Cost of a garage conversion, by garage type and size<\/figcaption><\/figure>\n<\/div>\n\n\n

If you have a garage, but hardly use it, a garage conversion could be a great way to make the most of the space you already have. It\u2019s also cheaper than other home expansion projects, such as extensions<\/a> and loft conversions<\/a>, and a garage conversion has the added benefit of not stealing space from your garden either. <\/p>\n\n\n\n

You can turn your existing garage into a bedroom with an ensuite bathroom, convert it into a home office, or even create an open plan kitchen. Garage conversions offer plenty of options. <\/p>\n\n\n\n

A garage conversion can also add a lot of value to your home<\/a>. Depending on what you want to use your new living space for, on average, a home office could add \u00a311,706<\/strong> to the value of your property, while a home gym could add \u00a311,927, <\/strong>and a new dining room and lounge (separate from the kitchen), could add \u00a312,279, <\/strong>making it a valuable home improvement project. <\/p>\n\n\n\n

If you\u2019re thinking of converting your unused garage into a new room for your home, this cost guide covers everything you need to know. <\/p>\n\n\n\n

On average, a garage conversion costs between \u00a318,000 <\/strong>and \u00a328,300.<\/strong> <\/p>\n\n\n\n

Keep in mind that cost of labour is higher in London and the Southeast, sometimes by up to 20% on average.<\/p>\n\n\n\n

The average garage conversion costs between <\/em>\u00a318,000 <\/em><\/strong>and <\/em>\u00a328,300.<\/em><\/strong> <\/p>\n\n\n

How much you end up spending on your garage conversion depends on the type of garage you have (whether it\u2019s an integral garage, an attached garage, or a detached garage). <\/p>\n\n\n

This is because attached and detached garages often require additional structural integrity checks and other building work. The size of your garage will also impact costs.\u202f<\/p>\n\n\n

\n\n
\n\n
\"Picture<\/figure>\n\n\n

Integral garage<\/strong><\/p>\n\n\n

Integral garages are a type of attached garage that are built within the walls of your house and tend to have a door that connects your garage to your home. <\/p>\n\n\n

<\/p>\n\n<\/div>\n\n\n

\n\n
\"Picture<\/figure>\n\n\n

Attached garage<\/strong><\/p>\n\n\n

Attached garages are attached to your home by a shared wall, but also have their own walls and roof that you will need to reinforce during the conversion.  <\/p>\n\n<\/div>\n\n\n

\n\n
\"Picture<\/figure>\n\n\n

Detached garage<\/strong> <\/p>\n\n\n

Detached garages are free standing and are entirely separate from your home. They require the most building work to connect them to your house with new insulated walls, plumbing, and other roof work. <\/p>\n\n<\/div>\n\n<\/div>\n\n\n

<\/div>\n\n\n

A garage conversion includes removing your garage doors to replace them with walls, doors, windows, insulation and heating, electricity, and plumbing. The below prices also include the cost of plastering and painting the walls of your converted garage. <\/p>\n\n\n

We recommend you ask for multiple quotes. Having a good sense of what is included in your package will help you figure out how much you\u2019ll need to budget. Tell us what you have in mind and get some free quotes today.<\/p>\n\n\n

Prices will rise if your garage conversion project requires extensive remodelling of the existing floor space (for instance if you\u2019re converting your garage in order to extend your kitchen). It will also cost more if you want a bathroom suit installed as well.

You may also wish to hire an architect to help you make the most of your space before you hire your skilled tradespeople. Lastly, you might also want to hire a post construction cleaning specialist<\/a> to properly clean your garage and surrounding areas after the building works are finished. <\/p>\n\n\n\n\n\n\n\n\n

How long does a garage conversion take?<\/strong><\/h3>\n\n\n
<\/div>\n\n\n
\"Picture<\/figure>\n\n\n

If your project doesn\u2019t require extensive structural changes or reinforcements, the average garage conversion should take between 3 and 6 weeks to complete.\u202f <\/p>\n\n\n

How long your garage conversion will take depends on: <\/p>\n\n\n

    \n\n
  1. The size of your garage <\/li>\n\n<\/ol>\n\n\n
      \n\n
    1. Structural work involved <\/li>\n\n<\/ol>\n\n\n
        \n\n
      1. How much plumbing and electrics you need installed\u202f <\/li>\n\n<\/ol>\n\n\n
          \n\n
        1. The materials you choose (some require longer to source) <\/li>\n\n<\/ol>\n\n\n
            \n\n
          1. Whether you need to wait for planning permission <\/li>\n\n<\/ol>\n\n\n
              \n\n
            1. How intricate your design idea is <\/li>\n\n<\/ol>\n\n\n

