how to build a conservatory?

How To Build A Conservatory

Conservatories are a perfect means of creating an extra living space within your home. They can serve various purposes which includes serving as an avenue to entertain guests, a playroom for the kids and can even be used as a home office, they’re able to open up your property without having to break the bank for the highly expensive renovations. So if you wish have a conservatory constructed in your home, it’s either you do it yourself or hire a professional. Doing it yourself will help you save some money but can also end up disastrous. So if you lack the confidence to undertake this project by yourself, then it’s strongly recommended that you hire a professional who can guarantee the best results. In this guide, you’ll discover all steps required to build your own conservatory.

✓ The Base. Due to its durability and cost, concrete happens to be the most used material for conservatory’s base. Firstly, measure the enough area to accommodate the conservatory. Dig at least 1 metre deep and ensure it’s level. Fill with damp membrane and pour your concrete mixture in evenly till it reaches level ground. Once done, make sure that the base is totally dry before erecting the conservatory

✓ Building. Basically you can start by constructing the walls and ensure that they’re sturdy and secure, putting into consideration their measurement.

✓ Roofing. Good news here is, DIY conservatories will already come with the roofing in place, so you won’t have to bother about this stage when building. They usually come with an acrylic roof which is easy to install and maintain.

✓ Flooring & Finishings. Starting from the roof, ensure that there’s sealant on all areas where air can pass through. For the flooring, you’ll have to choose your patio slabs or tiles to go outside of the structure. You can apply these with a thin layer of concrete or onto screed flooring.

how much is a conservatory roof?

How Much Is A Conservatory Roof?

If you’re setting a budget for your new conservatory structure or perhaps you already have one and thinking about replacing the roof, knowing how much a new conservatory roof will cost from the onset can save you a lot of headache. However, knowing the correct cost won’t be easy as this is determined by a plethora of factors which is unique to each individual. In this article, we’re going to give a rough estimate of a conservatory roof cost so as to help you make an informed decision moving forward. Let’s have a look!

In order to determine the cost of your conservatory roof, the type of roof you go for must firstly be determined. This is because there is a wide array of conservatory roof types with each having its own unique price. You can opt for the uPVC glass roof, a tiled roof or a glass roof.

With so many other factors to consider, we’ll not be able to give you an exact amount. However, in general, a conservatory roof can cost anywhere within the range of £2500 to £8500. You may also quoted for more or less depending on your roof type as well as the specifications you opt for including the size and type of your conservatory. For instance, if you own a Lean-To conservatory with a size of 3.1m by 3.1m, for a glass conservatory roof, you can expect to spend anywhere within the range of £3000 to £3500. Meanwhile for a Victorian conservatory roof with a size of 5.1m by 5.1m, the cost will range between £5000 to £8000.

Therefore the type as well as size of your conservatory really does greatly impacts the cost of your conservatory roof.

what is a conservatory?

What Is A Conservatory?

A conservatory is basically a structure constructed on a property that’s usually attached to the side of a home. It’s a room as well as a greenhouse that’s constructed with the help of a wide range of materials which includes bricks, wood, glass and polycarbonate. A conservatory is typically built with a great amount of glass which enables it to offer huge amount of sun and light. During construction, the idea is always to muster sufficient sunlight for the plants while also enabling a cosy room within the structure especially during the cold months. Generally, conservatory extensions’ walls are made of over 50 percent of glass, while their roofs are usually made up of more than 75 percent glass.

Thanks to the advancement in technology, conservatories have also greatly developed over the years. They’ve significantly evolved from the usual luxury greenhouses to normal and everyday home extensions. Conservatories have also grown to become very energy-efficient while also providing super comfort to the extent that they’re now being used throughout the year. And while it’s formerly known to be an occasional room, it’s now more of a home’s extension.

Legally, conservatories are usually covered by what’s called the permitted development rights which exempts them from both planning permission and building regulations. The conditions below form the legal definition of a conservatory to differentiate it from an extension.

✓ Below 30 square metres in size

✓ Constructed at ground level

✓ Separated from the main building by external walls, doors or windows.

✓ Possesses its own stand alone heating system

✓ The glazing as well as fixed electrical fittings are in compliance with the relevant building regulations.

do you need foundations for a lean to conservatory?

The short and simple answer to this question is yes, just like other new extensions, you must have a foundation done for your lean to conservatory. In order to transfer the building’s weight to the floor safely, there’s a need to construct a foundation. Without it, the structural integrity of the extension would be heavily compromised. What’s more? While there’s no minimum depth requirement for a lean to conservatory, there are multiple factors that can affect the depth as well as type of the foundation. Let’s take a look!

 

  • The nearby trees. What trees do is to absorb water from the soil which can affect the foundation significantly. When water is absorbed from the soil, the soil shrinks which affects the foundation’s strength. The size as well as type of the tree will determine the extent of the water absorption from the ground.
  • The soil’s suitability. The weight that each soil can withstand varies and even more so, when environmental factors have more effect on certain types of soils than others. For instance, chalk is able to drain water away relatively easily which means that nearby trees will only have a little effect on its quality. Clay, on the other hand, shrinks when drying and also retains a lot of water. This means that nearby trees will have huge impact on clay soil which will compromise the structural integrity of the lean to conservatory. Therefore, since changes to clay mostly occur to about 0.75m depth, foundations on the soil should be constructed deeper to compensate.
  • Undisturbed ground. Before the foundations are laid, there’s a need to identify grounds that hasn’t been built on and this usually takes a depth of about 1m (this figure may vary especially in regions where drains have been laid).
How to build a wooden lean-to conservatory?

