    Changing Conservatory to Extension

    Are you thinking of changing conservatory to extension? Are you wondering whether you should convert conservatory to extension? If you are thinking of changing your conservatory to an extension, then there are a few steps you must consider first.

Homeowners usually opt for a single storey house extension; however, they can be made into a double storey if required. Replacing conservatory with extension is a more cost effective way to add value to your home and to extend your existing property. Homeowners may choose a conservatory conversion to extension due to a growing family or want to add value to their property for future selling.

    When you replace conservatory with extension, you get a subtle “extended” element in your home. Whereas, a conservatory is usually noticeably an extra addition.

    Replacing Conservatory with Extension

    You can convert a conservatory to an extension. The way you do this is highly dependant on how much you wish to pay and what you wish to change.

    What are the Options for Changing Conservatory to Extension?

    There are a variety of options available to replace conservatory with extension, depending on what you require upgrading. You may only wish to replace your glazing or roof as opposed to replacing the entire conservatory structure. However, if you do convert conservatory to extension, it’s advisable to consider a full build.

    How Much of your Conservatory Do you Wish to Change?

    If you wish to re-glaze your conservatory, you may opt for replacing the glass panels with a brick conservatory to enhance the thermal efficiency in your home. Replacing the conservatory roof is another way of improving issues with a conservatory, in a costlier manner. Replacing conservatory with extension is another way to resolve the problems you are having with your old conservatory.

    When is it Time for a Conservatory Conversion to Extension?

    When it is time to convert conservatory to extension, there are several attributes that you will notice. It is important to maintain your conservatory over time, which will prevent the need to replace it before the expected lifespan. However, a conservatory conversion to extension can provide you with a larger living space that does not need as much maintenance over time.


    Recognising the outside temperature more is one of the most obvious ways to know your conservatory is not performing the way it should. Latest technologies keep conservatories cooler in the summer by reflecting the heat away. Whereas older, outdated conservatories weren’t built this way, and over time you may find your conservatory is extra hot in summer and even colder in the winter.

    Thermal Efficiency

    Having significantly higher energy costs than in previous years is another way you will notice you could benefit from replacing conservatory with extension.

    On-Trend Colours

    When the time comes that you wish to sell your property, you may want to keep your home up with the latest trends. This may involve changing colours of your conservatory to suit your home better to make your conservatory more appealing. A way of doing this is to convert your conservatory to an extension or a brick conservatory with a tiled roof.

    Benefits of Replacing Conservatory with Extension

    There are a vast number of reasons as to why homeowners may opt to convert conservatory to extension:

    Add Value to your Home

    An extension can add far more value to your home than a conservatory. Whether you are opting to add a new kitchen extension or dining area in a single storey extension. Getting a conservatory conversion to extension is guaranteed to boost the value of your home.

    Warmer Home

    Due to the more insulating layers that an extension offers, you will benefit from a warmer home when you replace conservatory with extension.

    Further to stronger, thicker insulating layers involved when you convert conservatory to extension, you will also find that you will benefit from more noise reduction.

    Larger Living Space

    A conservatory is made to feel like an additional room in your home but is usually separated by internal doors to help keep the heat inside your home. Whereas, when you convert a conservatory to an extension, you’ll have more design choices. Whether you wish for it to be an extended kitchen extension or as more of an orangery extension.

    Two Storeys

    Frequently Asked Conservatory Questions

    In most instances the council tax will not increase on a property unless the additions another living quarter or self-contained annex. This means the addition of a conservatory should not increase the council tax payable on a property. To be absolutely certain you can always check the government's website which gives advice on council tax.
    The main difference between a conservatory and an orangery is how the roof is constructed. A conservatory roof is over 75% glazed whereas an orangery roof has less than this amount. A conservatory also has over half of its wall space glazed whereas an orangery can include more brickwork than this.
    Yes, you can put a conservatory on the front of your house. This is because conservatories come under the category of a permitted development. As such in most instances you do not need planning permission. This applies if the area surrounding the original house is not more than 50% covered by other buildings or additions.
    There are many ways of gaining temperature control. Conservatory blinds, ventilating windows, cooling film and air conditioning to name a few. You might also want to consider replacing your conservatory roof with a tiled or solid design.
    There are many ways of keeping your conservatory warm in the Winter. If you have a small conservatory then an electric heater will suffice but those with bigger conservatories may want to look into installing underfloor heating.
    Glazing is also very important in a conservatory. Most heat can be lost through glass so ensure your conservatory glazing is thermally efficient. You can also tackle draughts or cold spots by installing conservatory blinds.
    This will largely depend on your location. You will find that certain areas have different setbacks based on the use of the building. We recommend that you check with your local council or take a look at the Goverment's Planning Portal.

