Annexes and Extensions: It's All in the Details

Whether attached or detached from the main house, our Annexes and Extensions can accommodate all your living requirements, including toilets, showers, and fully integrated kitchens. Our bespoke designs enable us to work closely with you to create the perfect space for you and your family, considering your specific needs and desires. We even handle planning permission for you, ensuring a smooth and hassle-free process from start to finish!

Our Annexes and Extensions have also been used as extra rooms or accommodations that help pay for themselves. By utilising our buildings, you can take advantage of the increasing popularity of rented rooms from websites like Airbnb when they are unoccupied by family members, creating an additional income stream for your household.

Endless Customisation Options

Let us assist you in making your extended space truly unique and tailored to your individual taste. The design and materials used can be easily customised to your specific needs, ensuring that your new space perfectly suits your requirements. We can customise your new space according to your specifications, including fully-equipped kitchens, luxurious bathrooms, additional insulation for soundproofing, or even bi-folding doors to bring the outdoors in and create an open and airy atmosphere.

Our experienced design team is readily available to offer advice and support throughout the entire process. All you have to do is ask, and we would be delighted to assist you in achieving your vision and creating a space that you will cherish for years to come.

Eco-friendly and Contemporary Bespoke Annexes and Extensions

Vivid Green is committed to constructing eco-friendly Annexes and Extensions that minimise our carbon footprint in numerous ways. By applying the latest technology in modern construction, we utilise Structurally Insulated Panel Systems (SIPS) to maximise the structural and thermal performance of our Garden Spaces, ensuring both efficiency and sustainability in our Annexes and Extensions.

Furthermore, we manufacture all our buildings at our production facility just outside Milton Keynes, which is also adjacent to our main office and newly opened showrooms. One of the key advantages of manufacturing in-house is that we have full control over our projects and processes, enabling us to reduce our carbon footprint by minimising journeys for deliveries to and from our suppliers, ensuring that we are doing our part to protect the environment.

SIPs are one of the most thermally efficient ways to construct buildings. They are made using an OSB board sandwich with a thick polyurethane (PUR) core, resulting in a very low U-value rating. This is why we use SIPs in the floor, walls, and ceilings of our Annexes and Extensions, ensuring there are no cold spots and providing excellent insulation. As the appearance of your new space is of equal importance, we offer a wide variety of finish options to suit your personal preferences and style, allowing you to create a space that truly reflects your taste and personality.

Frequently asked questions

Can I use my building throughout the year?
Our buildings are generally more thermally efficient than an average house. The SIP construction is so well insulated that it will stay cool in the summer and warm in the winter allowing you to use it all year round. They take very little to warm up and consideration is often required to cooling, specifically which you wish to use your building as a gym.
Will my building require any maintenance?
Your building will require no maintenance at all unless you wish to oil your timber cladding. This oiling is not necessary and is a personal preference, but it will help prevent oxidisation, which turns the timber a silvery grey. Other than this though there is no maintenance required. If you want to oil your building we recommend a UV protective oil.
How long will my building take to build?
We cannot give exact install times however we have guideline timelines for buildings of different sizes, see below:
  • Up to 25m2 – 2-3 weeks
  • 25m2 – 45m2 – 2-4 weeks
  • 45m2+ – 3-4 weeks
  • Extensions – 2-4 weeks
  • School projects – 6-8 weeks
Please note that buildings including toilets and showers with service runs, or projects with lots of groundworks may run longer than the above guidelines.
Will my building meet building regulations?
Yes, in every case. Whether a small one man office or a large annexe building, we consider everything and where a building requires inspection and sign off (mainly with larger buildings) we deal with it for you, engaging with the council or an approved building control contractor to provide all required paperwork.
How long after a survey will I get a quote?
We will turn around your quote as soon as possible and aim to do so within 3-5 days. Sometimes we will work on designs with you following the survey, and we will not quote until we have settled on the perfect design so it may be a little longer. However, normally we will have settled on a design on the survey so will not need to go through this process.