Lean-to conservatories are often known as Mediterranean conservatories or sunrooms and are a great way to add more living space when you’ve only got a small amount of room to work with. They usually have clean lines, a rectangular shape and attach to the side or rear of your home, which makes them one of the easiest conservatory types to build yourself.

So how do you build a wooden lean-to conservatory? The first step is to decide what you want it to look like. Most lean-to conservatories are constructed of glass and the wood frame, but you can choose to have dwarf walls too. Dwarf walls are low brick walls that are useful if you’re planning to plumb in radiators, have air conditioning installed or put plug sockets in the conservatory.

When you’ve decided what your wooden lean-to conservatory is going to look like, you’ll need to get the materials. You’ll need to choose a hardy wood – oak is the most expensive but also the most durable – and source glass for the windows. You’ll also need to decide on a roof material and work out the correct pitch.

The first step to building your wooden lean-to conservatory is to dig the foundations. You’ll then need to level the earth, then add concrete to the correct height, which should be lower than your property’s existing damp course. Then, you’ll build up to the damp course, which will be your conservatory’s floor level. Don’t forget to make sure it’s even.

If you’re building a dwarf wall, start it from the base and build up to no more than 1 metre high. Once the cement is dry, place external sills on top of the dwarf wall. You’ll then need to secure the frames; start with the one that secures to your property, then do the same for the rest, connecting outwards until they meet from the two sides. Then put up your doors.

Now it’s time to build the roof. This should be simple if you’ve bought your own custom-made kit. Place the roof ridge on top of the frames, then add the roof rafters between the roof ridge and hip bars. Fit your glazing sheets and guttering – it’s important that your wooden conservatory roof has guttering just like your house, otherwise your conservatory roof won’t last very long and could even cause rainwater to rot your wooden frames.

Once you’ve built your wooden lean-to conservatory, all that’s left is to decide on how you want to decorate it. But if this all sounds like too much, get in touch with specialist wooden conservatory installers who will be able to give you a quote for building you a lean-to conservatory.

Do conservatories need to be double glazed?

In 2002 the Government amended Building Regulations governing the replacement and installation of glazing units. For the first time, windows had to meet energy efficiency standards and tough thermal performance levels. For new window units you must have efficiency ratings of at least a level C.

What’s the cost of a hardwood conservatory?
If you want a wooden conservatory, a hardwood conservatory is the best option. Softwood conservatories are cheaper because the wood grows faster, but they aren’t as weather resistant so won’t last as long. Choose a hardwood conservatory and it should last you over 15 years. Hardwood conservatories will set you back anywhere between £35,000 and £60,000, depending on your requirements. Of course, the larger your conservatory, the more it will cost, but other factors such as the type of wood, the finish and any dwarf walls will make a difference too. Oak is the hardiest type of wood, making it the most expensive – but it can be finished with a bug and pest resistant coating and still retain its polished look, so many people think it’s worth spending their money on. Other hardwoods used for conservatories are idigbo, Brazilian cedar and luan and are cheaper than oak but are still a great option. If you’d prefer to keep the cost of your hardwood conservatory towards the lower end of the range, choose one of these. You can still get them in a variety of finishes and they are still natural heat retainers, so you’ll get a conservatory that is as warm as it can be. If you want to use your conservatory all year round, it might be worth thinking about having dwarf walls installed with your hardwood conservatory so you can plumb in radiators.

how long do upvc conservatories last?

How Long Do UPVC Conservation Last?

UPVC conservatories are common features on residences across the UK for a good reason. Not only do they give you the extra living space you so much desire within your home or property, but they also go a long way to add value to your property. So if you’re also thinking about constructing a UPVC conservation within your home, you’re probably not alone! One of the several benefits of the structure is also its longevity, however this is dependent on a number of factors. Let’s take a closer look!

Modern UPVC windows will normally last between 20 to 25 years, however some are able to last much longer provided they’re properly maintained and top quality materials are used. And thanks to improvements in colour technology, the finish on UPVC tends to last much longer too.

Some of the factors that can go a long way to determine the longevity of your UPVC conservation includes the type of roofing materials used, how well it’s being maintained, the location or placement of the structure, replacement of individual conservatory parts, as well as insulation.

The type of roofing material for a UPVC conservation can either be glass, polycarbonate or tiles. The glass and polycarbonate roofs usually lasts for a minimum of 20 years when it’s properly installed and provided with the necessary upkeep. Meanwhile, tiled UPVC conservation roof are generally expected to last up to 50 years which is significantly longer than the counterparts - glass and polycarbonate. Interestingly, they require little to no maintenance and are also very unlikely to get damaged during the upkeep.

It’s also very important to make use of a reliable and reputable company to have your UPVC conservatory installed. This is because your structure can only be as good as the company responsible for its installation. So if you require a structures that will last for decades, you should pay great attention to the company you’ll hire.
