Wooden conservatories are conservatories that have been built with a wooden structure. If you want a traditional look, you might want to opt for a wooden conservatory rather than an uPVC model.

Hardwood conservatory prices generally fall somewhere between £12,000 to £28,000 for your average hardwood conservatory.

Oak conservatory prices

Oak is one of the most popular wood types used in conservatory construction, and because it is so widely and readily available it can usually be found for as little as £10,000 per extension. Oak is also, however, very strong and can be manufactured to be very bug and pest resistant while maintaining its polished veneer; oak conservatory prices for the most expensive type of oak can often reach as high as £100,000 for a new conservatory.

Timber conservatory prices

Engineered timber usually refers to the different types of wood cheaply available after the trees have been felled but before the wood has been treated in various factories or plants. This type of wood can often be picked up at a discount price because of it’s lack of a clean finish and generally rough exterior, but it is still a strong and sturdy option that can always be treated by you or your team at a lower price. The cost of a timber conservatory will vary depending on the type of wood, but prices usually start anywhere from £30,000 to £45,000.

The type of wood you choose, however, isn’t the only thing that will affect the price of your new conservatory; the size, style and quality of materials for your final conservatory design will affect the final pricing.

A standard, lean-to, uPVC conservatory will cost less, for example, than a large, wooden Edwardian conservatory. You can also make sure you pay less for your conservatory by choosing regular double glazing and simple doors, for example:

  • The cheapest 2.21m x 2.237m conservatory from Direct Conservatories4U costs £1,745

Creating a smaller conservatory might not be the best way to save money because construction costs and legalizing conservatories on house plans raises small conservatory prices a lot more than you might expect.

Small Conservatory costs

Expanding your home (but nothing fancy- double-story or large extension) a conservatory roof might be just the thing you’re looking for. A small conservatory in the range of 2500mm x 3500mm will likely cost between £2,000 and £3,000. Even the smallest of conservatories can improve your property value and is worth the investment and effort. Small conservatories are becoming more popular in smaller units because it is often the only way residents can enjoy sunlight in their homes.

Lean to conservatory prices


A lean to conservatory is usually installed with a basic floor plan of rectangular shape. These conservatories utilize the space well and maximize the sunlight entering the room. Compared to other types, lean to conservatory prices are low. Since there are a number of options available, the costs do vary. Let us take a deeper look at how lean to conservatory cost gets affected?


Lean to conservatory designs are flexible and feature many options; you can select any of these as per your desires. For the base, you have three main choices, which are dwarf walls, full glass models and raised uPVC panels. As for the roof, you can either opt for glass or polycarbonate. Glass allows more light to enter, but polycarbonate is a more affordable option.


A number of features are offered with a lean to conservatory to make it secure and prevent an intrusion. With every feature that you choose, prices will rise. The most common of these are internal beading on the glass, force resistant hinges, multi point locking system for the doors and shot locking mechanism for the windows. You can also opt for toughened glass.

Some installers offer a guarantee with lean to conservatories. This covers the installation value and deposit cost. Failure to comply to building policies must also be included.

How much does a lean to conservatory cost?

The cost of a lean-to conservatory will be largely determined by its size, but generally, you should expect to pay around £10,000 for an average sized version. However, it is possible to build a small lean-to conservatory for as little as £5,000.

How Much Does A Conservatory Size 3×3 Cost?

If you have ever tried purchasing a conservatory, it is very possible that you have gone back home inconclusive of how much a conservatory really costs due to the different prices you got from different sellers. Be rest assured that there are factors contributing to these price differences.

A complete build 3×3 conservatory can cost between £8,000 and £15,000. This rather massive variation is caused by a number of factors ranging from quality to abnormal site conditions to salesmen who only earn from commissions.

In search of a 3×3 conservatory? It is pertinent to know what questions to ask and where to get the valid answers from.

Your 3×3 Conservatory Options:

Firstly, you have to know what you really want. You might think you already do but think about your options.

  • Do you have an already existing conservatory that you want to replace or are you building from ground up?
  • Are you going to employ a conservatory specialist to oversee the project from start to finish or are you going to employ the services of your own builder?
  • Will you employ a fitter to complete the job or will you rather complete it yourself ?

Replacing an existing 3×3 Conservatory

This comes quite easy. You get to choose the kind of roofing material you want and the spots you want your windows.

The cost required to complete a 3×3 conservatory can be kept below £7,000 if you are replacing an existing one except you intend to add extra features that would increase the pleasure you will get from the conservatory.

If you are building from ground up, don’t be too quick to decide that it is a project you can handle by yourself until you have weighed in on the available facts.

At this point, the question, “How much does a 3×3 conservatory cost?” starts to take shape and demand more attention. .

The Cost of 3×3 Conservatory Base

The base work comes first. Observe the house wall that is meant to become the back of your conservatory closely because the presence of obstructions on this wall will definitely affect the cost of your conservatory.

You have to really think about things like garden taps, heating boiling vents, kitchen waste water pipes and rain water downpipes. Underground services, waste water inspection covers and tree roots should also be taken into consideration.

Take note that a 3m×3m Lean-To conservatory (inner measurement) must have a measurement of 3.6 metres as its external width to give room for a double skin wall when the space in your garden is being measured.

The Cost of  3×3 Conservatory Flooring

Working with a budget and trying to manage cost should not leave the insulation of your floor out of the project. It is inexpensive and would help keep your conservatory floor warm in winter. Be sure to have a properly insulated and a smooth concrete finished floor.

You need to have figured out a couple of things before the floor is finished to avoid mistakes that will affect the look of the conservatory. Decide on how many electrical outlets that you want and the cost that will be incurred if a screed finish is required.

3m x 3m Lean-To Conservatory

The kind of flooring you choose for the nine square meter 3×3 Lean-To conservatory floor always has an impact on the cost regardless of the not-very-large appearance the conservatory gives.

During winter, a wood floor tends to be quite attractive and gives warmth to the touch but the cost of buying and installing it is high.

Tiles are very beautiful and relaxing making summer time awesome but the emergence of winter tells a different tale.

Numerous natural floor coverings that look perfect for your conservatory and give warmth are available. Seagrass being the cheapest.

It definitely isn’t the toughest wearing but its price cannot break your account and laying it is quite easy. There is a wide variety of colours and textures that you can choose from.

  • The materials for a lean-to conservatory with dwarf walls will cost between £2,039 and £3,018

  • A three-sided uPVC Edwardian conservatory kit 3.130m in width, 3.119m in height and 3.060m in depth will cost £3,999 from Wickes. This kit includes toughened safety glass, a polycarbonate roof, French doors and a 10-year guarantee.

Of course, these prices are just estimates, and shouldn’t be relied upon except for preliminary budgeting plans; for more accurate DIY conservatory prices, you should contact a number of different retailers and manufacturers to compare product costs and find the best self-build conservatory prices for you.

Final DIY conservatories prices will depend on a variety of different factors, including the height and width of your chosen model, and how long you think the job will ultimately take; erecting a Victorian or Edwardian style conservatory by yourself will take significantly longer than installing an ordinary lean-to conservatory. Nevertheless, you are sure to save a large lump sum on labour costs, and can always haul in a couple of friends to help out if things get on top of you. Just remember – only those proficient in DIY and confident enough to scale a ladder and carry out this type of building work should engage in this type of DIY installation project.
