extra Roof Lantern

With a kitchen being a communal part of the house, one way it can be transformed is to create a multi functional open plan space. This includes adding sofas or chairs, giving guests plenty of options to sit. One idea to bring this out is a kitchen island. Inform them that this creates a central hub of activity, alongside a social hub to prepare food or even a brunch bar. Include draws and a sink so dishes can be washed up.


Orangeries are a superior choice for the modern homeowner as they add character and value to your customer’s property. this is a strong design that lasts for years thanks to low maintenance finishes and stunning aesthetics.

Window & Door Colour Trends

Create a stunning first impression for any customer’s home with a new window and door installation. Simply changing a window and door profile changes the way a home looks and performs.

Although brightly coloured front doors or bold window frames are not new, colour technology has come a long way since the limited range of shades previously offered to homeowners. Because we manufacture many of our products and work with leaders in the industry, we can offer bespoke window and door designs in a selection of unique colours.

We’re proud to offer a wide range of windows, doors and conservatories created bespoke for your specifications. Whether you’re looking for timber, uPVC or composite, our products lead the way in aesthetics and performance.


White windows and doors

White windows and doors are timeless and will never go out of style. They are one of the most popular choices in your local area because they are cost-effective and won’t become dated.

White is versatile and can suit almost every style of home. They can match any colour interior design and curtains, delivering a clean look every time. Avoid combining white windows with white render because they will likely weather at different rates. We recommend pairing white windows with cream and off-greys.


Cream windows and doors

Although white windows and doors are popular, the cream is a softer version that feels less clinical. Some people feel like white lacks personality, whereas ivory or cream maintains that clean aesthetic with a more heritage finish.

Cream uPVC windows and doors are a fantastic option for most UK homeowners, as they can fit well into most house styles and even add to the kerb appeal of a property.


Grey for windows and doors

For many modern interior designers grey is the new black when it comes to windows and doors. Grey windows and doors break away from traditional white, black or brown to set a property apart. Grey will allow customers to enjoy a modern twist on a traditional profile.

Grey is a complementary colour to raw stone or reclaimed building materials. Grey profiles will also seamlessly blend into more subtle and bolder colour-coordinated designs. We offer Anthracite Grey, which is a dark grey hue named after the coal it resembles.


Black windows and doors

If your customers enjoy a more contemporary and minimalistic style, black doors and windows can elevate the look of a building. Black profiles will create a dramatic statement that suits all home styles in your area.

Black windows can accentuate the external views, as the light that floods into them wash out the darker profile. They don’t need curtains to look good, perfect if your customer has a minimalist interior design.

If your customers are interested in a darker profile but are concerned about having pitch-black profiles,  choose darker shades like grey, plum and navy blue.


Natural wood effect windows and doors

Our windows and doors are available in stunning woodgrain finishes. These finishes mimic the look of traditional timber only have none of the durability issues. If you are looking for a low maintenance replacement for a wooden door, our woodgrain foil uPVC profiles won’t rot, warp or split over time and with wear.

Your customers will enjoy a window or door which mimics the look and texture of timber, with all the performance benefits of modern uPVC. Black and grey windows and doors are low maintenance because their darker shade will hide grime and dirt, making them look cleaner for longer.

If you are looking for a deep and rich tone, Rosewood is an extremely popular shade and looks good when paired with classic red brick architecture. Light oak is a more neutral wood tone that is more versatile.


Green windows and doors

Green hues like Sage Green and Chartwell Green are elegant choices when installing windows and doors. This traditional tone has been popular for styles and is often found in country homes.

Chartwell green is a more pastel tone that particularly works well as a front door colour. It is often paired with sophisticated silver or gold door handles and hardware to create a stunning first impression.



We hope that this article has helped you choose which colour is the best for your window and door installation project. Whether you are working on a modern apartment, a traditional cottage or a heritage home we will have the right tone for you.

Windows & Doors For Traditional Style Houses



At Dempsey Dyer, we supply and install windows and doors for the trade. If your customer lives in a traditional property, an upgraded window adds plenty of character to their home. If you are looking to learn more, get in touch with us today.

