Creating a garden room is the modern alternative to large-scale extensions, because they are less intrusive and far more affordable. Creating a separate room in the garden gives you a great getaway for work, hobbies, or just some peace and quiet. If you have questions arbout how to build a garden room, look no further – we have it covered.
‘If you are considering sacrificing some of your garden or outdoor space for a garden room make sure you have really considered how and when you will want to use it’ advises Jo van Riemsdijk at Modulr Space. ‘Any garden room should be an extension of your living space as opposed to subsequent to it.’
Here’s everything you need to know about planning, costing and building the garden room of your dreams.
What is a garden room?
By definition, a garden room is a glazed extension with a fully tiled roof. Garden rooms can either be freestanding, which is a popular choice for home offices, or attached to an existing building. ‘More people now choose a garden room rather than a conservatory, since their solid roof construction makes them highly suitable for year-round living,’ says David Salisbury of David Salisbury Joinery.

When planning a garden room, think carefully about how you’d like to use the space. A garden room can be an extra sitting room, a peaceful sanctuary for enjoying your garden all year round, or a home office or ‘quiet zone.’
The simplest cabin or summer house is similar to a shed, with either shiplap walls and cedar roof shingles or a log-cabin construction. These are usually supplied in pre-fabricated panels and, if you’re a skilled DIYer, you could put one up yourself.
More advanced garden room designs, with sliding glass doors or a deck, for example, will need to be built on site by a specialist. Once the concrete base or piles are in, installation can take from one day to two weeks.
Do you need planning permission for a garden room?
f your building is away from the house, takes up less than 50 per cent of the garden and is smaller than 15 sq m, or in some cases 30 sq m, you’re unlikely to need planning permission or Building Regulations Approval. However, there are exceptions – such as if you intend to use the room for sleeping – so check online at www.planningportal.gov.uk, and consult your local council’s planning department.
‘Most garden room suppliers make the statement that their structures fall within permitted development. However, there are some exceptions to this’ warns Jo at Modulr Space. ‘These include Location within conservation area; location within the curtilage of a listed building; location within a national park or area of outstanding natural beauty. And where a highway/footpath is located beyond a garden boundary’
‘The Permitted Development rights which would ordinarily allow detached garden buildings only apply to gardens of single dwellings. And therefore communal or gardens belonging to flats are unlikely to qualify.’
‘In addition, the use of any garden building is restricted to purposes ‘incidental to the enjoyment of a dwelling house’ – essentially household only use’ Jo explains. ‘Permitted Development rights can also be removed by local orders or by other planning restrictions which may have been imposed on previous planning permissions.’
Choose a garden room company who cover the planning issues. ‘Modulr Space Ltd is run by Architects with experience in planning law. We also work with a Planning Consultant who is able to assist with more complex planning matters and is able to help homeowners get hold of a Certification for Lawful Development Certificate.’
Can I use a garden room all year round?
To maximise the potential of your garden build all year round you should look for a design that is well insulated. If your garden room is insulate well and fit double-glazed windows, you’ll be fine to still use it for the colder months.
An electrician can run a cable from your house to the room to power lights and heating to ensure the space is useable throughout the darker, colder months. In some cases, downlighters, sockets and wiring may be pre-installed in the panel walls.
How to use a garden room?
How you use a garden room depends on the build, as to whether or not you run electrics to a new garden building or simply upgrade the shed. Throughout the pandemic the requirements of garden rooms for home offices and gyms have been the primary purpose. (about)
Are you considering using your garden room as a home gym? Jo at Modulr Space advises, ‘Talk to your supplier about whether you might need a reinforced flooring system. Some units are created from SIPS panels and a dropped heavy weight on the floor could damage the structure.’
‘You should consider head height. Will you be able to use the room as a gym or will you need to go for an increased height if you are tall? Remember that permitted development allows for 2.5 meters in height on a boundary moving to 4 meters at the peak of a roof if the unit is 2 meters away from any boundary.’ Expensive gym equipment can be an investment, so ensure your security is up to scratch.
