Typical 40 SQ/M Extension - Render

10m wide x 4m deep (40 SQ/M)

This material whilst attractive can also be considered as an alternative to the more expensive options available should there be side, or other elevations that will not be seen and therefore not require architectural enhancement. The robust nature of this material cannot be overstated in terms of garden rooms and will last lifetimes without the need for any maintenance. Adding both thermal & sound resistance to the building, with this exceptional material, both style and functionality are thoroughly enhanced.

This garden room's standard 3m x 3m and 4m x 3m footprint maximises your available space without compromising on usability and loss of garden space. The wide range of external finishes that are available mean you can create your own aesthetic to suit your surroundings, all of which exude clean, stylish lines and modern flair to enhance your outside space.

Our standard model incorporates an elegant slim-profile UPVC single hung door and full height openable window; however, sliding and bi-folding options in aluminium and any colour are also available.

What Our Customers Say About Us

I’ve been looking to build a quality garden annex for some time but never found a company to fit our very specific requirements within a reasonable budget. The guys at Vita Modular took on the challenge and went above and beyond to accommodate us. We’re so pleased with the result.

Frederique Shaw (London)

By far this has been the best experience we have had with any work we have ever had done to any house we have lived in. The innovation is great, the way the back office team have dealt with us was kind and professional, and the way the onsite team have worked has been exceptional. What a lovely team. The results have changed the way we use the house in a very positive way. Thank you to everyone.

Derek Mclean (Cirencester)

Delighted with our extension! We wanted to move our utility room so that we could open the back of the house to the garden, and were let down by an architect and numerous traditional builders (frankly we think our project was just too "small" to keep their interest) . Subsequently we started searching for alternative methods and modular builds, and feel like we struck gold with Vita Modular. The team remained enthusiastic from start to finish, and worked with us creatively to make the build happen on a tight budget. The budget was meticulously calculated and kept track of, so that once we started we knew exactly where we stood with costs. We're still amazed how quickly the extension went up! As a bonus, without the need for concrete lorries and brick deliveries, the restricted access to the back of our house was never an issue. The team helped us with the structural changes required in the existing rooms and installed a new large picture window and sliding doors that open onto the garden (beautiful quality aluminium frame double glazing). We're still currently decorating and landscaping, but the extension has already made a huge difference to our enjoyment of the house and garden. Our only regret is that we didn't find Vita Modular sooner.

Planning permission is not normally required as our garden buildings fall under permitted development. Most houses, even in conservation areas and areas of outstanding natural beauty (AONB), have permitted development rights. Flats and listed buildings have no permitted development rights, so will always need planning permission.  Please see the link to the government website below. Don’t worry though, if you do require planning permission we can arrange this for you as part our bespoke turn-key solution.
Can I have a toilet and/or kitchen in my garden building?
Yes we can install a toilet and kitchen in your garden room without any issue at all although this will typically require building regulations approval. We can organise this for you as part of our turn-key solution please speak to us for more information.
Are your garden rooms warm enough to use in winter?
Yes, all of our garden room are designed to current building regulations and therefore are perfectly suited to be used all year round unlike most conservatories or orangeries.
