How Long to Build a Conservatory?

Most of our conservatory build projects take less than four weeks. We can build a conservatory in some conservatory styles, such as Ultraframe and Loggia conservatories, much faster once the materials arrive on site.

That’s the quick answer. Now let’s dig into some more details to help you plan your next conservatory project properly.

DIY Conservatories vs Professional Conservatory Builders

One of the first questions you need to answer is “Can I build a conservatory myself?” There are a few reasons to consider DIY conservatories:

  • You will save money on labour costs.
  • DIY brings a feeling of satisfaction and ownership
  • Building your own conservatory may give you more control over the finished product.

However, we believe in the value of a skilled builder. Hiring a professional to build a conservatory comes with benefits.

  • Professionals use the best tools and equipment to produce amazing results.
  • Experienced builders know many tricks to create beautiful home improvements.
  • Working with a professional ensures building regulations compliance.
  • Certified conservatory builders insure themselves against damages.
  • Building work by a professional installer is almost always faster.

That last point is really important if you’re interested in speed. Our teams have the experience it takes to finish your conservatory build in the least amount of time.

Whether you choose a professional conservatory installer or do it yourself, the planning process is going to be very similar.

Planning Your Dream Conservatory

You are really welcome to spend hours, weeks, or even months thinking about your home improvements. We don’t want to pressure you into making a poor decision. Instead, take all the time you want to consider the best build for your home and family.

Here’s a quick overview of how you can approach the planning process.

Decide on the Building Site

Take a good look at your house and decide on the area where the extension will fit. Consider these questions:

  • How much of the conservatory will attach to the wall of your home?
  • How much space do you have for projection (the distance the conservatory extends from the home)?
  • How tall will your build be?

These are all factors in planning the conservatory size.

Choose Your Conservatory Style

Once you know how big the extension will be, you can begin looking at conservatory styles. There is something for everyone’s home, and you have dozens of choices.

Here are some simple guides:

  • Small spaces, less than 9 square metres, will do well with lean-to styles.
  • Wide conservatories that do not project far look great with a flat conservatory roof and skylights.
  • Long conservatories often feature Victorian or Edwardian conservatory base styles with pitched roofs.
  • If you have a lot of space, a T-shaped or P-shaped conservatory will make a grand extension for your home.

These are just a few ideas. For even more inspiration, you can check out our guide on the best conservatories modern homeowners can install.

Get Quotes from Conservatory Installers

After you settle on your preferred style, you can reach out to suppliers and installers for quotes. If you’re building your own home improvements, you should ask about delivery times for the products you’re purchasing.

Reputable installers, like Best Glaze, will be able to show you a portfolio of work from previous customers, walk you through the build process, give you details about the products, and help you plan a thorough timeline for your home extension.

How long does it take to plan a conservatory build? The dreaming phase could take as long as you want. The quotation phase shouldn’t take more than a few days.

Four Stages of Conservatory Construction Work

With everything planned, you can start building. How long will it take to finish your conservatory? There are a few factors we’ll touch on along the way. However, our normal estimate is less than a month.

Let’s take a quick look at the stages of construction so you know what to expect.

Dig and Lay the Base

The conservatory base you use will determine how long this phase requires. Building teams will dig and level the area. Then, they’ll lay a foundation so they can install the frames safely. Professionals, like Best Glaze, will minimise the disruption to your home and carry away all waste material.

Digging and laying a full concrete foundation could take up to a week. This allows for the initial work and three or four days for the site to settle.

There is a faster way to install a foundation and dwarf walls. We strongly recommend the Durabase system for conservatories. Here’s why:

The Durabase System features a steel base that is bolted together on-site and fixed to the wall of your home using resin and anchor bolts. We make the base for your build so it will be an exact fit. Durabase solutions have many positives compared to the old method of conservatory base building.

The Durabase, once assembled, will create a safe and strong foundation for your building.

The only foundations needed from the Durabase feet are several concrete pads, which we install at specific points around the base. This is so much less excavation work and hardly any waste material to dispose of compared to other methods of base construction. The Durabase System is also super fast to install. We can install an average base and wall in less than two days.

How long does it take to build?

Building your foundation could take just two days, or longer if you opt for a traditional concrete foundation.

Add Frames and Glazing

The next stage is to add the walls and frames for the windows. Careful measurements and accurate work will produce the best results. Once again, the type of extension you choose changes the installation time.

We supply and install the Leka Xi system. Here’s why we love these products:

The Leka Xi is a fast and easier method of building your dream living space. Often in Cornwall & Devon, we find that access to properties may be restricted to larger vehicles, making building works a long drawn-out process because of logistics. However, with the Leka Xi, no heavy excavation is required, this means no heavy digging equipment or tonnes of waste to get in and out of the property.

How long does it take to build?

Walls, frames, and windows can require a week or two for complicated builds. Using the Leka Xi system, we can create a beautiful space with serious wow factor in less than a week.

Complete the Roof

The final building step is the completion of the conservatory roof. If you’ve chosen a style not designed for fast, modular work, then this step could take several days or more than a week to finish. Each frame and area will need careful installation so the building doesn’t leak while in use.

We prefer Ultraroof and Livinroof products for our builds. The installation times are much faster and they are elegant solutions for your house and garden. Here’s why we recommend LivinRoof:

The Livinroof is constructed from high-grade aluminium or insulated composite external panels and insulation. It features a stylish, hard wearing design that gives it a stunning modern look. The urban grey panels that form part of the Livinroof will add that all-important wow factor to your home from the outside.

Inside you have a choice of pelmet sizes that create a stylish feature especially when coupled with LED downlighters and speakers. The plaster finished ceilings frame the strategically placed glass panels and bounce the light into the room.

How long does it take to build?

Depending on the measurements, we can finish this type of conservatory roof in a few hours or a few days. Heavily insulated roofs or traditional styles could take longer.

Finishing the Conservatory

After you complete the other steps, it’s time to finish the job. This might involve laying custom floors, painting any interior walls, and adding fittings such as lights, ceiling fans, or blinds.

This last phase is perhaps the most important time to consult a professional. They know the tips, advice, and things to do to add a beautiful finishing touch to your home.

How long does it take to build?

Depending on the work required, the finishing stage could take a single day or up to a week.

How Long Does It Take to Build a Conservatory?

A small, modular lean-to build could be finished in less than a week. A large extension with a heavy foundation and super-insulated roof could require a month to complete.

Now that you know the process, it’s time to take a positive first step. You can begin by contacting us. Our teams have the experience to guarantee you’ll get the results you have been dreaming of for your home.

Many conservatories can be built without planning permission. However, if you need to secure permission, you should allow for up to eight weeks for your application to be processed.

Yes, you can probably build your conservatory without planning permission. We've written a full conservatory planning permission guide for 2021. You can read it to have all your planning permission questions answered.

Absolutely! We love conservatories so much we are proud of the people who build their own new conservatory. Having said that, our experience, access to professional tools, and partnerships with leading brands might mean we can deliver better results for you.

Simple styles, such as a lean-to, may be within reach of a competent DIY homeowner. Modular installations, like Durabase and Lekia Xi, make the job easier as well. However, professional builders know how to guarantee a conservatory that doesn't leak, retains heat properly, and looks gorgeous.