When it comes to windows, the traditional style requires that they maintain symmetry. Try to match the existing window sizes, shapes, and materials as closely as possible. Sticking with wooden frames can help keep the traditional look alive, but vinyl frames are also a popular choice for durability and cost. Look for windows that feature sashes made of wood, wood-clad, or vinyl.

What Are Traditional Windows and Doors Made From?

Traditional-style windows will include muntins or grids, which refer to the interior panels in a window. If you’re looking for complete authenticity, arched or patterned glass designs can enhance the historic look further. As for doors, the designs should reflect the style of the architecture and create a unified look. Whether you choose wood, wood-clad, or fibreglass, the door should match the rest of the home’s facade. Don’t overlook the hardware, be sure to find finishes that will enhance the door’s primary style. If you’d like to capture a more classic look, choose a six-panel wood door with an arched or keyhole window.

How to Achieve a Modern Look or Your Traditional Home

 If you’re striving to go for a modern look, opt for a fibreglass door with a sleek design and contemporary hardware. If you’re wanting to add a traditional look to your home, one of the best ways to do this is by carefully choosing your windows and doors. Making sure the windows maintain symmetry is key – try to find windows that are a close match to the existing size, shape, and material of your home’s architecture.

Wooden window frames are popular for a traditional look, but Vinyl can also be used for its durability and affordability. When choosing a door, the design should be complementary to the existing style of the home and create a consistent look. Make sure the material – such as wood, wood-clad, or fibreglass – matches the facade of the home. The hardware plays a big part in the overall aesthetic too – find finishes that will best enhance the door’s primary style to achieve the right look. If you’d like a classic or vintage look, opt for a six-panel wood door with an arched or keyhole window.

Which Traditional Style Doors Are Popular

For traditional-style doors, you’ll want to consider panels, designs, and hardware that are authentic to the era. Wooden doors usually require careful attention and maintenance, but their durability and classic look is worth the upkeep. Try to match the exterior door to the architectural style of the home. Traditional-style doors may have simple glazing patterns or multi-pane glass designs.

Inform your customer that composite doors are a popular design for your home. If your customer is looking for a modern design for their home, composite doors provide the best of both aluminium and uPVC, alongside a robust thermal core. Inform your customers that they will be kept safe for many years to come.

Another door that is useful for traditional properties is a stable door. Inform your customers that this is a useful back door that offers the best of both worlds. Your customer will get a rustic country charm alongside fantastic security. This is a unique selling point as intruders will be warded off easily. A stable door includes an opening that lets in plenty of natural light, so your customers will save money on their energy bills. And, it will make their home brighter, increasing their market value as  a result.

What Hardware is Available for Traditional Doors?

Additionally, period hardware is available in many forms, including latch sets, handles, door knobs, and hinges. These may also be made of brass, iron, bronze, steel, or pewter to really capture the period style of the house.

Inform your customer that we offer these options in a variety of styles. This gives them plenty of options to customise their windows and doors.


We believe that ultimately, whether you go for a modern or traditional look, the choice should be up to you. At Dempsey Dyer, we have years of experience when it comes to installing timber windows in your property.

Timber Windows – Repairing vs Replacing

Windows are one of the most important aspects of any property when it comes to both style and performance.

When You Should Repair Timber Windows

In some cases, it may be the right decision to repair existing timber windows rather than replace their profiles entirely. First, you’ll want to be able to identify the signs that windows need repairing or replacing. Some tell-tale signs we’ve seen over the years range from physical deterioration to sub-par thermal performance – if heat is escaping out of your windows, now more than ever it’s vital to ask quickly to avoid wasting energy.

If aesthetics are a primary concern, then the good news is that the paintwork of your timber windows could be rejuvenated relatively easily. A fresh coat of paint can last almost 10 years on your wooden windows, so if that’s all it takes, it could be a decent option to buy you a little time until you want to replace your timber windows altogether.

From a performance point of view, you may have noticed rotting or warping having an effect on older timber window profiles. The good news is that if this is spotted early enough, it can be treated quickly and relatively easily. Skilled repairers might be able to separate any damaged sills from the rest of the profile and replace these separately, so you won’t have to swap out the whole window.

In all cases, whether you’re looking to repair or replace or just get some advice, it’s always best to consult the experts. If you’re handing delicate timber window components or potentially hazardous fumes on older window profiles, you’ll want to make sure your repairs are carried out safely and responsibly.