    You must notify your neighbour if you want to:

    - Build on or at the boundary of your 2 properties - Work on an existing party wall or party structure - Dig below and near to the foundation level of their property
    Replacing your conservatory roof can indeed make your conservatory warmer however, this will depend on the type of roof you choose. A solid or tiled conservatory roof will offer greater insulation than a plastic or glazed roof.
    A solid roof can be put on a conservatory. There are many solid conservatory roof designs available - just ask your chosen installer for a recommendation. The majority of new-build conservatories with a solid, tiled or glazed roof will not require planning permission. They are covered under what is known as 'permitted development'. However, building regulations will apply if you want to build an extension.
    When it comes to your home improvement, it's important to have all the necessary legal documentation. The installation of a conservatory, orangery or porch does not require a FENSA registration form.
    The average life span of a uPVC conservatory is largely dependent on the quality of materials and build. Typically, a uPVC frame can last up to 25 years but some can last for decades ensuring they are well maintained.
    Planning permissions used to say that a certain percentage of roofing must be translucent in order for a conservatory to be exempt from planning permission. Changes to building regulations however, now means that you may not require planning permission for roof replacement.
    Swapping your existing conservarory roof for a tiled or solid roof replacement can be done without needing to file for planning permission. Planning permission may be required however, if the height of your extension is changed following completion.
    A conservatory is defined as a 'building that has no less than 75% of its roof area made of translucent material and no less than 50% of its total wall area made of glass.
    It is possible to convert a conservatory to an orangery but it isn't a simple process. A surveyor will need to come out and assess your property and conservatory to see if it is at first , feasible.
    Both extensions and orangeries often require planning permission and in order to satisfy requirements, a new structure will have to be built.
    If a conservatory is within two metres of a boundary, a conservatory should not be higher than three metres. It must also not extend beyond the rear wall of the original house by more than 3m if an attached house or by 4m if a detached house.
    For construction work to begin a trench will need to be excavated to a minimum depth of 600mm. A conservatory needs footings just as much as any extension does.
    Solid ground will need to found first and needs to be accepted by Building Control as being a minimum of 1 metre in standard conditions.
    Foundations will need to be dug and because conservatories are lightweight in structure, their foundation loads are usually quite low. This can often lead to the notion that shallow foundations are satisfactory however, shallow foundations are more susceptible to subsidence.

    Conservatories that are built with foundations shallower than the Building Regulations advise, are likely to encounter problems.

    Building Regulations state:

    A2. The building shall be constructed so that ground movement caused by :-
    (a) swelling, shrinkage or freezing of the subsoil; or
    (b) land-slip or subsidence (other than subsidence arising from shrinkage), in so far as the risk can be reasonably foreseen, will not impair the stability of any part of the building
    Usually, there are no planning requirements when it comes to building a conservatory to a bungalow. However, the conservatory will be subject to certain conditions so be sure to check with your local building authority or with the Government's Planning Portal to ensure your conservatory remains within these guidelines.
    On average, an orangery can cost anything from £10,000 to £20,000. It is likely to cost double the amount of a conservatory, however it's important to note that an orangery provides more functionality and home value when compared to standard glazed conservatory.
    An orangery allows you to benefit from both conservatory and extension, being a combination of the two.
    When is a conservatory not a conservatory? In order for a structure to remain a permitted development (a conservatory), the build needs to comply with a number of rules. A conservatory must be ground level, must not be more than 30m2, must be thermally separated from the original building, have its own heating and have glazing in critical zones that meet Part Nof the building regulations.
    An extension refers to an additional structure that is anatomically in-keeping with your main property. An extension often requires planning permission unless it is classified as permitted development and is built with opaque cavity walls and brick-based foundations. Extensions are a big home improvement and investment, needing the work of an architect.
    Conservatories or glazed extensions are perfect for those looking to add extra space on a budget. Typically, they are less of a logistical strain and in most cases do not require planning permission,
    A conservatory can be built under permitted development rights, not needing an application for planning permission. A conservatory however is subject to the limits and conditions listed here. Building a conservatory onto an extension however, will be subject to different conditions. In some cases and under the permitted development regulations, you cannot attach an extension to an already extended part of a dwelling. It has to be attached to the original walls of the dwelling house.
    Conservatories are generally much cheaper than a single-storey extension of the same size. The price difference will largely depend on size and how complex the structure is to build, as well as the quality of materials.
    The cost of a conservatory extension can range from £6,000 to £20,000. Compared to a full on extension, it is a much more affordable way of increasing space within your property. A full blown extension can cost up to £30,000. An extension is priced on average, per square metre.
    A conservatory or single-story extension can be built without planning permission if: It's a maximum of 4 metres high or 3 metres high, within 2 metres of a boundary and the conservatory or extension does not cover more than half of the garden.
    From now until 2019, you can extend outwards by up to 8 metres for detached homes and 6 metres for other property types. For this, instead of applying for planning permission you will need to undergo a Neighbour Consultation Scheme.
    In most circumstances, building regulations tend to apply when you build a new extension or a very large structure to your property. However, most of the time, conservatories are exempt from building regulations when they are erected at ground level and the floor surface areas is less than 30 square metres.
    The average life expectancy of a conservatory depends on the quality of materials used as well as the installer. Generally speaking a conservatory built with uPVC window and door frames can last up to 25 - 30 years.
    Conservatory extension costs are far more affordable than a full-blown extension. A conservatory costs anything starting from £3,000 - £4,000 deadening on final styles and specifications. On the other hand, full build house extensions can cost anything from £20,000 right up to £100,000+! Generally speaking extensions are priced on average, per square metre.
    It is possible to build either a conservatory or a single-storey extension without gaining planning permission if: firstly, it has a maximum height of 4 metres or 3 metres high if situated within 2 metres of an existing boundary. The conservatory itself does not exceed over half the size of the garden.
    Yes you can! Whatever the shape of your existing conservatory, you can be sure that there is a solid roof equivalent to meet your exacting requirements.
    Changing roofs from a polycarbonate to a solid roof means that building regulations will apply. Your chosen installer will be able to answer any questions you have and help with any red tape such as contacting local authorities to resolve building regulations compliance.
