A common question we get is can a garden room be attached to a house, and while the simple answer is yes, there are many considerations and oftentimes it is a difficult process. If you are considering your garden room options and have space outside your house, I give the low down below on what is possible, and the advantages and disadvantages of this process.

Types of Garden Rooms

First, let’s take a look at the different types of garden rooms so you can get an idea of the basic construction and style.

Standalone Garden Rooms

Standalone garden rooms are the most common option because they are flexible in terms of placement and allow you to utilise your garden space. These structures are usually placed on a concrete base or timber base, away from your property.

Lean-to or Attached Garden Rooms

Attached garden rooms are directly attached to your house – usually via one external wall. This involves either utilising an existing external door on your house or creating a new one that leads directly into your garden room.

Advantages of an Attached Garden Room

So, can garden rooms be attached to a house? Yes, and there are several advantages to this style of garden room, including:

Seamless Indoor-Outdoor Transition

The main benefit of having an attached garden room is the amazing indoor-outdoor transition it provides. It’s essentially like having a conservatory or building extension for much less cost. If you have a door fitted between your internal rooms and garden room, it makes it highly accessible and you are more likely to use it too.

Utilising Existing Infrastructure

Insulated garden room options that aren’t connected to your property don’t benefit from your existing infrastructure. This includes things like electricity, internet connectivity, and even plumbing or heating pipes. There is often more work and cost involved to hook these things up to a standalone garden office.

In contrast, it is far easier to utilize this infrastructure and extend cables and pipes to your attached garden office. The only barrier is the external wall and channels can be drilled into this where cables and pipes can be fed through.
Increased Accessibility and Convenience

Lastly, attached garden rooms are highly accessible and convenient to use all year round. You only have to walk from whatever room it is attached to, through an external door and you are in your garden room! Although the distance is small, it can be more effort to use your standalone garden room it it’s at the bottom of your garden, for example.

Disadvantages of a Garden Room Attached to Your House

While having an attached garden room can seem like a fantastic idea, there are some serious potential drawbacks to consider too:

Limited Flexibility in Placement

The placement and positioning of an attached garden room are incredibly limited. In most instances, you may have one or two external walls that you can attach to. Depending on the positioning of doors, and available wall space, it simply may not be possible to attach a garden room and have internal access.

Potential Disruption During Construction

A standalone garden room causes minimum disruption as all the work is done in your garden. In contrast, an attached garden room can cause disruption – especially if you need a new door created in one of your external walls. Some construction work may need to be done too in order to fix the structure to your house.

Impact on Natural Light and Views

You have to consider how the attached garden room affects the flow, views, and lighting of your property too. Will it reduce natural light entering your rooms or cause continual shadows? Maybe it will block views from particular rooms? You generally don’t get this problem with standalone garden rooms as they are further away from your house.

Planning and Building Regulations

Depending on the size and scope of the attached garden room and how it is attached to your house could also mean you need planning permission. This can increase the time, effort, and cost whereas generally, standalone garden rooms do not need planning permission providing they comply with building regulations.

Attached Garden Rooms are Possible but With Consideration

As you can see, it’s not a clear-cut choice and you must weigh up the pros and cons carefully before making a decision. Can a garden room be attached to the house?

Yes, but you may need planning permission, it can cause disruption, and oftentimes it can be more costly to get a bespoke attached garden office. In contrast, a standalone garden office is much easier to implement, doesn’t require planning permission, and causes no disruption to your home life.
