Insulated garden rooms from a UK company

Garden Rooms and Home Offices that are fully insulated for year round use. From as little as £10,000

Why should I buy a UK garden room?

Garden rooms are a brilliant way of adding extra space at home without the need for planning permission. Much better than a garden shed or summerhouse which get full of spades and spiders, our garden rooms are fully insulated for use all year round.

The integrated electrics makes it easy to set up a garden room as a place for the kids to hang out, meeting teenage demands easily using with modern technology. Alternatively, you can use it as a relaxation room, reading room, or a place to do yoga, without the noise coming from the family in the background.

Planning guide for UK garden rooms

Domestic garden rooms and offices can usually be installed without the need for planning permission. Providing the building is 2.5m high or less and behind the front line of the house, it should be classed as permitted development. Please note that if you are in AONB locations or have a listed building, the rules may change.

If you require a building taller than 2.5m high, you will need to be 2m from a boundary, or apply for planning permission. Choosing the planning route isn’t always as intimidating as it sounds, however you will need some elevation drawings and some location maps to accompany your application. We can assist you with the elevations and overhead drawings (subject to a £200 fee), whilst the location maps are readily available online, via the links from the planning portal website.


Plan your Garden Room

To get the best out of your additional new space, make sure you plan before you buy. Not only must you plan where it will go in the garden, but it will also help if you plan the layout.

Use the Ikea room planner and add a sofa, bookcase, writing desk and rocking chair. To determine beforehand, just how efficient or inspiring the environment can be, and how you can maximise it’s potential.  It even creates a shopping list for you to buy later.

Here’s where you get to choose the perfect garden room. You could combine a garden office and a shed together, or even split a larger building with a partition and create a kids den and an adult bar, or his and hers garden studios.
