    Frequently Asked Conservatory Questions

    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
    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.
    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.
