Insulated Garden Office | Year-Round Garden Offices

Insulated Garden Office

Adding an insulated garden office to your home is a practical investment to create extra space for whatever you might need. Warm in winter, cool in summer, breathable and watertight – all of our garden office buildings are fully insulated as standard, giving you the freedom to comfortably work from home all-year-round.

Even though our buildings are named ‘garden offices’, and that is the most popular use by our customers, they can be used for anything you can think of – so don’t be limited!

For this blog we talk about insulated garden offices as the use of a garden office – but the facts remain true no matter how you use your building!

What is an insulated garden office?

An insulated garden office is a quality manufactured building that is completely detached from the home and built using the same premium grade materials used in modern houses. This creates a detached space that is effectively an extension to your home, and as a result, is completely comfortable to use in any season.

Benefits of an insulated garden office:

  • Work all year-round.

    An insulated garden office lets you work from home all-year-round, keeping productivity high no matter what the weather. You might think that a garden office would only be a great place to work in the summer (being out in the garden and all), but the colder winter months are completely held off by our complex insulation layers and heating – keeping you comfortable inside whilst offering gorgeous winter views.

  • Free from the distractions of home.

    Having an office that is completely detached from the main house gives you freedom from the noises, stresses and day-to-day distractions of the home. This means that when you at in the office you can completely focus on the task at hand.


  • A professional space

    A detached office in the garden can be a more professional workspace that a room in your home. As a private room away from the noise and distractions of the house, you can have a video conference in peace knowing you can’t be disturbed by a barking dog, playing child or ringing doorbell. What’s more, if your business means clients may need to drop by from time to time, it is much more professional to the keep your home and work life separate.


  • Work-life balance.

    With your office being detached and away at the end of the garden, it is much easier to keep your home and work life separate. Keeping a distinction between these two sides of your life is good for the whole family and not just for you.


  • Better value than renting office space.

    Renting office space has a lot of costs involved, with your rent payments ultimately amounting to nothing as far as investment goes. By adding a quality built garden office building to your home you are adding value as extra useable space. What’s more, in not too long at all you will have made the money back to pay for your building in what you could have spent in rent.


  • An adaptable addition to your home.

    A garden office building is a completely flexible space. What is your garden office Monday to Friday could easily become a cinema room to use over the weekend – we’ve seen it done many times before! Make the most of your garden office by creating a multi-purpose space.

  • 30-second commute.

    Having an insulated garden office saves you time and money in your commute too – not to mention the benefits to the environment!
    In the winter is when we feel the benefit, with an insulated garden office building taking the pressure away from rainy, icy or dark driving conditions that can sometimes make it hard to get out of bed.

What makes our garden offices comfortable to use all year round?

Insulated throughout

Our walls, roofs and floors are all fully insulated to keep the outside elements at bay and the internal environment warm and comfortable. We have reflective and directional layers in our walls which reflect excess heat from outside, keep internal heat inside and pull away internal moisture. See more about our building construction here…

Breathable design

The construction of our buildings allows for vapour to pass through from the inside of the building, outside – keeping the internal space dry, healthy and free from dampness.


Premium double glazing

The doors and windows in our buildings are fitted with Pilkington k opti-white double glazing. This premium grade double glazing is also fitted with a planiterm layer and swisspacer for optimal thermal efficiency.

Epoxy resin roof

Our steel and epoxy resin roofs are completely maintenance-free as well as being fully insulated. The roof is completely water-resistant and is incredibly strong – able to hold 220kg of weight per square metre which makes them perfect for heavy snow conditions.

Heating included

Every building from The Garden Office comes with an oil-filled free-standing radiator as standard included in the price. As you would inside your home, when temperatures outside start to drop the internal space will need a helping hand to take the edge off. We also have multiple heating upgrade options including wall-mounted radiators and underfloor heating.


Air-conditioning available

For complete temperature control, we offer a range of air-conditioning units as an optional extra. To get the complete professional office environment, air-conditioning is a must!