When You Should Replace Timber Windows

If repairing isn’t an option, you’ll want to look at replacing your existing timber windows with the latest, most stylish and highest performance profiles on the market – such as those manufactured by Dempsey Dyer. Our specialisation in the industry means that we know what it takes to make windows that are truly the best of the best.

Perhaps you’ve looked at repairing timber windows as the first option. If you’ve found rot and mould early enough, then it can be treated. But in some cases, this has developed too far and compromised the bulk of the window profile. As such, you won’t want to waste time and money trying to fix a broken timber window that will never perform as well as it needs to.

After all, you might end up having to do it all again sooner rather than that. In this case, replacing your timber windows will be the best time-efficient and cost-effective choice in the long run.

For many homeowners, the opportunity to replace their windows opens up a wealth of existing design opportunities. With trends always changing and evolving, you’ll want to keep up with the latest style options. Whether that’s in colours or hardware, since you last replaced your timber windows (if ever) there are sure to be plenty of new options on the market to suit any home and express a customer’s personality uniquely.

From a thermal efficiency point of view, there’s never been a more pertinent time to replace older, outdated timber windows. This is because many wooden windows feature single glazing. Compared to double or triple glazing, single glazed windows suffer from sub-par energy performance, with hot air easily escaping. With upgrades to new double glazed timber windows, homeowners can save money on heating bills and stay more comfortable all year, all ways.

How Aluminium Windows Have Become More Thermally Efficient

With energy efficiency at the forefront of everyone’s minds no matter where they are in the journey – from manufacturers and tradespeople to homeowners – it’s only right that there is a lot of discussion around which type of windows and doors are the most thermally efficient.

One of the most popular types of windows at the moment is aluminium. This material offers a distinctive, striking aesthetic that is ideal for modern homes looking to retain their up to date appeal or even traditional homes looking to bring themselves up to date.

But how does aluminium compare to timber and uPVC as an energy efficient window? It’s one of the products we offer here at Dempsey Dyer, and thermal efficiency is highly important to us, so we want to make sure our installers and homeowners stay educated about its properties to make an informed decision. That’s why we’ve put together this guide on aluminium windows’ thermal efficiency. Read on to find out more.

Older Aluminium Windows

Several years ago, aluminium windows were not thought to be one of the most energy efficient options on the window market. That’s because, as a material, aluminium has high levels of heat transference. So, once installed, when customers would heat the inside of their homes, the windows would absorb this heat – and its transference properties would pass the warmth to the outside world, so it was lost.

From an energy efficiency perspective, this is far from ideal. If homeowners are spending money and energy heating their homes, the last thing they want is for it to escape – what’s more, frustratingly, with the help of their windows, rather than them stopping it. This leads to lost heat and therefore lost money.

Additionally, aluminium windows’ thermal transference properties led to them expanding in heat. With the profiles changing along with the temperature, the window seals would become damaged, leading to condensation, which is as unsightly as it is unhealthy. Older aluminium windows could even break away from the glass as a result of this expansion, which only exacerbated the issue of them losing heat too!

However, this changed with the development and popularity of a thermal break for aluminium windows.

Thermal Breaks – Explained

A thermal break is what has made aluminium windows more viable and more popular as a result. So what is a thermal break? For those who are not aware of what it is or perhaps more likely how it works – put simply, a thermal break separates the inside of the outside from the window.

This means that when one side of the window becomes too hot, there is an extra layer in between that stops the same thing from happening on the other. It’s the same case for the cold, too.

A thermal break is an excellent addition to aluminium windows. With this in place, it reduces the issues that these profiles were facing previously – condensation and heat transference, and therefore extra expensive for customers in all cases. Now, with a thermal break, aluminium windows are as modern in their performance as they are in their aesthetics.

Here at Dempsey Dyer, we are at the forefront of development in the fenestration manufacturing sector.

Sustainability and thermal efficiency are hot topics, which is why we’re keen to inform our customers about aluminium windows and how they relate to this. With energy efficient glass and profiles manufactured with thermal properties in mind, homeowners will be sure to save money on their bills and be proud of their investment.
