Questions & Answers

  • Can I build a granny annexe in my garden?

    You will most likely be given a Lawful Development Certificate from your local council – all you need to do is apply for it! You should have in mind that the granny annexe cannot be used as a primary residence, as it’s one of the conditions of the regulations. You will also need to make sure that the building is not on the edge of the property – you can find out more in our Planning Permission page.

  • Does a granny annexe add value to the property?

    Absolutely. Nowadays, a granny annexe can add between 20-30% extra value to your property in the UK. If you ever plan on selling your property, your proposition will gain more traction and stand out from others thanks to a great offer of a stylish and functional granny annexe.

  • Do you need permission for a granny annexe?

    Usually, Planning Permission is not required for granny annexes, as long as you’re planning to build one in your garden and use it as an additional room. These buildings meet the 1968 Caravan Act requirements because they can legally be viewed as mobile homes – this is why each kit arrives with additional parts which can help move the building. So, you can rest easy once you apply for and receive the Lawful Development Certificate. For more information on this topic, please refer to our Planning Permission page.

  • Do you provide finance options for building a granny annexe?

    In a nutshell, yes, we offer several financing options, so you can build your cabin in time by paying for it over several months. In collaboration with our partners Omni Capital, we offer financing for up to £25,000 of your selected product’s price. The good news doesn’t end there – applying for it only takes a few minutes! You can find our Finance Calculator and answers to other commonly asked questions on our Finance page.

  • How big can a granny annexe be?

    Our biggest granny annexe is BOSTON M – it takes up 114 m2 of space and has a height of around 3 m. This traditional model features numerous multifunctional rooms and a covered terrace. The size is very close to the biggest possible measurements for a granny annexe according to the regulations, and it's designed to suit the needs of a big family and friends. Take a look, and if you have any further questions about this or other models, ring us up at 02070994301!

  • Can I use a granny annexe all year long?

    Most of our granny annexes are suitable to be enjoyed year-round, however, the insulation level depends on which version of the model you decide to go with. Some customers also use electric heaters for added comfort and cosiness. We recommend checking out the extras – PVC windows and doors, a twin skin construction, and others. These additions would guarantee high-quality thermal insulation for year-round use. If you’d like to know about these upgrades in detail and compare the benefits, here’s our Insulation page.

  • Is it difficult to install a granny annexe?

    It depends on which model you pick and the size of it, but it’s not a difficult task for a small group of people – if the model is of an average size, such a group could install it in around a week. It takes a bit longer than usual because we also supply additional parts that would be useful if the building was to be moved to a different place. Of course, if you don’t have time to build the model yourself, you can make use of our professional and efficient assembly service.

  • Can a granny annexe be assembled in a garden that has narrow access?

    One of the benefits of ordering a prefabricated granny annexe from Quick-garden.co.uk is that we use flat-packs for delivering the model kits. This means that as opposed to an assembled model not fitting through the driveway, the model you ordered will come in parts, which can be carried to the assembly place for construction. If you have any additional questions about unloading or hard to reach areas, we have answered them on our Delivery page.

  • Can I modify the layout of the granny annexe?

    Certainly – we’re always excited to hear about your vision and make it come to life, as long as the measurements and the structure are within the regulations. We can check that for you and give you advice on the best plan moving forward, whether it’s by making changes to our standard layouts or creating a new bespoke project. If you’d like to hear more, call us at 02070994301 to discuss all your options.

  • Do you offer bespoke granny annexes?

    We do! You’re free to choose a model you like and decide what adjustments you’d like to make to the bespoke project, including adding a wall to create an additional room, adding a window, and the like. At Quick-garden.co.uk, you can also choose additional features to add as extras to your purchase, e.g. the assembly service, painting, plumbing, and many more. All the extras are on the product pages – you’ll see them beneath each granny annexe. all us at 02070994301 to discuss all your options.
