The age-old question – how long will it take for your conservatory to be built? Well, that depends – conservatory builds can actually span from as little as 2 weeks up to 12 weeks, depending on what your build entails, and several other important factors.

What time of year are you building your conservatory – i.e. could a downpour, frost or even snow hold up the timeline? How complex is your build? Have you secured the appropriate planning permission ahead of time?

These are just some of the components that come into play when trying to predict a conservatory build time, which is why we’re here to help you work it all out. 

This guide highlights the estimated conservatory build times by type, the factors that can influence your schedule and the best ways to keep your project on track.

Estimated Conservatory Build Time By Type

Below, we’ve listed an approximate guide to how long common conservatory types take to complete. However, it’s good to note that timelines will vary depending on groundwork, materials, design complexity and weather conditions – but this table gives a general starting point:

Conservatory Style	Estimated Build Time	Why This Timeframe?
Lean-to Conservatory	2-4 weeks	Simple, rectangular design with straightforward roofline and minimal structural alterations makes it quick to assemble.
Victorian Conservatory	4-8 weeks	Multi-faceted bay front and ornate styling require more complex framework and roof construction.
Edwardian Conservatory	4-8 weeks	Square/rectangular layout is simpler, but the pitched roof and larger glazing areas add to installation time.
Gable-front Conservatory	6-10 weeks	The tall, triangular gable frame and more intricate roof structure add extra engineering and installation steps.
P-shaped/L-shaped Conservatory	8-12 weeks	Combining multiple conservatory shapes increases groundwork, structural support and roof complexity.
Orangery-style Conservatory	8-12+ weeks	Requires deeper foundations, brick or stone pillars and a more substantial roof system with lanterns or flat roofs.
Fully Bespoke Conservatory	10-14+ weeks	Custom fabrication, tailored engineering and unique layouts extend manufacturing and installation timelines.

Factors That Influence How Long a Conservatory Build Can Take

1. Design & Consultation

Before any work can begin, the design and consultation stage needs to take place. This is where you discuss sizes, frame styles, roofing options, glazing choices and any special features you want to include. The clearer your vision, the smoother this stage will be.

Typically, this stage can take a few days to a couple of weeks, depending on how quickly decisions are made and how many revisions are required.

2. Materials

The materials you choose – such as uPVC, aluminium or timber – can also affect your timeline. 

Standard uPVC frames may be available quickly, while aluminium or custom-coloured frames could add extra manufacturing time – but how quickly it takes to build shouldn’t be the deciding factor of these materials, as durability, usability and longevity are also important factors to consider. 

As well as your frame materials, unique glazing types or specialist roofing materials can also create delays. Here at West Midlands Double Glazing, we’ll keep you updated on lead times so you know what to expect.

3. Complexity & Style

How complex your conservatory requirements are will also determine your build time. For example, a simple lean-to conservatory will naturally go up much faster than a large P-shaped or gable-fronted structure. 

More intricate rooflines, bespoke features and integrated heating or lighting systems all increase the build duration. In short, the more complex the design, the more tradespeople may be involved, which can extend timelines.

4. Groundwork

Ground preparation, including digging foundations and ensuring proper drainage, can significantly impact build times. That’s why unexpected issues, such as poor soil quality or the discovery of old pipes or tree roots, may require additional work, extending the timeline of your build.

It’s crucial that groundwork preparation is completed properly to prevent issues later on, so it’s worth allowing adequate time for this stage.

5. Planning Permission

Not all conservatories require planning permission, but when they do, the approval wait can add several weeks, so you’ll want to get your application in fast.

The application process typically takes 6–8 weeks, depending on your local authority. Applying early – or opting for a design that falls under permitted development – can help reduce these delays.

6. Bespoke Vs Standard

Choosing a standard size and layout usually speeds things up, as many components are pre-manufactured. Bespoke conservatories, however, often require custom engineering, specialist fabrication, and additional surveying.

If you’re aiming for something unique that reflects your personality, character and existing home architecture, expect a longer timeline – but also a more personalised end result.

7. Roof Type

The roof is one of the biggest contributors to a conservatory’s build duration. 

Glass or polycarbonate conservatory roofs are typically faster to install, while solid tiled roofs or lantern roofs generally involve more structural work.

Special roof shapes, such as gable or double-hipped designs, can also extend the installation period.

8. Weather

And the unpredictability of British weather can also put a stopper in your timeline, too. 

Bad weather, such as rain, frost, snow or sleet, can delay groundwork, roofing and other exterior tasks, which makes winter builds trickier with more unpredictable conditions and shorter daylight hours.

While experienced installers plan around weather patterns, certain stages simply can’t be rushed for safety and quality reasons.

9. Access to Your Property

Limited access – such as narrow side passages or no rear entrance – can significantly slow down the delivery of materials and equipment. Installers may need extra planning or alternative tools to accommodate tight spaces.

In short, good access means quicker, simpler construction – but, as a homeowner, this is often not something you can change! Instead, be sure to account for this time in your expected build timeline.

10. Availability of Tradespeople

Electricians, plasterers and other specialists may be needed at various stages. If they’re in high demand (especially during summer), this can push back your schedule.

However, a company that coordinates all trades in-house will typically avoid these delays.

Here at West Midlands Double Glazing, we pride ourselves on our wide range of availability, helping as many people as we can achieve the home improvements of their dreams in the quickest timeline possible.

How to Speed Up Your Timeline on a Conservatory Build

Planning Permission: Seek Approval Early

If your build requires planning permission, applying early is one of the best ways to avoid project delays. Your installer can often help prepare drawings and documentation to simplify the process.

Getting this out of the way up front ensures the build can start the moment approval comes through.

Preparation: Get Your Space Ready

Make sure the area where your conservatory will sit is free from clutter, debris or garden furniture. If any trees or shrubs need removing, be sure to take care of this well in advance.

Having a clear workspace speeds up the first stages of the project and ensures contractors can get started without disruption.

Clear Communication: Make Decisions Early

Another key way to prevent delays is to finalise your design decisions early. Changing your mind about glazing, roof style or layout midway through the process can push the entire project back.

Staying decisive and keeping communication open with your installer ensures everything moves smoothly.

Choosing a Reputable Home Improvements Company

Working with a trusted and experienced company, like West Midlands Double Glazing, means you’ll benefit from organised project management, reliable tradespeople and accurate timelines. 

We will guide you through every stage and anticipate any potential delays, giving you peace of mind and ensuring your conservatory is built to the highest standard.

How Disruptive Will a Conservatory Build Be?

We get it – nobody wants to be living on a building site for longer than they need to. But, good news – most conservatory builds cause minimal disruption, especially compared to larger home extensions. 

There will be some noise during groundwork and construction, and you may have contractors on-site for several weeks. However, most work takes place outdoors, so daily life in your home won’t be heavily impacted.

A good installer, like WMDG, will aim to keep the area tidy, update you regularly and ensure the process is as smooth and stress-free as possible. Once the conservatory is up, interior finishing is usually quick, meaning you’ll be enjoying your new space before you know it.
