Our Happy Customers

"The team are excellent. From the initial engagement to completing the work the whole process has been smooth and very professional. All of the team that were on site were extremely courteous and professional in their work. Having had bad experience with builders previously I can honestly say the team are fantastic. Would recommend their work thoroughly. The additional gym/workout room they have built for me is beautiful and an investment well made."

Chirag K

"Couldn't recommend the team enough! Perfect experience from beginning to end and they were able to deliver some very bespoke requests which was extremely valuable.

The end product was spot on and not surprising given the care and attention displayed throughout by the team, delivered in the smoothest possible way."

David Lankester

"CHRISTMAS COME EARLY!

Thank you so much for my new garden room, kids back from uni and we need the space! Fantastic service, quick installation and a great finish. The air conditioning that blows hot and cold is fantastic, the insulated walls keep the heat in when you need it. Room for the family as a chill out space we all sooo wanted. Thanks again - a well needed retreat as a pre xmas treat!"

How It Works – Our Simple Process

1.

Enquiry & Requirements

We’ll begin with a no-obligation call to discuss your needs and answer questions. If you’re happy, we’ll provide an initial quote.

2.

Site Visit & Planning

Next, a site visit will assess conditions and access. Planning experts will handle permissions and ensure legal compliance to prevent future issues.

3.

Final Quote and Ordering

After the site visit, we’ll send a final quote. If you’re happy to proceed, a deposit secures your booking and build date, and steel frame production will begin.

4.

The Delivery & Build

We’ll begin with foundation work, typically using ground screws for speed and cost efficiency. Then, the steel frame will be delivered and assembled, with regular updates throughout.

5.

The Aftercare Process

We offer ongoing support after the build, with a dedicated team ready to help. Our quality workmanship ensures your garden room stays a valuable, lasting asset.

Have A Question?

What is the difference between a Garden Room and an Annexe?

A Garden Room is typically a separate building from your main property, situated in the garden. It can have different functions, such as entertaining, use as an office or as a gym. It will usually have features to withstand weather conditions and for all-year-round use, such as double-glazing and insulation. However, it is not self-contained accommodation.

A Garden Annexe (sometimes referred to as a Granny annexe) provides additional living space and is self-contained. This means it has a fully equipped kitchen, bathroom and one or more bedrooms. They are often designed for older family members, hence the term ‘Granny annexe’, and offer independence whilst also being close to the rest of the family. However, garden annexes are not only suitable for elderly relatives but can also be an ideal solution for providing adult children with cost effective accommodation or comfortable surroundings with all the mod-cons for guests.

Does my building come with a guarantee or warranty?

All our buildings come with a 30-year structural warranty.

Can I design my own garden annexe or room?

Yes, you can either chose from one of our designs or create your own.

What type of foundations are used?

Ground screws are used for the foundation unless there is already concrete in place. The ground screws are fully compliant with building control standards and are far quicker to install than traditional footings.

My garden has limited access. Will this be a problem?

One of the first steps will be to conduct a site survey. This will allow us to check if there will be issues with accessing the site. We can then find a solution which will work for everyone.

Do I need a site visit?

We will need to visit the site to ensure we have a clear understanding of the location for the build, and identify any issues which may arise, such as accessibility or the need for additional equipment.

Do I need Planning Permission to build an annexe in the garden?

Our garden annexes typically qualify under the Caravan Act. So, in most cases, you won’t need planning permission. The Caravan Act outlines the specifications of a building which is considered to be mobile. If you chose to design a bespoke building, it may not fall under the Caravan Act. However, we will handle this process on your behalf, keeping you updated at each step of the process.

Why do you use light gauge steel frames?

There are many benefits to using Light Gauge Steel compared to the more traditional construction methods of wood or concrete. These include:

  • Durability - Light Gauge Steel construction offers superior strength and durability compared to traditional wood or concrete construction methods. It is moisture and pest resistant and can withstand challenging weather conditions. Importantly, this means there will be no cracking or long-term movement from loss of moisture that you might typically find with traditional methods of construction.

  • Efficiency - Light Gauge Steel is extremely strong and lightweight (weighing up to 40% less than wood). Also, due to its superior strength relative to wood, less is needed for construction, resulting in up to 50% faster build times and increased efficiency.  It can also be erected in wet conditions, resulting in fewer delays whilst providing consistent quality and accuracy.

  • Versatility - Light Gauge Steel offers exceptional flexibility, allowing for easy modifications and customisation to meet a variety of design needs. It reduces foundation requirements by approximately 2.5 times, therefore meaning costs will be reduced too.

  • Cost - Steel frame buildings offer a more cost-efficient method of construction to traditional brick or timber construction methods. Steel frame buildings are fast to produce, are fabricated off-site and are much faster to erect with less wastage and provide a more environmentally friendly frame than both timber and concrete as it can be recycled. The lightweight properties of light gauge steel frames allow for easy transportation and handling, which provides extra cost savings. It is precise to +/- 1mm per 10m, meaning there is very minimal waste during construction.

  • Sustainability - Buildings constructed using LGS are healthier, more energy efficient and enable more sustainable living for the life of the building. It is a sustainable material that can be infinitely recycled and reused. Steel from old buildings, cars and industrial machinery is collected and processed, reducing the need for mining and the associated carbon emissions.