              Some garage conversions can take a little less, such as if you want to use your garage as a bedroom (2 – 4 weeks), whereas projects that require lots of structural changes and plumbing could take between 6 – 8 weeks. <\/p>\n\n\n\n\n\n\n\n\n

              Do you need planning permission to turn a garage into a room?<\/strong><\/h3>\n\n\n
              <\/div>\n\n\n

              Whether or not you will need planning permission to convert your garage depends on the type of garage conversion you\u2019re getting. <\/p>\n\n\n

              You don\u2019t usually need to apply for permission if the project involves internal work (that won\u2019t enlarge your house). <\/p>\n\n\n

              If you\u2019re planning on turning a detached garage into a separate house, then planning permission may be required. You can discuss your proposal with your Local Planning Authority to make sure you have the correct, lawful permission to build. <\/p>\n\n\n

              For more information, visit the Planning Portal website<\/a>. <\/p>\n\n\n\n\n\n\n\n\n

              Do I need an architect for a garage conversion? <\/strong><\/h3>\n\n\n
              <\/div>\n\n\n

              If your garage conversion does fall under Permitted Development, you won\u2019t need an architect to draw up plans for you to submit to your local authority. <\/p>\n\n\n

              However, architects can help you make the most of the space you have and can give you a breakdown of the key considerations for your project, which can then come in handy when you hire your tradespeople.\u202f <\/p>\n\n\n

              If you do need planning permission for your garage conversion, then you will need to hire an architect to supply drawings. This will cost you upwards of \u00a32,000, <\/strong>depending on the scope of your project. <\/p>\n\n\n

              You will also need to hire a structural engineer if you\u2019re planning on building upwards (on top of your garage) as you will need foundations and roof joists. <\/p>\n\n\n\n\n\n\n\n\n

              How to save money on a garage conversion<\/strong><\/h3>\n\n\n
              <\/div>\n\n\n
              \"Picture<\/figure>\n\n\n

              There are plenty of ways you can save money on your garage conversion. Following some of these tips could help you keep costs down, without having to compromise on quality: <\/p>\n\n\n

                \n\n
              1. Ask for multiple quotes<\/strong> before you settle on your tradespeople – it\u2019s a really good idea to know what a project could cost you (upper and lower ranges) so that you can make a properly informed decision about how much you want to spend on your garage conversion. <\/li>\n\n<\/ol>\n\n\n
                  \n\n
                1. If you\u2019re trying to decide what you should save your money on, invest in long-term elements <\/strong>like structural alterations, whilst budgeting on things you can change more easily later on like paint and decorative supplies. <\/li>\n\n<\/ol>\n\n\n
                    \n\n
                  1. If a quote looks too good to be true, then it probably is – always check what is included in your package<\/strong> and remember to consider additional costs and prices that might not have been factored into the original quote. <\/li>\n\n<\/ol>\n\n\n
                      \n\n
                    1. Save money in the right places<\/strong> – not only are the cheapest products more likely to break and need replacing sooner than more sturdy materials, but hiring the right tradespeople is also vital. In the long run, having everything installed correctly the first time can save you a lot of money. Do your research, and make sure you hire skilled tradespeople who will get the job done, right.\u202f <\/li>\n\n<\/ol>\n\n\n
                        \n\n
                      1. Stick to the original design plan <\/strong>– when you start adding additional elements mid-way through the project, costs start to rise and can get out of hand. To keep everything under control, make a plan and then stick to it. <\/li>\n\n<\/ol>\n\n\n

                        Always hire skilled labour – a badly converted garage will only lead to further costs down the line to fix or replace mistakes made during the original build. Find out how much your garage conversion could cost you here. <\/p>\n\n\n

                        If you have a garage that you aren\u2019t using, converting it has a lot of benefits, opening up space in your home, but with much lower costs than other types of extensions and loft conversions. <\/p>\n\n\n\n\n\n

                        Alongside loft conversions, garage conversions are one of the best ways to make the most of the space you already have, without having to build an extension, which is more expensive. <\/p>\n\n\n\n

                        Adding space and value to your home (over \u00a311,000 on average) a garage conversion comes with plenty of benefits. Not to mention that it gives you a lot of creative licence to turn that unused space into a gym, an office, part of your kitchen, or even an ensuite bedroom. <\/p>\n\n\n\n
