    Single Storey Extensions costs

    What is the Average Cost of a Single Storey Extension?

    The average cost of a medium single storey extension is between £24,225 and £37,485 . It’s worth mentioning that the price will fluctuate depending on certain criteria and options including size, style and design.

    You’ll have a lot of choice in terms of colour, finish and hardware options too so it’s a good idea to have plans of how you want your single storey extension to look.

    The average cost of a single storey extension will also change depending on your selection of doors, windows, glazing and materials.

    From French doors to bi-folds, casement windows to tilt and turn, there are a number of possibilities and options to select from. Your installer can talk you through the features and benefits each product brings and recommend the best solution to suit your property.

    Depending on the reason you’re having an extension fitted will impact the way it should be designed.

    For example, if you’re investing in an extension to add an open plan area that is more connected to the garden, it might be that you look at adding bi-fold doors or sliding doors to create an easy transition.

    Alternatively, if you’re looking to create an extension that includes a dining area or kitchen island, you may want to think about adding a roof lantern as a focal point above it which floods the area with natural light.

    Modern single storey extensions often feature a solid roof which results in a traditional extension aesthetic with better privacy and energy efficiency benefits.

    You can then personalise the space to your taste whether you’re going for something more decorative and elegant or something simpler and more minimalist.

    What are the Advantages of a Single Storey Extension?

    Adding a single storey extension to your property can bring with it a number of benefits and advantages. One of these plus points is that it can add value to your home of up to 7%.

    This is particularly attractive to homeowners who are looking to sell their property in the near future as it can add kerb appeal to any home which is a bonus for prospective buyers.

    Your new single storey extension will increase the thermal efficiency of your home with intelligent double glazing that is designed to trap warm air inside your property keeping it warmer for longer.

    In the warmer months it works hard to reduce the heat of the suns glare to maintain a consistent and comfortable environment inside of your home.

    With increased thermal efficiency comes reduced energy bills as you’ll find less of a reliance on central heating.

    As well as this, your carbon footprint will become smaller as you’ll be losing less heat from your property into the atmosphere.

    You’ll also find that draughts are eliminated, and you won’t suffer with issues such as a build up of condensation or water ingress. These benefits come with a professional and efficient installation.

    How Much will it Cost to Install a Small Single Storey Extension?

    If you’re wondering how much it will be to build and install a single storey extension, you’ve come to the right place.

    A single storey extension will cost between £14,535 and £26,775 to build and install. Most conservatory or orangery extensions don’t require planning permission, so you won’t need to worry about any unexpected or extra costs. Your chosen installer will take care of the entire process from beginning to end to make sure that your single storey extension stays within your budget.

    The cost of your single storey extension will depend on your selection of material, size, style, design, doors, windows, glazing and more. Visiting design inspiration galleries will give you an idea of what you want from the space in order to get a detailed idea of what your project will consist of and how much it will be.

    When it comes to the size of your single storey extension you’ll need to think about the space you have available.

    If you’re looking to add a small single storey extension to your home, it might be that you focus more on the finer details to make the most of the area available.

    If it’s to add to an existing room such as the kitchen or living room, it might be that you have specific objectives such as adding more light into the room or creating an area to relax or entertain.

    If you’re looking to add a large single storey extension, again you will need to think about how you want to use the space and what you wish to achieve.

    If the main aim is to connect your home to the garden it might be that you want to create a breakfast bar area, dining or seating area with easy transition with the use of bi-fold doors or patio doors that glide open. You may also want to consider the roof style with vaulted or pitched ceilings to add a sense of grandeur and elegance.

    With a number of styles available you can create a truly bespoke extension solution.

    Choosing the material of your single storey extension is important with options such as uPVC or aluminium each with their own features and benefits.

    Aluminium is a strong and robust material that is also incredibly lightweight, creating slim sightlines and a strong structure that offers durability and security. It makes for a modern and efficient material choice for building and construction with proven flexibility, the fact that it is 100% recyclable and offers minimal maintenance.

    uPVC is also a robust material adding a low maintenance solution to a property as well as excellent thermal efficiency.

    Slightly lower in cost than aluminium, uPVC is budget-friendly as well as durable. Unlike traditional timber, uPVC won’t suffer with rotting, warping or discolouration over time making it an excellent choice for your single storey extension plans.

    It can protect your home against adverse weather conditions, keeping your property watertight and safe. With high insulation properties and a wide range of colour options, uPVC is a highly sought-after material for your single storey extension

    How Much Does a Solid Single Storey Extension Cost?

    A solid single storey extension costs between £14,535 and £72,000 on average. They are popular with homeowners as they provide a new room in your home that can add just as much increased natural light into your home as a glass extension can, whilst maintaining your privacy.

    By adding a lantern roof or skylight, you can flood the extension with natural light to create the illusion of more space.

    A roof lantern acts as a brilliant focal point, drawing the eye and creating an ambience inside the property that the whole family can enjoy.

    Usually positioned over an area where people gather together such as a dining room table, kitchen island or seating area, they are an effective addition that enhances your extension with aesthetic appeal.

    Adding a solid single storey extension to your property can expand the floor plan and update the look and feel of your home.

    Whether you own a conventional property with period features or something more modern with a contemporary feel, an extension can give any home a new lease of life and be tailored to fit with your personal taste.

    You can match your new extension to be in keeping with your current property aesthetic to create a seamless and consistent style.

    Choose from a large number of styles ranging from minimal designs to something more decorative and grand, it’s completely up to you!

    Whether you have a large space available or you want to utilise a smaller area, your single storey extension will be built to your specifications.

    You won’t have to compromise on style over function as you’ll be able to have the best of both worlds with a professionally installed single storey extension.

    You won’t have to worry about your extension being too hot in the summer and too cold in the winter and you’ll be investing in extra space that is usable all year round.

    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.
