FREQUENTLY ASKED QUESTIONS

Got a question about Cabin Master's garden buildings? See answers to the most commonly asked questions below...

Do I need planning permission for a garden room?

Most garden rooms do not need planning permission as they fall into the 'outbuildings' category. There are certain rules you will need to comply with which include the overall size and height of your building. The majority of homes have permitted development rights for their land but it is worthwhile checking for your home and area. Within permitted development the key rules are as follows:
  • Garden rooms must be single story
  • The building cannot exceed more than 50% of your garden. When calculating the 50% overall you must take into consideration all outbuildings including sheds, and extensions to the original home.
  • It should not be sited on land forward of a wall forming the 'principal elevation' (that means not in front of the house).
  • If the garden room is within 2m of the property boundary the whole building should not be higher than 2.5m

Can you help me design the garden building?

Yes. For our bespoke garden rooms, we work with customers to design garden buildings that suit their vision, space, intended use and other requirements. Our design team will produce FREE 3D designs, so you can visualise your perfect space. This includes factors such as your window and door placement, cladding option, any internal partition walls and your size, built in 10cm increments. 

Will a garden room add value to my property?

Yes, a garden room can add value to your property. It creates extra usable space without the need for a full extension, which is appealing to many buyers. A well-built garden cabin can make your home more versatile and attractive, especially with the growing demand for flexible living and working spaces.

Are your garden rooms insulated?

Yes, our garden rooms are fully lined and insulated. This means that you get a space that maintains a comfortable temperature throughout the whole year. 

What can a garden room be used for?

Our garden rooms are highly versatile and are commonly used as home offices, garden gyms, creative studios, hobby rooms, garden playrooms, mancaves and garden bars.

How much does a garden room cost?

The cost of a garden room can vary quite a bit, as it really depends on what you need and how you plan to use the space. Factors like size, layout, finishes, and optional extras can all influence the final price.

Our outdoor rooms start from £12,500, which includes everything you need to enjoy your new space in next to no time.

How do garden rooms compare to home extensions?

Garden rooms are typically much faster to install, far less disruptive, and more cost-effective than traditional home extensions. 

They also offer greater flexibility, as a garden room can be used for a wide range of purposes, from a home office or gym to a studio or relaxation space, without the complexity and higher costs of extending the main property.

Do you need planning permission for a toilet in a garden room?

Buildings regs can be applied to allow for you to add water and waste to your new garden room and also use the space as a 'livable structure'. Contact our team to find out more.

INSULATED GARDEN CABINS

Modern insulated garden rooms provide a stylish and practical way to add extra living space to your home. Quick to install and often covered by permitted development, they offer a hassle-free alternative to traditional extensions.

Whether you need a home office, gym, hobby room, garden bar or relaxing retreat, a bespoke garden room gives your family the extra space to live, work and unwind.

Advising You At Every Step

On our initial phone call we will establish the size and style of cabin that you are looking for so a 3D drawing can be created.

We'll start with a consultation to discuss your ideal cabin size, style and requirements, before creating a personalised 3D design. We then carry out a site survey to assess your garden and advise on the most suitable base or foundations, whether you're providing them yourself or would like us to handle everything for you.

In most cases, our garden cabins fall within permitted development, but if planning permission is required, our experienced team can provide guidance and support throughout the process.
