Has spending more time at home has made you feel like there just isn’t enough space? Perhaps you’d like studio space, a spare bedroom or somewhere to evict the children when they’re driving you mad? Whatever the reason for the extra space, a garden room may well be the perfect solution! Here we explore some things you should know about erecting a garden room!

Will I Need Planning Permission When Getting a Garden Room?

Generally speaking, you will need to apply for Planning Permission if you intend to use the new space as accommodation and also if you want to exceed the 2.5m height limit allowed under Permitted Development. Every council is different but usually, you can expect this to take up to 10 weeks. Your local council will often provide pre-application guidance so that you can at least know what you are doing and what to expect along the way.

What is Permitted Development?

Permitted Development allows for the construction of garden rooms or “annexe’ buildings without planning permission. Considerations are taken as to the intended purpose of the garden room. In order for a garden room to be allowed under Permitted Development, there are some rules that have to be followed such as:

  • The garden room will not be used as accommodation.
  • The garden room cannot take up more than half of the area of land around your house.
  • The garden room cannot be erected at the front of the house or sticking out the side.
  • The garden room should have a maximum height of 2.5m.

Anything Else I Should Consider?

It’s important to consider how much actual space your new room will take up. You should try to have it be at least a metre away from your fences and boundaries. You should also consider surrounding trees and how much the roots of the tree will be damaged by your build. Foundations of garden rooms are generally fairly light and they can be put in using ground screw systems.

Of course, if you are considering selling your home in the future, a garden building can be an added perk and help you to get more money for your home; however, if the remaining garden space is unusable; this may be off-putting for a potential buyer.

Consider the roof; sloping or flat? The truth is they both have their benefits. With pitched roofs giving an illusion of internal space while flat roofs appear more contemporary and often blend into their surroundings more seamlessly.

If you are worried about overheating, as well as the importance of good insulation, consider an overhang to allow for shade, louvred screens to cast shade into the room, blinds and even air conditioning are some of the great options available to keep your room cool in those hotter months.


Can I Make an Eco-Friendly Garden Room?

Of course, most people will wish their room to have some type of power, possibly even water supply/drainage and perhaps heating as well. If you’d like to try and reduce or even eliminate the carbon footprint of your garden room, why not consider photovoltaic solar panels and a storage battery? These items coupled with professional airtight construction, MVHR (mechanical ventilation with heat recovery) with super insulation will not only lower those utility bills for the garden room but also allow for the space to be “off the grid”.
